Here is where I put it:

#content {
	background: #003300; /*was #e3e3e3 */
	border-top: 21px solid #e3e3e3;
	padding-bottom: 20px;
}
#content-main {
	float: none;
	width: 100%;
}
<strong>.one-column .page, .one-column .post.author, .one-column .child-page, .post {
    width:750px;
}</strong>
.two-columns #content-main {
	float: left;
	width: 675px;
}
.three-columns #content-main {
	float: left;
	width: 460px;
}
.three-columns #content-main {
	float: left;
	width: 460px;
}
.three-col-right.three-columns #content-main {
	float: right;
}
.three-col-center.three-columns #content-main {
	width: 445px;
}

Still nothing happened. I also tried:

.two-columns #content-main {
	float: left;
	width: 675px;
}

Still nothing. Thanks again.

It worked. Thanks!!
