I have this regular black text and I want to make it bold...but I have to do it within a style sheet..so how would I make that happen?

Try this in your stylesheet:

body {
font-weight:bold;
}

God bless!

If you don't want your entire page bold (as singingshanti's example makes it), you should enclose the text within <span> tags with class="bold" or something like that. Then, in your stylesheet:

.bold { font-weight: bold; }

:)
