Hmm, Well I wouldn't say you need to know things by heart, but getting acquainted with your options and their capabilities, then looking them up when you need them specifically is plenty (e.g. Knowing you can use CSS animations to rotate an element on hover, and then referencing w3schools.com for the specifics).
And for how to start working on a page. In a professional setting we have our UI/UX folks who'll decide how things should look like and hand us a photoshop file + additional resources we need (like logos, icons, etc). But when I'm working on a personal project, I start by sketching out a wireframe (I personally recommend Realtimeboard for that), and once my entire layout is looking goods I'll look around other websites for inspiration on specific styles (or if i'm feeling lazy I'll use a pre-made library like Bootstrap or MaterialUI).
I feel like this could change depending on each person though, so take all my advice with a grain of salt
