AP div not positioning as expected!

Question

Actually, it's not taking on any positioning that I am trying to applt to it.
I have a circular logo that refers to 75 foot, and I am using a background image to help me position my content as needed, but the 75 foot logo div that I have positioned is falling behind the timer. Infact, the logo should appear infront of it because it has a higher z-index... another confusion for me then!
Have a look at http://www.fortnerf.co.uk and let me know why it doesn't want to work.
The AP div in question is called '75home', and I have placed it everywhere I can think of placing it on the page. It's just a simple div with a logo in it. It positions correctly in DW, but as soon as I test it with live veiw or in a browser, it moves!
The CSS for it and other AP divs is as follows:
#timer {
          position:absolute;
          width:390px;
          height:243px;
          z-index:1;
          left: 710px;
          top: 50px;
#win {
          position:absolute;
          /*width:460px;
          height:365px;*/
          z-index:2;
          left: -40px;
          top: 333px;
#homebuttons {
          position:absolute;
          width:465px;
          height:232px;
          z-index:3;
          left: 561px;
          top: 445px;
#75home {
          position:absolute;
          width:222px;
          height:222px;
          z-index:4;
          top: 261px;
          left: 572px;
I've also tried the following:
#75home {
          position:relative;
          width:222px;
          height:222px;
          z-index:4;
          margin-top: 261px;
          margin-left: -104px;
Thanks.

Pfft! I didn't know that!!
All these years I have been doing this and I have never known that. I guess it's been pure luck that I have never tried to use a selector that begins with a number before!
Thanks.
