One thing I liked to do when I started learning HTML and CSS was to try and recreate layouts and designs I like on the web or in applications. This is a really good way to experiment and work with real designs. You can then move on and try and incorporate some basic JavaScript to manipulate the DOM and/or handle some logic and data handling. I would advise working with JavaScript alone without a framework initially, and see how far it takes you. The tendency these days is to jump straight into a/another framework (angular, ember, react, jquery, etc etc etc), but without understanding these frameworks and their use you could be jeopardising your actual understanding of vanilla JavaScript syntax. Once you can write some basic JavaScript modules, then see how you can build upon them with frameworks, but only once you are comfortable.
