July 8, at 3: Participating in the mailing lists is fortunately not necessary.
I don't want to see extra space in my output. Isn't HTML good enough? HTML is probably the most successful document markup language in the world. The opinion at the workshop was a clear 'Yes': We could also take advantage of the redesign to clean up some of the more untidy parts of HTML, and add some new needed functionality, like better forms.
Why are browsers so fussy about XML? They were more accepting with HTML. HTML browsers accept any input, correct or incorrect, and try to make something sensible of it. This error-correction makes browsers very hard to write, especially if all browsers are expected to do the same thing.
It has also meant that huge numbers of HTML documents are incorrect, because since they display OK in the browser, the author isn't aware of the errors. This makes it incredibly difficult to write new web user agents since documents claiming to be HTML are often so poor.
It displays all right on my browser. All browsers know how to deal with correct Document.write alternative xhtml vs html5.
However, if it is incorrect, the browser has to repair the document, and since not all browsers repair documents in the same way, this introduces differences, so that your document may look and work differently on different browsers.
Since there are hundreds of different browsers, and more coming all the time not only on PCs, but also on PDAs, mobile phones, televisions, printers, even refrigeratorsit is impossible to test your document on every browser.
If you use incorrect HTML and your document doesn't work on a particular browser, it is your fault; if you use correct HTML and it doesn't work, it is a bug in the browser.
Where can I go to verify my document uses correct markup? W3C offers a service at http: Why do you say "user agent" everywhere, instead of "browser"? Search engines for instance read documents, but are not browsers. By using the term "user agent" we are trying to remind people of the difference.
For example, when you do a Google search often you will see under some of the search results something like "This web page uses frames, but your browser doesn't support them.
This threatened to cause a chaos of different non-interoperable versions of HTML. XML the X stands for Extensible allows anyone to use elements and elements from different languages, but for a browser or other user agent to know which element belongs to which language, you have to tell it.
The namespace declarations do just that. In fact, any modern browser. Include at the top of your document the line in bold here: Because of the way XML is defined, it is not possible to do tricks like this, where markup is generated by scripting while the parser is still parsing the markup.
You can still achieve the same effects, but you have to do it by using the DOM to add and delete elements. It cannot reliably be sent to legacy browsers. All three of these were deliberately kept as close as possible to HTML 4. The other two versions, transitional and frameset, were not updated, because there was nothing to update.
Modularization also makes it clear where it is OK to add new elements, and where it is not.
Areas that have received particular attention include better structuring possibilities, removing features that are duplicated in XML, usability, accessibility, internationalization, device independence, better forms, and reducing the need for scripting.
It has no fallback possibilities, so that if you use an image of type PNG for instance, and the browser can't handle that type, the only alternative is to use the alt text.An alternative is to use external script and style documents.
The Elements with id and name Attributes XHTML recommends the replacement of name attribute with id attribute. XHTML is an updated version of XHTML strict, and no version of HTML strict has ever included the target attribute.
|HTML Semantics, structure, and APIs of HTML documents||By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward and future compatibility. First off, one source of differences is immediate:|
|A vocabulary and associated APIs for HTML and XHTML||Also, note that the about: However, due to legacy constraints, it has gained another very important purpose:|
|Document Object Properties and Methods||Syntactically, the polyglot subset is found by either limiting the content to safe text contentthat is, text that gets interpreted the same way in HTML and in XML.|

The other two versions, transitional and frameset, were not updated, because there was nothing to update. XHTML stands for eXtensible Hypertext Markup Language. It’s actually a specific dialect of XML which is a generalised markup language. The main difference between XHTML and HTML4 is that all tags, once opened, must be closed.
"Differences from HTML4" describes the differences of the HTML specification from those of HTML4. attributes are allowed but Web developers are discouraged from using them and instead strongly encouraged to use an alternative solution: The border attribute on img.
lausannecongress2018.com(). @Sam: Thanks for your comments. I didn’t include IE in this lausannecongress2018.com() implementation simply because some form of browser sniffing is going to occur in order to serve the page properly to IE anyway.
Do you mean an alternative for XHTML? lausannecongress2018.com does work in normal HTML in probably all browsers.
