Rauno Freiberg (designer at Vercel) shares his web guidelines for web interfaces. A few that stood out for me:

Inputs should be wrapped with a <form> to submit by pressing Enter

Interactive elements should disable user-select for inner content

Actions that are frequent and low in novelty should avoid extraneous animations

Read them all on Rauno's (beautiful) website, and check out the Craft section while you're there.
