My doubts

[mburt]

A simple clock script would be

Simple? Ouch, I can't even understand how that works. Well, I do, but it just seems really complex. I would prefer to write out the variables for time...

var date = new Date()
var hours = date.getHours()
var minutes = date.getMinutes()

And then display them simply by assigning innerHTML, or innerText (doesn't work in Firefox) a value.
Just my opinion though

Oh, and btw, what does "!==" mean?

There's no point creating variables if you're only going to use them once

innerHTML is non-standard and ugly. innerText is IE-only.

Oh, and btw, what does "!==" mean?

Opposite of ===: non-type-casting comparison. It's slightly more efficient than its more lax companion ==, so should be used where possible.

Thanks for your answer.
Anyway, the time display works! Thanks a lot.

What I mean by "best" is that,
which Internet browser that supports most of the codes, or is it all the same?

oh ya.. erm. JavaScripts.. they seems more complicating than CSS to beginners like me.

that's the application of "DHTML" that i'm refering to
