div with width:100% are different

[DickZN99]

I have some divs all set to width:100% on my website:\[code\]<div id="participate" class="test"> participate</div><div id="description" class="test"> <div id="brief" style="display:table-cell">&nbsp; </div> <div id="price" style="display:table-cell">&nbsp; </div></div><div id="bottom" class="test"> <div id="partners" class="test">&nbsp; </div> <div id="content" class="test">&nbsp; </div></div>\[/code\]Only #bottom has set display:table. When I set border I see #border is smaller excatly 2px than others div.When I set #border width:100.3% it is ok however this solution seems retarted to me. The problem is present in chromium and absent in firefox.Why is that and how can I get rid of it?Any hint'll be appreciated.
