Setting question

Hi, how can I get the following setting for seeing the code change as I work on it?freecodecamp

That is the old interface, and if you’re referring to the lower left, it didn’t change as you worked in it, that is the results of running the tests, and works the same on the current interface as it did then.

If you just mean the colour of the interface where you type your code in, again that is the old interface, but you can install browser scripts to change the look of the current interface - if you search the forums there are several threads on this subject with links
