InlineStyles

Squish a CSS stylesheet into any semantic html

HTML-formatted emails don't render uniformly unless the css is attached to the 'style' attribute of every element. Unless you want to maintain your templates with explicit inline styles you'll need to apply them automatically.

class Mailer < ActionMailer::Base
  def message(email)
    recipients email
    subject "Looks nice, eh?"
    html = render(:file   => "message.html",
                  :layout => "email_layout.html")
    body InlineStyles::Page.new.with_html(html).with_css(stylesheet_content).apply
  end

  protected

    def stylesheet_content
      File.read("#{Rails.root}/public/stylesheets/messages.css")
    end
end

InlineStyles uses the css_parser and Hpricot gems
