HTML IF Statement

Question

I just wanna know how to do an if-statement in simple HTML. Like the [if IE6] thingy

I'd like to do something like this

[IF 5>6]

How's the syntax? I can't seem to find anything but [If!IE6] and things like that, is that even possible?

Thanks a lot

Edit: I want to compare just scalar numbers, cause I have a dynamically created HTML. For example [If 4 == 6]. I DON'T WANT TO CHECK IE VERSIONS.

Answer 1

If you want to check for browser versions:

<!--[if lt IE 7]>
    <!-- For LOWER than IE7 -->
<![endif]-->

<!--[if IE 6]>
    <!-- For JUST IE6 -->
<![endif]-->

<!--[if gt IE 7]>
    <!-- For HIGHER than IE7 -->
<![endif]-->

Other than that, you cannot use if statements in HTML, as it is a markup language and not a programming language. You need to do it either server side or with Javascript.
