Problems with changing background color

I'm current designing humboldtcleaners.com on wordpress but I'm having trouble changing the background color.

I went to style.css sheet (from the wordpress editor) and changed the "background:#f3edd3" to "background:#94750c".

When I update the changes, the website background stays the same. Is there alternative way to change the background or I'm doing something wrong?



Code from style.css

/*------------------------------ PAGE ------------------------------*/
@import url(css/font.css);

html {
background:#f3edd3;
}
body {
color:#252525;
position:relative;
background:url(images/back-top.png) repeat-x ;
font-family:'pt_sansregular';
font-size:13px;
}
a {
color:#9e7353;
text-decoration:none;
}
a:hover {
text-decoration:underline;
}
a.post_ttl, .post-caption h1 {
color:#307b05;
font-family: 'pt_sansregular';
font-weight:bold;
font-size:24px;
}
h2 a.post_ttl:hover{
text-decoration:underline;
}
