I am trying to use the CSS tab of the UI Theme Designer and noticed a lot of the elements have, what appear to be, custom defined classes. Based off of my knowledge of the Bootstrap and Jquery UI API's I believe this classes are doing some "behind the scenes" styling of the elements they are applied to. Is there anywhere I can find the CSS source code that is used for the Fiori Launchpad? Although I have been able to make nearly all the changes to the CSS styling I have tried, once I start getting into much more specific styling I have been running it a problem of being able to make changes of any kind to certain elements.
If anyone else has been facing this issue and found a solution that doesn't include the CSS source code, please share too! 😊
