For example, I'd like to have links in body text be bold and blue, but I'd like the titles of blog posts (which are links) not to be blue.

I've been syling links through ATO > Body, Text, & Links > Link Default Color and Link Hover Cover, but this affects all links everywhere.

You will need to add some CSS in the ato->add HTML/CSS Insert->CSS Inserts option to style one of the two areas differently. You could try something like

#header a {color: red;

Thank you! I tried that exact code and it works for the site/blog title (and presumably everything else that's a link in the #header). I tried

h2 a {
color: red;
}

but that didn't work (it had no effect). Any suggestions?

there are many places in the theme options you can style links, the footer, the sidebars the links in posts. You need to go thru the various options to see what is avaiable.

However if you want all the header links one color and the rest another you could try adding this to the 'CSS Inserts' option

a {color: green !important;}
#header a {color: red !important;}

Thanks, this helped: Adding

!important;

did the trick, clearly overriding something else (I don't understand what was overridden, but it worked).

What I wanted to do was slightly different, though: I wanted to make all the h2 links a certain color. Meaning when the entire h2 is linked (as opposed to individual words), as on the blog main page, when blog post titles (h2s in my setup) are linked.

Here's the code that does that, for those who need it:

h2 a {color: black !important;}
