Help! – Lost all of left margin on posts

Hi!

In an effort to try to increase the padding/gap between my blog posts and my ride sidebar, I inadvertently did something that moved my posts all the way to the far left, with no margin at all now. If you visit the blog, you can see that it should be lined up in the center, with the left side of the post falling underneath “About”.

Any help will be greatly appreciated. I’m at a complete loss.

I believe that the problem could be in this part of the code:

#content {
margin-top:10px;
}
.post, .search .page{
text-align: justify;
overflow:hidden;
margin: 0 13px 0 0;
padding:12px 7px 12px 7px;
}

I was doing a little trial and error testing, however despite putting everything back how it originally was, the posts still remained all the way to the left.

Thank you in advance!!!
