Lost my code -- can I get it back?

I worked on the HTML/CSS project “Technical Documentation Page” for several days. Then I rebooted my computer. When I re-loaded FCC, my code was gone. Yes, I was logged in. No, I don’t believe I clicked the “Save Code” button I just found at the bottom left of the screen – but I don’t remember clicking that on any of my other projects, and they still exist.

Is there any way to recover my code?

There are two different types of saved progress for Free Code Camp: your profile and your browser cache.

A list of your completed challenges is saved to your account in the FCC database. You can see the list of completed challenges by looking at your public portfolio. With a growing curriculum already over 1,400 lessons and a community of millions of people, FCC does not store every solution to every challenge in its database. There are some challenges which are classified as projects required for certifications. Your solutions to those can be viewed on your settings page.

Your in-editor code is saved in your browser’s local storage. Recent in-progress code from the challenge editor is also saved in your local browser cache when you run tests. If you are completing lessons and do not see your recent code, then your local storage has been cleared or something is preventing FCC from writing to your browser’s storage. This could be a browser setting, a privacy extension, or a browser version incompatibility. Especially as you get to more complicated challenges that may take multiple sessions, I strongly recommend saving your in-progress work outside of the browser cache.

This is a good opportunity to learn the ins and outs of your GitHub account, but you can also just save locally or use a service like repl.it which allows for versioning.
