Custom CSS
You can add Custom Cascade Style Sheets (CSS) to the mashups that allow you to modify the interface, layout and presentation without changing the mashup. The typical usages of Custom CSS are as follows:
Responsive UI — Specifies relative positions and dimensions (width/height), Media Queries, Flexboxes and other standard containers.
Animations — Works for any standard CSS key frame.
Detailed Decorations — Displays shadow, color, font, border in a window.
Customizations — Helps to modify the user interface without changing the mashup.
