It’s important to ensure that any images used in your theme are optimized for web use so they don’t slow down page load times. Additionally, it’s best practice to use high-quality images so they appear crisp and clear on all devices.

Creating Custom CSS Styles for Your Theme

Simple Themes Plugin allows you to create custom CSS styles to further customize the look and feel of your Jenkins instance. This can include changes to font styles, button colors, and more.

button { background-color: #FF5733;

color: white; padding: 10px 20px; } “`

When creating custom CSS styles, it’s important to test them thoroughly across different browsers and devices to ensure they display correctly for all users. You should also consider any accessibility guidelines when making changes that may impact user experience for those with disabilities.
