Is the HTML TAG needed or is it optional?
In HTML5, according to the W3C, the HTML tag is optional. (Both the opening and closing tag.) As a matter of fact, and as part of a carry-over from HTML 4.01, the HEAD and BODY elements are also optional. That said, Internet Explorer has been known to fail to render HTML5 elements that are not inside a BODY element. And, while you can work without these tags, it will make understanding and maintaining the elements more difficult. In XHTML, none of these elements are optional. Neither the opening, nor the closing tags.
How are HTML and XHTML similar and different?
HTML and XHTML use a similar language syntax; tags, elements and everything. If you know HTML, you know messy XHTML: XHTML is a "clean" HTML. * Tags can be written in any case (uppercase or lowercase). * Some tags do not need to be closed. * HTML is parsed by systems based off of the Standard Generalized Markup Language (SGML). * HTML provides less accurate reading, and needs more time to read and manipulate data. * Some parsers cannot even manipulate HTML data, which is a big problem with more finicky devices (like mobile devices). * Tags must be written in lowercase. * All tags must be closed. * Tags must be properly nested -- no overlapping elements. * XHTML is parsed by XML parsers. * XHTML provides more accurate reading, and requires less time to read and manipuate data. * If a device can parse XML (which many modern devices can), the device can manipulate XHTML data to their needs (for example, to fit a website into the screen of a mobile phone).
