Insert CSS image sprites in place of icons

I want to replace icons with an image sprites, using the technique shown at [login to view URL] I think this job should take about an hour, if you already understand how to use portions of a image as background to a div in CSS. Therefore, please do not bid more than the maximum budget. The original page using icons can be seen at [login to view URL] The sprites are already composed into a single image: [login to view URL] The icon bitmaps are already correct positioned into tiles at 210px horizontally, and 168px tall. (However, you must add a responsive single scaling factor to display all the icons the correct size. Just use an arbitrary em value for the moment and I will fix it.) A start at revising the HTML and adding the needed CSS is available to you at [login to view URL] For each of the 7 icon classes used in the new HTML (e.g. phoneicon), just modify or add the needed CSS at the bottom of the file, in order to display the correct portion of the sprite image. Don't forget the hover state, which was set by #contactdocs li a:hover i {color: #aff;} for the icon, but now will use the part of the sprite image 168 px lower, on the second row. (Ignore the black hourglass on the right, which will be used on another page.) So that I know you have read this job description, you must make specific reference to it to have your bid considered. Thank you.
