Html template

[Tizianol8]

Is not possible to specify complex html in the template?
I can set simple html element with inline css styling (like html template example), but if i want specify the body background color? Or a global style properties for rendering pourpose like this: (??)

/* Client-specific Styles */

outlook a{padding:0;} /* Force Outlook to provide a "view in browser" button. */

body{width:100% !important;} .ReadMsgBody{width:100%;} .ExternalClass{width:100%;} /* Force Hotmail to display emails at full width /
body{-webkit-text-size-adjust:none;} / Prevent Webkit platforms from changing default text sizes. */

Thanks a lot for this usefull project!
