Being able to change not just a site's text size but also its text spacing can be helpful to people with different disabilities. People with a variety of print disabilities (including low vision, dyslexia, other cognitive disabilities) can benefit from being able to increase the spacing between lines, words, and/or letters on their own device. When spacing is increased, the content should not become less readable, or unreadable, due to content overlapping or being completely hidden.
