The Styles Tab manages collections of visual properties that are shared across elements in the app. Styles make it easy to maintain and modify a consistent visual identity. Rather than setting the font, background, and border for each element, define a style and apply it to all the elements of a given type. Bubble includes some built-in themes to help you get started. Use these to completely restyle the app. We integrate some popular themes from across the web, such as Bootstrap and Material Design.
