Common Accessibility Issues & How to Fix Them
Learn about the most frequent accessibility problems and their solutions
Missing Alt Text
Images without alternative text are not accessible to screen reader users.
Add descriptive alt text to all images using the alt attribute. For decorative images, use alt="".
Color Contrast
Insufficient contrast between text and background makes content difficult to read.
Ensure text has a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.
Missing Form Labels
Form fields without proper labels are difficult for screen reader users to understand and navigate.
Associate each form input with a label element using the for attribute, or use aria-label/aria-labelledby.
Keyboard Navigation
Elements that can't be accessed using a keyboard exclude users who can't use a mouse.
Ensure all interactive elements can be reached and operated with the Tab, Enter, Space, and Arrow keys.
Heading Structure
Improper heading structure makes navigation difficult for screen reader users.
Use semantic headings (h1-h6) in a logical hierarchy without skipping levels. Each page should have one h1.
