Hello!
This is probably a very,very easy question for most of you, but I saw this tag somewhere, it was <em> I was just wondering what it did.
Thanx!

It's Emphasis and all it does is italisize the font. I checked on FrontPage.

Oh ok thanks!

it kinda makes the text look like italics.
<i> text here </i>

em = emphasis (important information).
