Decide if you want to do front-end or back-end or both. Front-end is what the user visually sees on the screen and involves HTML, CSS, Photoshop and perhaps a bit of Javascript. No processing is done in front-end. Back-end is what happens on the server and which processes input and output. The user does not see this but interacts with it. Back-end is most often written in PHP, ASP or Java (not Javascript). It often also involves connecting to and using a database so at least basic knowledge of SQL is required.
