I am defining variable css files in head section on my pages (different skins) but can't define them when head has runat="server" (that is there by default) as <%%>
is not allowed in runat="server" sections removing runat="server" solves the problem but what is the differece (effect) of having this attribute or not in the head section:
<head>
<title> some title </title>
<link href="<%=skin_common%>.css" rel="stylesheet" />
<link href="<%=skin_color%>.css" rel="stylesheet" />
</head>
