i want to know how to make just certain words or lines in my entries bold or italicized. i know on other sites you can use <i> or <b> and <marquee> but what about xanga?

For bold and italicized, those tags work.

<b>blahblah</b> makes things bold.
<strong>blahblah</strong> also makes things bold.
<i>blahblah</i> make things italicized.
<em>blahblah</em> makes things italicized.
<u>blahblah</u> makes things underlined.

You have to click the "Edit HTML" thing when you're typing your weblog entry..
If you don't want to switch, you can just type Ctrl+B/Ctrl+I/Ctrl+U before typing the word to make them Bold/Italisized/Underlined.
An even EASIER why to do it is to type out your entire blog entry FIRST, and then just click in between the letters in any word and click Ctrl+B/Ctrl+I/Ctrl+U.

oh neat! thanks eve! hmm i didnt know <em></em> was italic.. i thought you had to use <i></i> or can we also use that too? hm but thanks!

thanks. i got it now. :)

and what about changing the font size in an entry?

<font size=#>blahblah</font>

I think that works.. In the "Edit HTML" part.
