Since you found out the id change is what caused the problem, the only solution is to use classes to style your html markups:

html

//some people don't know this but you can also put the style directly
into the asp.net control event if
visual studio doesn't support it in
the intellisense
<asp:Label id="label1" CssClass="test" style="color:blue;"
runat="server" />

css

.test { color:red; }

If you still want to use the id to style your code, then you can either put the long generated id into your css code or upgrade to asp.net 4 which gives control over your asp.net ids, for example:

<asp:Label id="label1" ClientIDMode="Static" runat="server"

/>

There are 3rd party solutions to give your control over the ids for asp.net 3.5 and below but they are not out of the box and needs some fiddling.
