Customizing Jenkins UI with Custom CSS and Themes

If you are dissatisfied with the default Jenkins UI fonts and icons, you can give Jenkins a fresh look using custom CSS styles with a custom logo, which makes the interface more visually appealing.

Key features of the custom CSS:

Flat UI fonts

Improved syntax highlighting for Shell blocks

Better highlighting of console output Preparation

First, install the simple theme plugin, then restart Jenkins. Navigate to Manage Jenkins → Manage Plugins, click the available tab, search for simple theme, and install it.
