For example, I use the css -webkit-rounded-corners attribute to create rounded corners in diffs.


To enable the Web Inspector in the GitX HTML views, run the following command in a terminal window. You can now right click in the web views and select ‘Inspect Element’ to open the Web Inspector. Web Inspector allows you to browse the DOM, inspect CSS, and evaluate JavaScript expressions.
