Change Theme / CSS based on user

Question

I am building a product that we are eventually going to white-label. Right now I am trying to figure out the best way to facilitate these requirements programmatically so th

Answer 1

I like the idea of using dynamic CSS using an ASP.Net Handler...

<link rel="stylesheet" href="style.ashx" />

style.ashx

<!--WebHandler Language="C#" Class="StyleSheetHandler"-->

StyleSheetHandler.cs

public class StyleSheetHandler : IHttpHandler {
        public void ProcessRequest (HttpContext context)
        {   
            context.Response.ContentType = "text/css";
            context.Response.ContentEncoding = System.Text.Encoding.UTF8;

            string css = BuildCSSString(); //not showing this function

            context.Response.Cache.SetExpires(DateTime.Now.AddSeconds(600));
            context.Response.Cache.SetCacheability(HttpCacheability.Public);
            context.Response.Write( css );
        }

        public bool IsReusable
        {
            get { return true; }
        }

}

The BuildCSSString() Function will build the css based on the values stored in the database and return it to override the base style on the master page.

Answer 2

I would avoid using the !important clause and instead just ensure their values appear in a <style> tag following the import of the regular style sheets.

Otherwise, I would do it the same way.
