The Tabs composition consists of two elements. The main one - Tabs Content, and the navigational one - Tabs Switcher.
This is the same Tabs element you're familiar with, with two notable new additions to benefit from - Spacing & Image Options. Spacing Options give you control over the gap between the image and title, the title and the description, the description and lower title, as well as the paddings for all the text area.
When it comes to Image Options you have 2 to choose from - Fill & Fit. Choosing Fill will crop the image to fill the frame while choosing Fit will let the image keep its aspect ratio, but will resize to fit the given dimension.
