I used some code from Eltee-Taiwo's reposity
- Clone the reposity
- Unzip the
.zip
file - In Chrome settings, go to the Extensions tab
- Enable Developer mode
- Click Load Unpacked
- Select the unzipped folder where the
manifest.json
located
- Go to the extension's folder
- Create a
styles
folder (and open it) - Create a
.css
file whose name should be the domain of the page you want to modify
(for example: If you want to create a stylesheet for the website www.google.com, then create a filewww.google.com.css
) - Modify the file as you wish
