Customising the theme

Absolutely. Sounds like everything you need to do can be done by adjusting the css. It’s easiest to find the values you want to change using Firebug. Here is a tutorial, in case you haven’t used it before.

You should never edit the theme files directly, but you can try using a custom css plugin, or adding a child theme and only changing some css.

Thanks! ??

You’re welcome.
