Accessibility aims for inclusiveness (i.e., when one and all can use the technology irrespective of their disabilities). When designing for improving UX, following the accessibility standards should be essential.
The seven principles of accessibility include:
Design for the blind should be a priority as about 80% of the accessibility issues are associated with blindness
Assigning ALT tags for all the images and graphical content is important
Tag hamburger icons so that the screen readers can find them easily and can navigate across touchpoints
Place the most important content and options at the top for easy accessibility
Test for accessibility with real users facing accessibility issues
Do not disable the zoom functionality when designing for mobile
Design for accessibility from early on. This saves time, money, and efforts.
