Install the plugin and drag the "Best Rich Text Input" element onto your page.
In the element's "Appearance" tab, you will find the new color customization fields:

Toolbar Bg Color: Sets the background color of the toolbar (e.g., #FFFFFF or transparent).

Toolbar Border Color: Sets the border line color of the toolbar.

Icon Color: Sets the default color of the formatting icons.

Icon Active Color: Sets the color of the icons when you hover over them or when a formatting option (like Bold) is active.

Placeholder Color: Sets the color of the placeholder text when the editor is empty.

To change the background color of the typing area itself, simply use Bubble's native "Background style" settings in the Appearance tab.

Choose the desired amount of formatting tools in the "Style Complexity" dropdown (Basic, Medium, or Full).

The typed content can be saved to your database by referencing Best Rich Text Input's value, or by setting up Autobinding directly on the element.
