Description
Many people with cognitive disabilities have trouble tracking lines of text when a block of text is single spaced. Providing spacing between 1.5 to 2 allows them to start a new line more easily once they have finished the previous one.
Examples
Example 1: Setting the element to 1.5 line height
In the style sheet set the characteristics of the element.
body { line-height: 1.5; }
This sets the line height of everything in the body of the document to 1.5.
