Mobile accessibility: WCAG principles and how it improves UX (Part 1)
Principle 1: Perceivable
Small screen size
Think mobile-first before designing with the goal of creating a responsive design with minimal information (with reasonable default size for content and touch controls).
For portrait layouts, place form fields below, rather than beside, their labels.
Zoom/Magnification
The user must be able to pan horizontally and vertically and to make sure that the browser pinch zoom is unblocked and should be able to zoom the page to at least 200%.
Offer options on-screen functions to alter text size and access to OS text size settings.
Contrast
Always keep in mind that devices are used for both indoors and outdoors. It is important to keep in mind strong or faint lighting or the time of day. The correct practice of providing good contrast minimises challenges for users who have poor vision.
Non-Linear screen layouts
In a small screen set-up you can control the user’s eye-path better when information is presented from the top to bottom.
Other layouts tend to start from the middle part of the screen for a better visual experience.
