You can create themes or customize existing themes.

## Vorbereitungen

Role required: admin

## Prozedur

1. Navigate to AllSystem UIThemes.
2. Choose from the following options.
   * To create a new theme, click New.
   * To customize an existing theme, click the theme name.
   {#t_CreateOrCustomizeATheme__choices_nnv_xn2_kyb}
3. Enter a name for the theme in the Name field.
4. Add any of the [default CSS
   styles](https://servicenow-prod.fluidtopics.net/hBAt9FGeGrsyfcsuVRFSYg "You can use CSS styles to control the appearance of elements in a theme.") in the CSS field.  
   Sometimes the default style is not the only style definition for an object. In such cases, you can use the CSS [important rule](http://www.w3.org/TR/CSS2/cascade.html#important-rules) format to override any other style definitions with the default definition. For example, this definition overrides the text color in the main navigation: `$navpage-nav-color-sub: #fff
   !important`.
5. Select the Active check box.
6. Select one of the following from the Device choice list to identify the user interface version for the theme.

   | Option | Description |
   | Browser | Identifies a Legacy UI11 theme. |
   | Doctype | Identifies a Legacy UI15 theme. |
   | Concourse | Identifies a Core UI theme. |
   |-|-|

   {#t_CreateOrCustomizeATheme__choicetable_zdm_5jm_zq}
