Youve disguised something subjective with a veneer of objectivity. If it encounters an entity reference (other than one of the entities defined in this recommendation or in the XML recommendation) for which the user agent has processed no declaration (which Webwhere LO=LinearOperator, sp=Sparse matrix, HUS=HessianUpdateStrategy. With the exception of marking CDATA content, as well as dealing with SGML exclusions, you probably follow all of these rules. W3C. This applies to HTML as well als CSS and JS. But thats different from persuading the working developer to care. HTML Attributes - W3School This value must be less than or equal to the value of the max attribute. Although overlapping is illegal in SGML, it is widely tolerated in existing browsers. scripts and applets) that rely upon either the HTML Document Object Model or the XML Document Object Model [. a change. Under HTML 4, the interpretation of these values was case-insensitive, so a value of TEXT was equivalent to a value of text. However, the HTML validator at But when you write an XHTML document, you need to pay a bit extra attention to make your HTML document compliant to XHTML. I hadnt really given this much thought.

Ciao bella!
. SGML and XML both permit references to characters by using hexadecimal values. This means the author has used content of the script or style element within a CDATA marked section avoids the expansion of these entities. definition of each attribute in the reference manual indicates whether its value is case-insensitive. referred to in a CSS selector. Women are some of the strongest warriors the world has ever known, but they can be delicate and strong simultaneously. That's why the correct answer of this question is option D. The value of min and step define what are valid values, even if the step attribute is not included, as step defaults to 0. You can simply pass a callable as the method parameter.. playoffs. There are no substantive changes in this document - only the integration of various errata. prohibitions in XML. The system identifier may be changed to reflect local system conventions. Differences Between HTML and XHTML This is an XHTML document with a minimum of required tags: Note: The DOCTYPE declaration is not a part of the XHTML document itself. Back in the day all-caps HTML seemed to be the standard and as I recall the argument was that it was more readable / easier to distinguish between HTML and Content. File size isnt reduced by any meaningful amount. XHTML: In XHTML, names are case sensitive and it doesnt allow attribute minimization. documents. Use external scripts if your script uses < or Didnt know about the quotes, will remove them too. If some bot breaks because of that, then this bot is a badly implemented and soon its developer will notice that when it finds a website using a HTML minifier (the one cited in the post have 3.9 million downloads per week). Minifying HTML is so far down on the list of performance optimisations that it might as well not exist, outside of ultra-hyper-optimised stuff like the Google search page. See HTML Compatibility Guidelines for information on ways to ensure this is backward compatible with HTML 4 user agents. XHTML documents can be written to operate as well or better than they did before in existing HTML4-conforming user agents as well as in new, XHTML 1.0 conforming user agents. The file DTD/xhtml-symbol.ent is a normative part of this specification. Enable JavaScript to view data. The root element of the document must be html. Say what you will, I will always use self-closing tags for elements without a closing tag. A directory of Objective Type Questions covering all If the value of the element is GitHub The XHTML namespace may be used with other XML namespaces as per [XMLNS], although such documents are not strictly conforming XHTML 1.0 Replace the name attribute with the id attribute. HTML in XML while Id gladly use these features for minification actually writing code requires it to be readable and predictable so all you can skip X become even though syntax allows it you can not skip X, closing tokens and consistency of attributes makes things much easier to handle by a human being, even if machines dont care, being a bit verbose in source code makes your life in future much easier. 2.3.5 Attribute Minimization. I always validate my HTML, always. It is a reformulation of the three HTML4 document types as applications of XML 1.0 [XML]. Bing, for instance, expects optional head and body tags or it could fail to read some metadata. The following example shows the difference Some input types have a default minimum. these DTDs locally you should download one of the archives of this version. For non-empty elements, end tags are required. Your Questions Answered #4 | HTML5 Doctor However, In order to ensure that XHTML 1.0 documents are well-structured XML documents, XHTML 1.0 documents MUST use the id attribute when defining fragment Browsers are extremely tolerant but it doesnt mean we have to push these boundaries, they bring pretty much nothing except a lighter code (which is still important but considering you ship JS libraries beside). Here is a list of the minimized attributes in HTML and how they should be written in XHTML: The lang attribute applies to almost every XHTML element. It specifies the language of the content within an element. If you use the lang attribute in an element, you must also add the xml:lang attribute, like this: Alternate ways of accessing the Internet are constantly being introduced. In SGML these references could be made using either &#Xnn; or &#xnn;. Although a restricted form of SGML, XML nonetheless preserves most of SGML's power and The Document Object Model level 1 Recommendation [DOM] defines document object model interfaces for XML and HTML 4. Which of the following statement is true

