I'm a copywriter and I have to create a demo for an online magazine. I got as far as I could with my theme's standard features. Now I've bought Custom Design and want to tweak the site in CSS. I think what I need is to access (create?) the standard CSS file for my site, so as to be able to update it. Does that make sense? How should I go about it? Thanks for any help you can offer.
The blog I need help with is alegriaonline.net.
