That's the ticket. &nbsp;Inline CSS. Thanks!

<div class="content wysiwyg-content">
I have an app that send emails. &nbsp;The body of the email can be defined as HTML. &nbsp; I want to use the bgcolor attribute of &lt;body&gt; to set the background color of the email. &nbsp;Simple enough. &nbsp; <a href="http://www.w3schools.com/tags/att_body_bgcolor.asp" rel="ugc">http://www.w3schools.com/tags/att_body_bgcolor.asp</a><br />
<br />
However, &quot;The bgcolor attribute of &lt;body&gt; is deprecated in HTML 4.01.&quot; &nbsp;and &quot;The &lt;body&gt; bgcolor attribute is not supported in HTML5. Use CSS instead.&quot;<br />
<br />
So, I'm using Thunderbird as my email client, which is not a browser of course. &nbsp;If I use the bgcolor attribute, Thunderbird recognizes it and all is well. &nbsp;<br />
<br />
So, how do HTML / HTML5 / CSS and &nbsp;non-browser apps like Thunderbird work together / or not work together? &nbsp; If I use the bgcolor attribute to set the background color of the email, do I run the risk of it not working at some point in the future? &nbsp;If yes, would that imply that Thunderbird no longer supported HTML 4, but instead switched to HTML5? <br />
<br />
Thanks for any feedback.

HTML / HTML5 / CSS / Non-Browser apps like Thunderbird.

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.

HTML

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

Thunderbird is an email, newsgroup, news feed, and chat (XMPP, IRC, Twitter) client that supports POP and IMAP and LDAP address completion. The vanilla version is not a personal information manager, although the Mozilla Lightning extension adds PIM functionality. Thunderbird can manage multiple email, newsgroup, and news feed accounts and supports multiple identities within accounts. Features such as quick search, saved search folders, advanced message filtering, message grouping, and labels help manage and find messages. Thunderbird incorporates a Bayesian spam filter, a whitelist based on the included address book, and can also understand classifications by server-based filters such as SpamAssassin. Extensions allow the addition of features.
