I think you might have to hack core for that – you’d probably have to set a custom class….
I was looking around for the class that contains wp_get_archives but I couldn’t find it. Does anyone know where it’s at?
I don’t think there is one. That’s why you’d have to hack core code. Which you can find on or about line 279 of /wp-includes/template-functions-general.php.
Keep in mind that you’ll have to rehack the file every time you upgrade wordpress.
Hey, y’know, here’s a thought: maybe widgetize your theme and hack the archives widget instead? Or set up your own in your theme’s functions.php?
Because you are using a theme which was properly constructed by the original authors 🙂 ; no core hack is necessary. The Archives have their own id. Hence the descendant selector and rule you need is #archives ul li {line-height: xxpx;}
