Please Help! Project Due! I Dont Know How To Do This Css Part! Help! Inline!

Hey guys, I missed a day of my XHTML class in college and he went over most of the CSS that day, I was sick with the flu and he said that day was the most important, so I'm lost, I need to "Remove any <b>, <i>, <u> and <font> tags and replace them with inline CSS code."

So i come up with something like this

<Style Type="css/text">
<B style="color:blue> This is my display text </b>
</style>

PLEASE HELP ME WITH THIS INLINE CSS! HELP! I'M LOSTTTT!

underline:
<div style="text-decoration:underline">Underlined text</div>

italic:
<div style="font-style:italic">Italicized text</div>

bold:
<div style="font-weight:bold">Bolded text</div>

THANK YOU SO MUCH! you helped out so much. I see now, i remember most of this stuff.
