Alignment organizes the various elements on your page and presents a structured and coherent look. It cleans up the page and helps to communicate more clearly.
The concept of alignment calls for conscious decisions about where you place items on the page. Don’t ever stick something on the page in some random spot! Every item needs to be connected to something else on that individual slide, and your collection of slides should have consistent alignments throughout the deck. No more sticking things in empty corners—make sure elements are aligned.
