Installing themes on Chrome is easy. You just find a theme on the Chrome Web Store and download it. But what if you have a theme that’s NOT from the Chrome Web Store? Well, you can read this!!!!!
Before you do anything, you must extract the ZIP. Most modern operating systems have a ZIP extractor, so all you need to do is double-click the file and then click Extract. Drag the files that come out into a new folder.
Now comes the fun part. Open a new tab in Chrome and type chrome://extensionsNow, you must toggle Developer mode ON, and click Load Unpacked. Your interface will look different to mine if you haven’t enabled Material Design in Chrome. A small File browser will open. Find your folder and double-click it. For some reason, my screenshot app wasn’t working right, and I can’t show myself doing it. But, once you do it, your theme will instantly be installed!Doesn’t that look so much better (BTW I made this myself!)?
