CSS issues

[hyphy]

hey,

I've been trying to make my layout work in IE for the past 3 days and haven't been able to find a solution.
Have a look at:

How can i make the catgegories box (#sidecontainer) stay in the same position that it is in when using Firefox in IE? And why does IE throw the footer out?!

I've tried using margin to fix stuff up for IE, but that has not fixed the footer problem. Can anyone help?

Everything i do just seems to break more stuff?!

Here are my containing div's:

.post /* class container inside main container for posts */
{
margin: 30px 330px 40px 25px;
/*border: 1px #cccccc solid;*/
}

#sidecontainer /* container beside post class */
{
margin: 0 25px 5px 0;
border: 1px #cccccc solid;
top: 30px;
right: 5px;
display: block;
width: 285px;
float: right; /* IE is just stupid */
}

* html #sidecontainer
{
margin: 30px 13px 0 0;
}

EDIT: kinda fixed it, but the footer still has issues.

thanks,

hyphy.
