 Chapter 10. Customizing the Visual Design of the Backend
 ========================================================

+The current version of EasyAdmin doesn't support the concept of themes.
+However, you can customize lots of options related to the visual design of your
+backend. All these options are defined under the global `design` option:
 
 ```yaml

-    assets:
-        css:
-            - 'bundles/app/css/admin1.css'

+
+Adding Custom Web Assets
+------------------------

+Use the `assets` option to define the web assets (CSS and JavaScript files)
+that should be loaded in the backend layout:
