What is "direct formatting"?

In the. release notes for Scrivener 3.1, I notice the following, but I"m not sure I understanding it. What does “direct formatting” mean?

Previously, when setting up Section Layouts for Epub 3, you had to set up styles and then apply the styles in the Section Layouts formatting area. Now you can apply font, italics, colours, font size etc directly to the Section Layouts area for Epub 3/KF8, the same as you can with other file formats.

All the best,
