Composing with CSS.

[MicheleBS]

Dear Forum, is it possible to make use of CSS while composing new messages in HTML with Thunderbird?

I have already installed ThunderHTMLedit, with lots of satisfaction.
CSS would help me to customize the new messages further more.

Use inline styles. Don't link style sheets. Don't use a <style> tag.
