full Wide screen image

[xjwantz]

I'm trying to place this picture at the background of my page in a \[code\]div\[/code\]. I'm trying to make it full screen "in width". so the size of the picture is \[code\]980x420\[/code\], but it just simply doesn't work. I know I'm missing something but I can't find it anywhere.CSS\[code\].Sil{ max-width: 100%; height: 300px; background: url(../Images/TALENT.png) no-repeat;}\[/code\]HTML\[code\]<div class="Sil"></div>\[/code\]
