Be able to display a colored, bold, italic or underlined text into the Rich Text field. Use HTML tags in the Rich Text field.
Your text in the Rich Text field should looks like that:
[<HTML> ... your text is here ... </HTML>]
To make a text appeared please surround a desirable text by following HTML tags:
<B> ... </B> -> bold <U> ... </U> -> underlined <I> ...</I> -> italic <FONT color="#000080">...</FONT> -> colored
note: value for color is hexadecimal number or simple color name.
example: [<HTML><FONT color="red"><U><I>Microsoft</I> Internet Explorer</U> <B>5.0.</B></FONTt></HTML>]
P.S. Technically, you can use any HTML tag you want to present text, or even whole HTML page in the Rich Text field on the Web.