and not

). I feel like minified attributes already became standard. XHTML documents as media type text/html. Browsers attempted to fix all the problems by guessing what the author meant, which wasnt always correct. HTML 4 and XHTML both have some attributes that have pre-defined and limited sets of values (e.g. documents as defined above. is not as clear as and as a developer you need to remember that you may not be the only person working on a project. About the only thing I miss from the HTML way is attribute minimalization. This includes XML whitespace handling, CDATA sections, doubling of name attribute values, the case of pre-defined value sets, and hexadecimal entity references: Peeling away from these rules, this looks a lot less like were working with XML, and more like working with HTML. Simplicity is rarely as simple as minimalists like to make it sound. ! "&"). The low attribute specifies the range where the gauge's value is considered to be a low value. See Section 6.2 of [HTML4] for more information. XML does not support attribute minimization. Such a document must meet all of the following criteria: It must conform to the constraints expressed in one of the three DTDs found in DTDs and in Appendix B. Simplify one dimension and you often complicate another; perfectionism tends to increase overall complexity. I would love to see the VS Code plugin that converts from XHTML way of writing to HTML of writing. These are personal syntax preferences presented as best practices, and that theme runs through the supporting articles. A newer Other values have been defined in other HTML5 Due to the fact that XHTML is an XML application, certain practices that were perfectly legal in SGML-based HTML4 [HTML4] must be Good article. What you refer as Linux is actually GNU + Linux etc etc. All the XHTML tags and attributes need to be written in lower case only. If you need to use For completeness, the normative versions of the DTDs are included here: The file DTD/xhtml1-strict.dtd is a normative part of this specification. The user agent must use the definition from CSS for processing whitespace characters [CSS2]. Just because you can, doesnt mean that you should. For me this sort of attribute declaration feels less readable probably because Im being asked to parse it as Disabled is Disabled which just makes my eye twitch. Some link previewers also fail. Remember that element and attribute names may be lowercase or uppercase. So XHTML comes with a much stricter error handling. For example, the HTML 4 Strict DTD forbids the nesting of an 'a' element within another 'a' element to any descendant depth. With build chains and HTML optimizers this is not necessary and just trains new web devs to not care and write code as if its 1990 again. Rephrasing and reordering, this is the essence: How does this look like in practice? The autocomplete attribute has two possible values, on and off (case-insensitively), according to HTML5 LC. The Cascading Style Sheets level 2 Recommendation [CSS2] defines style properties which are applied to the parse tree of the HTML or XML The isindex element is deprecated in favor of the input element. Guidelines for creating compatible documents can be All elements other than those Additionally, an attribute value may or may not be required as dictated by other configuration such as the. if(condition){ Failing to use end tags (or void elements) properly can result in errors unless youve purposefully told your linter to ignore them. corresponding items attribute requirements or the location allowing mixing of attributes. These DTDs approximate the HTML 4 DTDs. the semi-colon) that make up the entity reference. Otherwise, were left with the mess from back in the day when most browsers had to be very forgiving of the horribly broken HTML which was rampant at the time. WebHTML with Attribute Minimization: However, if you are using purely HTML you must use the selected attribute in your tag as follows: HTML with Full Attribute Specification: Data masking is an inborn defect of measures of disproportionality in adverse drug reactions signal detection. WebIn HTML, you can leave out the attribute value in such cases. HTML, as originally conceived, was to be a language for the exchange of scientific and other technical documents, suitable for use by non-document specialists. The changes in this document reflect corrections applied as a result of comments submitted by the The required attribute in HTML makes a field mandatory to be filled by the user. Required in HTML is a boolean attribute. We can just write the attribute required in the element without specifying its value as the HTML supports attribute minimization. By default, the required in HTML has a value of true. Ok, well the tag has got to terminate before it right? The complete set of DTD files together with an XML declaration and SGML Open Catalog is included in the zip file and the gzip'd tar file for this specification. HTML isnt XHTML. For example, dropping attribute quotes to save a few bytes will cause more issues than simply continuing to follow the XHTML spec, especially given attributes are often dynamically injected these days. (as a standard) and for adapting HTML to vertical, highly specialized, markets. This specification was written with the participation of the members of the W3C HTML Working Group. This process may change attributes at the level. HTML, back then, was loaded with

elements for layout, packed with presentational code, largely invalid (as its still today), with wildly varying user agent support. For an example, see [XHTML+MathML]. One thing influenced by XHTML that has never gone away and is so deeply, deeply entrenched in the web dev world is the typing of HTML element selectors in lowercase within the CSS. Both of these attributes are designed to be used as fragment identifiers. This plethora of new elements has led to interoperability problems for documents across different platforms. In XHTML-conforming user agents, the value of the encoding declaration of the XML declaration takes precedence.

here is an emphasized paragraph.

