How would I name this HTML code so I could edit it with CSS? [closed]

Tags: html,css

Problem :

I have this ad code to put on my website, but I need to put it at the bottom of the page (and centered). At the moment I have this code:

<script type="text/javascript">
var var1 = "728";
var var2 = "90";
var var3 = "728x90";
var var4 = "21676";
var var5 = "d119a02021ce7f2804da25fd308f24b0";
</script><script type="text/javascript"src="//"></script>

How could I name the piece of code so I could edit it like

.nameofclass {
    position: absolute;
    left: 100px;
    top: 150px;

But the left and top of the position be the bottom middle.

So I pretty much need to know how to name it a class then in the CSS change it to the bottom middle position.

Solution :

You'll want something like:

<div class="nameofclass">Some contents</div>

Avoid the center tag; it's not supported. If you need the element to appear centered, do it in the CSS.

As already stated, it's considered polite to research your question before asking. This should be answered by any CSS tutorial.
