1.4.5 Images of Text
Make it easier for users to see and hear content including separating foreground from background.

About

Use plain text instead of using images to display text, because screen readers cannot read text inside an image and text inside images cannot be resized by browsers when a user chooses to use larger fonts.

Example:

Before Rectification

image of displaying text inside an image

After Rectification

image of displaying text in a plain text area
