# Component variables > **Info:** This is release candidate documentation for **Stream Chat Angular SDK v8**. For the latest stable version, see the [latest version (v7)](https://getstream.io/chat/docs/sdk/angular/). CSS variables are the easiest way to customize the theme. The variables are organized into two layers: - Global - Component Global variables change the layout/look-and-feel of the whole chat UI, meanwhile component variables change only a part of it (for example message component). Component variables can be further grouped in the following ways: - **Theme variables** for changing text and background colors, borders and shadows - **Layout variables** defined for some components (but not all) to change the size of a specific part of a component You can find the list of components below: | Component name | Variables | | ----------------------------------------- |
