The obligatory first post anxiety. Scary stuff. Anyhow, I'm going to just list a few sites that I have used and found helpful in web development. Firstly there is the amazing W3 Schools https://www.w3schools.com/ . They have references, tutorials, examples, and an editor that let's you try things and see live changes to your code right on their site. Very hand. Secondly there is Pexels https://www.pexels.com/ . They have hundreds of great photos that can be used on websites for free.
Keeping track of things I learn during my web development course
