Course Recommendations

Hi,

I’m looking for recommendations of courses to expand my knowledge. A few years ago I did a beginners course in WP, but since then my job role has expanded and I now oversee 2 websites. (One of which needs a lot of work/rebuilding)

I’m thinking I need to increase my CSS knowledge and my knowledge of HTML is basic. What should I be looking to learn?

I’d prefer classroom learning, but understand that might not be readily available at the moment.

Many thanks
