# Form styles and component styles
## Adding CSS styles in the application
After clicking the button in the left sidebar menu **Application style**  a side panel with the embedded CSS sheet editor for the application will slide out. The button **Application style** is visible only in the editor **Application**.
Figure 1. Application style editing panel
The CSS editor offers:
* CSS syntax highlighting and autocomplete,
* text search,
* basic CSS validity checking,
* automatic refresh of the application after each CSS definition change.
The created style is applied by entering its name in the field **Style names** available in the section **Styling** panel **Properties**.
## Component styling and platform styles
Base components can be assigned styles defined on the platform or styles created in the application. Their names should be added in the panel **Properties** → section **Styling** → **Style names** (additional styles are added by pressing the Enter key).

When adding a platform style, we get a list of style suggestions available for the given component.
