I used Codecademy to learn HTML and CSS essentials. Once you have that down, you'll want to learn a responsive grid CSS framework like Bootstrap or Materialize. Then learn some basic javascript to make the page behave in cool ways (making elements appear/disappear, scroll and animate, etc). I recommend learning jQuery for that (a javascript library) but avoid any bloated frameworks like React or Angular when you're first starting out.

Once you understand those three foundational concepts (basic HTML/CSS, a CSS framework, basic javascript) try just building some websites from scratch or editing templates to make them look how you want. It'll be tough at first but you'll gradually get the hang of it!
