Possible Duplicate: Are new HTML5 elements like <section> and <article> pointless? I have decided to, finally, make the move to designing websites in HTML5. I have one question about the new tags. There are new tags such as; header, footer, navbar, etc.. Why are these tags preferred over the older method of using DIV ID's (eg. <div id="header"> ). I can see why this would make things simpler but wouldn't it be more confusing to have some tags that use HTML5 and some tags that use the older method? I, personally, find it more logical to use all or none, rather than a mixture. If I'm missing the

According to http://www.w3.org/TR/html401/interact/forms.html#h-17.4 , an input element should end with a single > and not a /> . Though that most browsers can handle an input element that ends with /> , is such an input element valid according to HTML syntax rules? In other words are elements like <input ... /> and <br /> valid in HTML 4? (This question is about HTML and not XHTML!!!) The syntax is valid in some places but doesn't mean the same as in XHTML, so don't use them. In HTML 4 <foo /> (where foo is the name of an element defined as EMPTY ) means the same as <foo>> which means the

What are the valid html elements, if any, that can be contained within a <a> tag? meder omuraliev Inline elements ( a, span, strong, em among others ) can contain other inline elements and text nodes. An anchor can contain a span, which can contain a text node. Generally, block-level elements may contain inline elements and other block-level elements. Generally, inline elements may contain only data and other inline elements. Inherent in this structural distinction is the idea that block elements create "larger" structures than inline elements.

问题 What are the key differences between HTML4 and HTML5 draft? Please keep the answers related to changed syntax and added/removed html elements. 回答1: HTML5 has several goals which differentiate it from HTML4. Consistency in Handling Malformed Documents The primary one is consistent, defined error handling . As you know, HTML purposely supports 'tag soup', or the ability to write malformed code and have it corrected into a valid document. The problem is that the rules for doing this aren't
