make “continue reading >>” bold

Add

font-weight: bold;

under the appropriate CSS element. Or, if you’re adding the link manually in the post, e.g. Continue Reading >>, insert the code around the words you want bold. hard to tell without more info.

woops,

I meant, if you’re adding the link manually in the post, e.g.
<a href="">Continue Reading >></a>

insert the

<strong></strong>
code around the text you need bold.

forget about the code stuff. my bad.

I want it to happen automatically.

Here’s the code from single.php

<?php the_content('Continue Reading &raquo;' ); ?>

Is this what I edit? And, how would I do that?
