Bootstrap 5.3 Content

Bootstrap provides typography, image, table, and other content styles built on top of Reboot, a normalized baseline.

Reboot

Bootstrap Reboot normalizes default browser styles for consistent cross-browser rendering. It provides a foundation for the typography and content styles that follow.
