# Styles

## Element type 

Select a type from the dropdown, such as Alert, Group, or Repeating Group, to return the existing styles for that element. 

## Search by name

Type the name of an existing style, such as "Standard Alert," to find and edit that style.

## Apply theme

Add a visual identity to your application. Choose from Standard, Dark Theme, Twitter Bootstrap, Material Design, TODC Bootstrap, or Dark, Flat, or Rounded UI. Choosing one of these themes will overwrite your app's predefined styles with different colors and angles. 

## Add style

Add a custom style to your application. Choose a name and element type, such as "Custom Alert" for "Alerts." Once you define this style's properties, you can apply this style throughout your app in that element's property editor.

## Find all elements using this style 

Access a shortcut to the App Search Tool, which will return a list of any elements currently using this style. Clicking on a result in the App Search Tool will take you to the location of that styled element in your application. 

## Make this style the default 

Any new elements of this type will automatically be created with this style, rather than the predefined styles that come with your application.

## Remove this style as the default

Any new elements of this type will no longer be created with this style. Unless you set another default for this element type, new elements will not have a style when created.
