Jacober Nielsen, a famous American website design engineer, pointed out in his study of the eye trajectory that most people involuntarily read Web pages in an "F" letter-shaped pattern, which is a basic constant habit, consisting mainly of the following three aspects
First, the reader's eyes are first horizontal movement, often swept through the top half of the content of the Web page, thus forming a transverse trajectory of motion. This is the first horizontal line of the F letter.
Second, the reader looks down, and the typical scan is a shorter area than the first step. This long formed the second horizontal line of F.
Third, readers scan the left part of the page vertically. Sometimes the action is slow and systematic, so it's a vertical line of F.
