Logo disappeared after i added custom css,pls help

Hi
I am not a wp expert hence the problem:)
site is auromarealty.com
I was adjusting the position of logo and added custom css then I saved it and my logo disappeared. my original css for the header logo was;
/* GLOBAL */

#header{max-width:920px;margin:20px auto;clear:both;display:block;vertical-align: top; position:relative; height:75px;}
#header_logo{background:url(images/header_logo.png) no-repeat 0px 0px;display:block;float:left;text-indent:-3000px; width:100%; height:75px; position:absolute;}

In custom css, i added something what I found researching internet to push my logo further left. Now I can not remember the code or see it on css.

Then my Logo vanished.
I installed Firebug and when i inspect the header logo part, i see the code:
#header_logo {
background: url(“images/header_logo.png”) no-repeat scroll 0 0 transparent;
display: block;
float: left;
height: 75px;
position: absolute;
text-indent: -3000px;
width: 100%;

When I disable background part, I can see the logo
background: url(“images/header_logo.png”) no-repeat scroll 0 0 transparent;

When I disable background and height, i see tha logo and Tagline.
background: url(“images/header_logo.png”) no-repeat scroll 0 0 transparent;
height: 75px;

How can I get these back permanently to my site? I don’t know what to do from here to make this logo and tagline reappear.
Anybody pls help. I wanted to attach the firebug result but think can’t attach here. I think that part is overwritten but i can’t find how to fix. I installed the theme again but same problem
