In a Flow page, the height of a Section is set by the height of the content it contains by default. You can override that default height, though, and tell the Section to behave as if its height is a ratio based on the height of the browser window it’s being viewed within. Along with that height setting, you can set the content within the Section to align within the Section’s new height. It’s a great design idea for creating a dramatic full-height Section on your page.
In this lesson we’ll set a Section to be the full height of the browser window and the content within it to align at the bottom of that height.
