# Responsive design

Use the **Progression** feature to fine-tune how your text appears across different devices. This ensures optimal readability whether your content is viewed on desktop, tablet, or mobile screens.

Adjust the following typography parameters for every style for each screen size:

* Font size
* Line spacing
* Space between (for Lists only)
