I found this particular article instrumental in building my understanding of CSS's flexbox feature, which largely replaces decades worth of ugly, nasty positioning hacks with a handful of simple definitions: https://css-tricks.com/snippets/css/a-guide-to-flexbox/ https://css-tricks.com/snippets/css/a-guide-to-flexbox/ Beyond that, the only advice I can give when starting out is to avoid inline "style=" attributes like the plague, and figure out how you want to organize your elements, styles, and classes. This is the trickiest part to get a feel for, and there's no substitute for practice. Frameworks like bootstrap and semantic ui make for especially good starting points, giving you a collection of opt-in helper classes for the basics, letting you focus on adding whatever custom stuff you need for your site without implementing a ton of extra boilerplate. You don't need to use them, but they can help you get a v0.96 built very quickly during your prototype stage, and they're battle-hardened enough to be used in the wild if you decide you like their opinions.
