 By default, any changes you made in DevTools are not safe. These changes will go after a page is reloaded. However, with Workspace, we can change that. We can start setting up a workspace by dragging the source folder into the Sources panel. Alternatively, we can add it in the File System tab. Click Allow in the Prompt to give DevTools permission to read and write to the directory. Alright, let's try to make some changes in the index.html and save it with the Command-S or Control-S shortcuts. Next, change the color in CSS to Rebecca Purple and edit the log message in our script. Click on the Grid button to check our new log. All the changes we just did in DevTools work in the browser even after the page load because these changes are safe in our source code. You could even open your code editor to double-check.
