In many sections, there's an option to animate the text. The sections that offer this are:
Image grid with text
Image with text
There are two options for text animation as well as an option for "None". Both animation options are triggered with the section comes into view in screen.
Each block of copy or buttons in the section will animate in with a fade one after each other, from top to bottom.
All of the copy in that section will animate in at with a fade at once.
