calculations, and applying UI styles to different UI elements.

## Mobile UI rules and actions {#mobile-ui-rules__section_gfc_hcy_lnb}

To modify the appearance of your mobile views and input form screens UI, you must create a
mobile UI rule, and at least one associated mobile UI action.

Mobile UI rules
:   A mobile UI rule applies to a single mobile view and input form screen. When you create a rule, you select a record to apply the rule to, as well as conditions that define when your rule applies.

Mobile UI rule actions
:   Each mobile UI rule uses mobile UI rule actions. These actions define the changes made to
    your target record. When you create an action, you select an operation, which defines the
    kind of change you want to make. You then define a value, which gives the rule more detail on
    the specifics of the change you're making.

For more detail on the kinds of changes you can make with mobile UI rules, see the next
section. For detailed steps on creating mobile UI rules and actions, see [Create a mobile UI rule](https://servicenow-prod.fluidtopics.net/x6hiWk5355sQNCefeTWjUg "Create a mobile UI rule to apply styling or field calculations for your mobile UI elements.").
