# Change background color

This guide shows how to apply a custom background color to a section using the theme editor's built-in custom CSS field.

1. In the theme editor, navigate to the section you want to edit.
2. In the settings panel, scroll to the bottom and expand **Custom CSS**.
3. To apply the change across your entire storefront instead, navigate to **Theme settings > Custom CSS**.
4. Paste the following code into the input field and replace `#000000` with your desired hex color code.

```css
section { background-color: #000000; }
```
