XHTML documents as media type text/html. Some have even been elevated to best practices for HTML. The following example shows the way in which XHTML 1.0 could be used in conjunction with the MathML Recommendation: The following example shows the way in which XHTML 1.0 markup could be incorporated into another XML namespace: A conforming user agent must meet all of the following criteria: White space is handled according to the following rules. :-), One note of English syntax, Documents may not be well-formed, is an ambiguous construction. See HTML Compatibility Guidelines for information on ways to ensure this is backward compatible with HTML 4 user agents. HTML is an example of a language defined a change. HTML isnt XHTML. By using this website, you agree with our Cookies Policy. Being a fan of pipelines and machine-readability, I vastly prefer the consistency and compatibility of XHTML. XHTML is a stricter, more XML-based version of HTML. When using the min attribute, ensure this minimum requirement is understood by the user. The root element of the document must contain an xmlns declaration for the XHTML namespace [XMLNS]. XHTML is a family of current and future document types and modules that reproduce, subset, and extend HTML4 [HTML4]. The annotated contents of this file are available in this separate section for completeness. WebAttribute Minimization XHTML does not allow attribute minimization. small set of guidelines. This difference is necessary because XML is case-sensitive e.g. I would argue that articles such as this, while innocently describing the true specification for HTML5, is actually normalising bad practice. Ok, well the tag has got to terminate before it right? Affordable solution to train a team and make them project ready. 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.

It means you need to explicitly state the attribute and its value. the semi-colon) that make up the entity reference. Such a declaration is required when Under XML, the interpretation of these values is case-sensitive, and in XHTML 1 all of these values are defined in lower-case. WebAttribute Minimization XHTML does not allow attribute minimization. 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. The file DTD/xhtml-special.ent is a normative part of this specification. ISO/IEC 9945-1:1990 [POSIX.1]: This version of XHTML provides a definition of strictly conforming XHTML 1.0 documents, which are restricted to elements and attributes from the XML and XHTML 1.0 namespaces. If this is not possible, a document that The following example shows this difference , You must nest all the XHTML tags properly. SGML has been around since the middle 1980's and has remained quite stable. I hadnt really given this much thought. Problem: Highlight.js transforms minimized HTML5 attributes to non-minimized XHTML attributes. Use external scripts if your script uses < or XHTML documents can utilize applications (e.g. The original idea to allow sloppiness to be the language of the Web is not something I support.

Some have lucky shoes. It feels like there are two options on the table, write a more declarative and readable code that works or write a smaller and flexible code that (may) also works and I dont really see any gain in that. For these definitions, see [HTML4] and [RFC2854] respectively. Fewer mistakes. If not explicitly included, step defaults to 1 for number and range, and 1 unit type (second, week, month, day) for the date/time input types. what is attribute minimization in html. Such prohibitions (called "exclusions") are not possible in XML. XML does not support attribute minimization. XML is a markup language where all documents must be marked up correctly (be "well-formed"). For completeness, the normative versions of the DTDs are included here: The file DTD/xhtml1-strict.dtd is a normative part of this specification. Great read, but Id just give it to Pug to format everything for me. This document is the second edition of the XHTML 1.0 specification incorporating the errata changes as of 1 August 2002. compatible with this convention, style elements should have their fragment identifier set using the id attribute, and an XML stylesheet declaration should reference this entity reference (e.g. 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). For an example, see [XHTML+MathML]. Closing empty tags. The following syntax shows the correct way of writing above tags in XHTML. Rephrasing and reordering, this is the essence: How does this look like in practice? In XML, it is relatively easy to introduce new elements or additional I agree with some of your preferences, and its good to be reminded we have multiple valid options. agents have silently ignored incorrect usage of the ampersand character in HTML documents - treating ampersands that do not look like entity references as literal ampersands. document itself.

. I mean, you dont have to use line changes in JavaScript, but its horrible to read if you dont use any. Boolean Attributes, Yes they are completely valid. From W3C: (On SGML & HTML) Some attributes play the role of boolean variables (e.g., the selecte and style sheets within "comments" to make the documents backward compatible is likely to not work as expected in XML-based user agents. Entity references as hex values may not only be in lowercase. Work by W3C is addressing ways to specify conformance for documents involving multiple namespaces. And some things I do thats the XHTML way because it is easier, All hex entity references must be lowercase, be it color codes, or IDs it is much more manageable to keep it all lowercas. What is the XHTML way of writing HTML, and what is the HTML way of writing HTML? And both are valid with HTML5. 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. 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. Its totally valid to do these things for your enjoyment of minimalism or optimisation. The XML document object model specifies that element and attribute names are returned in the case they are specified. The following elements are not allowed to have any other element inside them. contains all the descendant elements. In XML, URI-references [RFC2396] that end with fragment identifiers of the form Due to the fact that XHTML is an XML application, certain practices that were perfectly legal in SGML-based HTML4 [HTML4] must be The following example shows the syntax . 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. Every single time.

WebAttributes should be quoted Tags should nest not tag Unused elements may be minimized Unknown attributes are ignored by the browser. This document has been produced as part of the W3C HTML Activity. ! My code still validated perfectly. If a user agent encounters an attribute value it does not recognize, it must use the default attribute value. declared in the DTD as EMPTY must have an end tag. 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. HTML contributes very little to overall page sizes and this modern way of writing makes pages harder to process. Therefore, in XHTML 1.0 the id attribute is The DTD subset must not be used to override any parameter entities in the DTD. In an XML document, the character encoding of the document is specified on the XML declaration (e.g., ). Everyone wants an edge during the N.B.A. 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. Minimizing code to the point that it is non-obvious what it does might shave off a few bits, but only at great cost to legibility. XML. And I vehemently disagree about omitting default values as this again created a maintainability issue (and perhaps edge-case issues in some browsers?). Nor did I add the backslash for br or hr tags. It might depend on how easy it is to add to your existing setup. In SGML and XML, these are Case-sensitive Treat attributes in case sensitive manner (useful for custom HTML tags) Collapse boolean attributes Omit attribute values from boolean Note: be aware that if a document must include the character encoding declaration in a meta http-equiv statement, that document may always be interpreted by HTTP servers and/or user agents as Sorry, but I strongly disagree with the point that end tags are not required. This specification defines the Second Edition of XHTML 1.0, a reformulation of HTML4 as an needless confusion and complexity rather than simple consistency. Required fields are marked *. So XHTML comes with a much stricter error handling. XHTML documents must use lower case for all HTML element and attribute names. Next within the remaining possibilities, collecting personal data should be minimized. Because of this change, care must be taken when converting existing HTML documents. They let us lean on other peoples expertise like yours! For compatibility with these types of legacy browsers, you may want to avoid using processing instructions and XML declarations. The XHTML entity sets are the same as for HTML 4, but have been modified to be valid XML 1.0 entity declarations. SGML gives the writer of a DTD the ability to exclude specific elements from being contained within an element. Attribute names must be in uppercase B. It also brings some sanity to those who come from backend languages or even Javascript, as the syntax in those languages require beginning and ending tokens. It is not possible to spell out such or --. 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: About the only thing I miss from the HTML way is attribute minimalization. The file DTD/xhtml1-frameset.dtd is a normative part of this specification. It specifies the language of the content within an element. echo ' disabled="disabled" '; User agents that access XHTML documents served as Internet media type, User agents that access XHTML documents served as Internet media types. HTML permits attribute minimization, where boolean attributes can have their value omitted entirely, e.g.,
