If you want to change some CSS, you can create a new component easily through the UI.
- Go to Admin → Customize
- Click on
Install
- Then choose
Create New
. The type should beComponent
.
That’s it! Attach it to your theme; then, you can Edit CSS/HTML
.
You would usually want to fork either if you want to contribute to the original component on Github (by creating a Pull Request) or if you want to create your version. If you do that, you won’t receive any updates from the original component; that’s probably not what you want here!
