I think the point here is that the class attribute need not only exist for CSS/display purposes, it can also (and implicitly [I]does[/I]) denote semantic meaning. For instance, I can use DOM functions to identify all span tags that include class "LLLL" (or just all tags of any type with class "LLLL"), and do something non-display-oriented with the contents/attributes of those elements.@NogDogNov 04.2014 — #Well, that's just an example of what you can do with semantic mark-up, the point being that the mark-up can have meaning, and is not just an identifier for controlling how the data is displayed, though admittedly that's what 99%* of web developers probably use it for. E.g., search engines may give different weight to text within h1 tags -- as long as there is only one (or a very small relative number of them) in a page. The class attribute can be used to add additional meaning to its tag -- what you choose to [I][B]do[/B][/I] with that meaning is up to you. ?

Are additional and non-standard tags inappropriate for optimization?
Hello
Are additional and non-standard tags inappropriate for optimization?(for search engine)
for example:
[CODE]
<html>
<head>
<style>
#A{
color:red;
}
</style>
</head>
<body>
<LLLL id=”A”> www.webdeveloper.com </LLLL>
</body>
</html>
thank you.

I do not understand what you are seeking to achieve by using an undefined class???[/QUOTE]
