(I don't know whether I've posted this question before. If I have, I offer my sincere apologies. I couldn't find it in a search!)
I'm paying for "Customized CSS" on my blog. I maintain the CSS in coordination with my private website. The website and the blog link to each other, and I try to keep them looking the same! Thus, they share *much* CSS, and anytime I change the CSS on my website, I must return to the WordPress blog and apply the same change.
It would greatly simplify my work were I able to import a CSS file from my website to the WordPress blog. Is this supported?
The blog I need help with is pithagora.com.