,

here is an emphasized paragraph.

. Within the XHTML namespace, user agents are expected to recognize the "class" attribute. Additionally, an attribute value may or may not be required as dictated by other configuration such as the. If a document is to be served as multiple media types, the HTTP server must be used to set the encoding of the document. How can you manipulate a minimized attribute value in profiling mechanism, servers, proxies, and user agents will be able to perform best effort content transformation. The following hints will reduce this effect for documents which are served without LOL. No one ever made a slow website into a fast one by leaving out closing tags. Similarly, dropping closing tags causes untold woes when the HTML is more than a few lines or worked on by a few developers, and youre not sure if its supposed to be nested or simply an error. Therefore, style sheets should be able to continue using the shorthand "#" As formally defined, HTML 4 does not allow attributes without a value. What is commonly regarded as attribute without value, as in Leaving out quotes for attributes, especially for URLs, is a horrible idea. XHTML was developed to make HTML more extensible and flexible to work with Note that in XHTML 1.0, the name attribute of these elements is formally deprecated, and will be removed in a subsequent version of XHTML. Minimization text A and text B could display bold in html but not in xhtml. These modules will permit the combination of existing and new feature sets when developing content and when designing new user agents. What are the benefits? Minifying HTML is so far down on the list of performance optimisations that it might as well not exist, outside of ultra-hyper-optimised stuff like the Google search page. Its totally valid to do these things for your enjoyment of minimalism or optimisation. Perhaps some of them make your code more readable too. It may be useful to pass a custom minimization method, for example when using a frontend to this method such as scipy.optimize.basinhopping or a different library. Therefore, in XHTML 1.0 the id attribute is [ because of rules I cant demonstrate crossing tags by html and by xhtml with the bold tag ]. WebAttributes should be quoted Tags should nest not tag Unused elements may be minimized Unknown attributes are ignored by the browser. Still, I wouldnt suggest adopting all of these suggestions. HTML attribute: min - HTML: HyperText Markup Language | MDN The min attribute defines the minimum value that is acceptable and valid for the input containing the attribute. If the value of the element is less than this, the element fails validation. This value must be less than or equal to the value of the max attribute. Some input types have a default minimum. compliant with HTML 4. All browser compatibility updates at a glance, Frequently asked questions about MDN Plus. In XML documents, you must use the Some of the benefits of migrating to XHTML in general are: The following terms are used in this specification. And I agree, XHTML was a bit of too much constraints but it did a lot of good to HTML according to me. A paragraph and a list, for example, are written like this in XHTML: In HTML, however, you can write them using only this code (which is valid): Developers also learned to write void elements, like so: This is something XHTML brought to HTML, but as the slash has no effect on void elements, you only need this: In HTML, you can also just write everything in all caps: It looks like youre yelling and you may not like it, but its okay to write it like this. changed to NMTOKEN. Indicate any required and optional input, data formats, and other relevant information. A lot of the XHTML points actually made sense. This flexibility, DigitalOcean provides cloud products for every stage of your journey. Consistency is a lot easier than special rules. HTML
,
(HTML is my main focus area, so Im augmenting this by links to some of my articles.). The html, head, title, and body elements must be present. characters, it is illegal. Note that in order to produce a Canonical XHTML document, the rules above must be applied and the rules in [XMLC14N] must also be applied to HTML contributes very little to overall page sizes and this modern way of writing makes pages harder to process. use Attribute Minimization Is Forbidden Wrong: < input type ="checkbox" name ="vehicle" value ="bus" What is A Callback Attribute minimization Work by W3C is addressing ways to specify conformance for documents involving multiple namespaces. Sorry, I cannot agree to most of this. You dont HAVE TO close an element in HTML but it helps to know where it ends (but people dont really understand the concept of elements in HTML). hypertext. HTML low Attribute - W3School img, and map elements, and it will be removed from XHTML in subsequent versions. In both cases, if omitted, the value defaults to 1. Attribute values are generally case-insensitive. We can just write the attribute required in the element without specifying its value as the HTML supports attribute minimization. I will stick to the XHTML way, thank you. It means you need to explicitly state the attribute and its value. You can tell by the rough dates of the specifications, too: HTML 1 1992, HTML 2.0 1995, HTML 3.2 1997, HTML 4.01 1999; XHTML 1.0 2000, XHTML 1.1 2001; HTML5 2007. But were not done yet. The attribute minimization is described as an in the way of checked. Youve learned HTML the XHTML way. That is the XHTML way of writing HTML, and its lasting impact on the field. Note that this recommendation does not define how HTML conforming Attribute-value pairs must be written in full. How to attribute Minimization ? Because of that EVERYONE in the web dev world began putting references to HTML elements in lowercase in their CSS when its not needed, when it makes stylesheets less readable, when hardly anybody knows why they do it, and nobody wants to budge from it. When defining fragment identifiers to be backward-compatible, only strings matching the pattern [A-Za-z][A-Za-z0-9:_.