File Text is Yellow, cannot refresh?


I am taking a php course on Udemy, and using MAMP as a local server. Some of the files/folders are yellow, and when I edit in them I cannot refresh them in the browser, but I can refresh the ones that are white. I’m not sure what this means.



The colors represent the Git status of a file (or file contained in a directory) - orange means modified, green means a new file, etc:

Why the modified/orange files aren’t refreshing in your browser when using MAMP though I’m not sure - if you commit your work (the files/directories should turn grey once they’re committed), do those changes show up in your browser?
