Editing widget colours, backgrounds and borders in Fluid UI

The background and border properties menu is used to set the non-text properties of a widget, including:

  • Background color (flat or gradient)
  • Border color (if the widget has no border, increase the border size and then you can give it a color)

  • Background opacity
  • Border size and radius
  • The width and height of the widget (exact pixels)

Tip: Use the background and border icons to toggle between color editing and all of the other editing options.
