Responsive / Relative Positioning Background Image - css

Question

Issue I'm having is the background image on the anchor as a before element needs to move with the text as you resize your screen.
I need the background image to maintain it's position ( e.g left: 20px;) with the text as you resize your screen.
Here is my CSS:
ul {
margin: 0;
padding: 0;
list-style-type: none;
}
ul li {
float: left;
width: 50%;
}
ul li a {
display: block;
padding: 15px 20px;
text-align: center;
text-decoration: none;
font-weight: bold;
position: relative;
color: #717171;
}
ul li a:before {
background: url(http://graphicclouds.com/wp-content/uploads/img/73-google-style-icons-thumb.jpg) no-repeat -11px -26px;
content: '';
display: block;
width: 34px;
height: 33px;
position: absolute;
top: 10px;
}
.link-1:before {
left: 20px;
}
.link-2:before {
left: 0px;
}
Here is a working example: http://jsfiddle.net/2KHS6/

Hope it fills your needs. You might want to set a min-width to avoid problems with small screens though. I did this basically:
ul {
margin: 0;
padding: 0;
list-style-type: none;
}
ul li {
display: inline-block;
width: 50%;
margin: 10px 0;
/* So things don't get crazy */
min-width: 160px;
/* center the child, the <a> */
text-align: center;
}
ul li a {
display: inline-block;
text-decoration: none;
font-weight: bold;
color: #717171;
/* Should be the same height as the img so it stays centered */
line-height: 33px;
}
ul li a:before {
background: url(http://graphicclouds.com/wp-content/uploads/img/73-google-style-icons-thumb.jpg) no-repeat -11px -26px;
content: '';
display: block;
width: 34px;
height: 33px;
position: absolute;
/* position the image at the left of the a. There are many methods to do this actually */
margin: 0 0 0 -50px;
}
