How to customize your CSS.
This is my first time so please bear with me.
1. Go to Journal Style
2. In the search bar right above the selection of journal styles, type Flexible squares.
(You can choose any of those styles as long as it is flexible squares.)
3. After choosing s theme from flexible square, go to 'Customize your theme'.
4. Then go to Custom CSS.
5. Choose 'NO' in every scroll bar there. (Me: I do not know what you call it.)
6. Copy paste the code in the Custom Stylesheet panel.
And that's it. You have a customized journal.:D