-]* should be used. I still use because the lang attribute. You will learn more about the XHTML document itself. WebAttribute Minimization XHTML does not allow attribute minimization. Element and attribute names may not be in lowercase. entities such as < and & will be recognized as entity references by the XML processor to < and & respectively. XHTML that when the XML declaration is not included in a document, the document can only use the default character encodings UTF-8 or UTF-16. declared in the DTD as EMPTY must have an end tag. Unfortunately, many non-browser parsers do expect optional and closing tags. If a user agent encounters an element it does not recognize, it must process the element's content. Same for semicolons, I prefer to always use them; consistency over maximal minimalism. By using this website, you agree with our Cookies Policy. However, CSS selectors and parts of the Javascript API use ID attributes, so that is likely why the name attribute feel out of favor, with the exception for forms. Youre bypassing a standard that can be used by editors / code processors to more easily distinguish between attribute / value, potentially creating issues with code scanning. To validate it properly requires having to know all possible elements and their optional rules, including browser specific extensions. richness, and yet still retains all of SGML's commonly used features. defined to be http://www.w3.org/1999/xhtml. Here is the example showing syntax , XHTML does not allow attribute minimization. Tooling is available, too: html-minifier is probably the most established and able to handle all HTML optimizations. The details of this family and its You are very likely writing HTML, the XHTML way. In addition to simplifying the document structure, HTML added support for Attribute Minimization. Some have lucky shoes. The following characters are defined in [XML] white space characters: The XML processor normalizes different systems' line end codes into one single LINE FEED character, that is passed up to the application. Required fields are marked *. XML all the things. For HTML, this had a profound effect: The effect that we learned to write it the XHTML way. ?> needless confusion and complexity rather than simple consistency. Unfortunately, this constraint cannot be expressed in the XHTML 1.0 DTDs. Note: When the data entered by the user doesn't adhere to the min value set, the value is considered invalid in constraint validation and will match the :invalid and :out-of-range pseudo-classes. What is required Attribute in HTML? - Scaler Topics Web. If the input has no default minimum and a value is specified for min that can't be converted to a valid number (or no minimum value is set), the input has no minimum value. The DOCTYPE HTML: In HTML, the DOCTYPE is mandatory even though it has no value. CSS defines different conformance rules for HTML and XML documents; be aware that the HTML rules apply to XHTML documents delivered as HTML and the XML rules apply to XHTML documents delivered as There were reasons everyone preferred XHTML back in the early 00s. It is intended to be used as a language for content that is both XML-conforming and, if some simple guidelines are Examples might be simplified to improve reading and learning. This document is also available in these non-normative formats: Multi-part XHTML file, PostScript version, PDF version, ZIP archive, and Gzip'd TAR archive. In order to be contains all the descendant elements. XML does not support attribute minimization. Such a declaration is required when Consider this case: Its not intuitive what the result should be. I may be old fashioned (I first learned HTML in the 90s and I made my first commission using it in the early 2000s) but I find that learning and respecting the XHTML mantra helps you be a better front end developer, because its less sloppy and more predictable. I dont think write HTML the HTML way makes it better in any way, on the other hand I really think it makes less safer. The HTML 4 document object const input = document.querySelector('input'); console.log(input.getAttribute('value')); // Hello console.log(input.value); // Hello The XHTML family is designed with general user agent interoperability in mind. The annotated contents of this file are available in this separate section for completeness. changed. Because step defaults to 1, valid values include 7.2, 8.2, 9.2, and so on. Both snippets are syntactically valid in html4 and html5. The first is not valid xhtml, because in xhtml an attribute value is required. On the ot Nor did I add the backslash for br or hr tags. Essentially this means that all elements must Differences in parsing will produce different visual or aural results, depending on the selectors used. It specifies the language of the content within an element. In an HTML video element, I want to use the minimized controls attribute:
