Chapter 14. Customizing Look, Feel, and Behavior

JIRA offers a simple functionality in its UI to change the colors of various sections and elements, such as the header, footer, and links; you can also upload your custom logo. However, if you want to change the width of a certain section or the whole body element, you can't do it from the UI. It's possible to include your own custom CSS to make changes to the look and feel. It's also possible to load custom JavaScript in a JIRA instance; this enables changes in the behavior of various HTML elements. For example, you can selectively show or hide a field on another field's values and insert text-based templates in JIRA fields. In this chapter, we will take a look at such customizations.

We will cover the following topics:

• Adding your own CSS
• Adding JavaScript to show/hide field
• Velocity templates
