How to send web page in email body with css

Question

I am creating a report on an asp.net web page using an html table and asp.net lables. The finished report I have to send by email in the message body. I've done this with the following c# code:

public bool SendEMail(List<string> emailList, string strSubject, string strMessage, bool isHTML)
    {
            MailMessage msg = new MailMessage();
            msg.From = new MailAddress(strFrom);
            //emailList is a list of email addresses to be sent to
            if (emailList != null && emailList.Count > 0)
                foreach (string em in emailList)
                {
                    msg.To.Add(em);
                }
            else
                return false;
            msg.Subject = strSubject;
            msg.Body = strMessage;
            msg.IsBodyHtml = isHTML;
            SmtpClient smtp = new SmtpClient(mailServer);
            smtp.Credentials = new System.Net.NetworkCredential(userName, usePass);
            smtp.Send(msg);
            msg.Dispose();
            return true;
        }

This works well but it only gets styles set within the form itself on each control individually. How can I incorperate css set in the html head or in a style sheet? Also is it possible to include skins?

Answer 1

Take a look to this chart :

I would recommend you to use inline styles instead of adding an external css sheet

Answer 2

styling html emails is a pain in the ass, with each client (gmail/hotmail/outlook/yahoo) applying their own styles to certain high level elements.

a good rule of thumb is to apply inline styles for example:

<span style="display:block; background:red;">blah</span>

have a look at campaign monitor to see which css rules work and litmus if you wish to take the pain out of the testing
