# Mobile UI styles

UI styles define the font and background color of fields in your applets.

You can associate one or more UI styles to a legacy card record to change the appearance of the fields in that legacy card. Each UI style applies to a single table. You and only applies under conditions you set within the UI style record.

**Note:** Mobile UI styles can only be applied to legacy cards.

## Create UI Styles

Create and modify your UI Styles using the Mobile App Builder. In a UI style, you select a field from your selected table, and define a font and background color for that field. Use may include conditions to determine when a style is applied. For example, you may want to use a colored background on the **Priority** field to highlight when a record is high priority.

Each UI style record defines the colors for a single field, however multiple UI styles can be added to a legacy card to customize the appearance of multiple fields.
