Widget issue

I tried to put social icons on top of my blog was not successful so I opted to put it in widget in side bar. I want it to float LEFT, I have left in the CSS and it’s still on the right. I inspect with firebug and it says it’s right. I even tried putting important and still a no go. What am I doing wrong?
(site is in maintenance mode so you can’t see it)

This is what I have in my CSS
#header_icons img {
float:left!important;
height:32px;
width:32px;
margin:0;
margin-right:10px;
}
#header_icons {
float:left!important;
padding-top:5px;
width:300px;
z-index:-9999;
padding-bottom:10px;
}
I think it has something to do with my permission because when I went to server via FTP changes weren’t there. This is very strange

It worked sfter I fixed it on server. Weird!
