This ticket is a part of #816 and will be used for creating the landing page content for Chapter 3: Global Settings and Styles.

I will draft the content for the new page in a Google Doc: https://docs.google.com/document/d/1tjGKZiBKMSuzZZ84aN_rPBQL0vEOh9SBmhx57Lyl-T8/edit?usp=sharing

A template for other landing pages

Because this will be the first chapter to go live, we should use it as a template for how each of the chapter landing pages should look. The goal for this is consistency from chapter to chapter so that readers know what to expect.

Reference to the outline for what chapter landing pages should accomplish: https://docs.google.com/document/d/1w1P7j8nX2AsibExh70pX7Y-248XTTdWj7YNkMgMGOyw/edit?usp=sharing
