I think the simplest way would be to add something like the following action method to a controller:
public class CssController : Controller {
public ActionResult GetCss() {
StringBuilder sb = new StringBuilder();
Dictionary<string, string> cssValues = new Dictionary<string, string>();
// populate dictionary with values from your database
sb.AppendLine(".myDivClass {");
foreach (var entry in cssValues) {
sb.AppendLine(entry.Key + ": " + entry.Value);
}
sb.AppendLine("}");
return Content(sb.ToString(), "text/css");
}
}
Now in your page you can reference it like so:
<link href="<%: Url.RouteUrl(new { controller= "CssController", action = "GetCss" }) %>" rel="stylesheet" type="text/css" />
OP EDIT: I made some small changes to the method, but the general premise remains. This is the version I used:
public class CssController : Controller
{
public ContentResult GetTheme()
{
var builder = new StringBuilder();
IDictionary<string, IDictionary<string, string>> css = new Dictionary<string, IDictionary<string, string>>();
/* Populate css object from the database */
foreach (var selector in css)
{
builder.Append(selector.Key);
builder.Append(" { ");
foreach (var entry in selector.Value)
{
builder.Append(string.Format("{0}: {1}; ", entry.Key, entry.Value));
}
builder.AppendLine("}");
}
return Content(builder.ToString(), "text/css");
}
}
