Sidebar is Sticking Out

[starmometer]

Hi! I'm dumb when it comes to CSS and i can't find what to fix on my sidebar which is sticking out to the right side. On the homepage, the sidebar is ok but when you enter the single post (index.php), the sidebar goes outside the alignment. This problem is evident in Google Chrome and Firefox but not in Internet Explorer.

I tried to remove the margin from the code below but nothing happened:

#sidebar {
background: #D7D7D2;
float: right;
width: 300px;
padding: 10px 0px 10px 0px;
line-height: 18px;
display: inline;
}

The comments section also went out of alignment since i upgraded to Wordpress 3. Does it have something to do with the upgrade or just plain CSS?


Heres the snapshot of my sidebar:
