	~~==Design considerations==~~		For more about blindness, go to [https://accessibility.perpendicularangel.com/what-is-accessibility/types-of-disabilities/visual-disabilities/blindness/ Blindness] on [[Perpendicular Angel]].
	* All content must be present in text or in a text equivalent, because screen readers can't read non-text content.
	* All functionality must be available using only a keyboard, because while most blind users can physically move a mouse or trackpad, they can't see where the pointer is.
	* Semantic HTML is key, because screen readers offer blind users the ability to navigate by headings, landmarks, and other semantic elements, and also uses those elements to describe what the user is focusing on.
	* Custom controls must have the correct name, role, and value, and must change that value when appropriate, so that blind users can understand what is going on.
	* Users must receive immediate feedback after all actions, because if the browser is silent, the user doesn't know if what they did had any effect.
	* Videos must have audio descriptions if the current audio doesn't describe what's going on in the video -- anything that's purely visual content must be described.
	* Touchscreens (primarily on mobile devices) use swipe actions to control the screen reader, so custom swipe actions generally won't work (or will break the screen reader). Similarly, all features require a click action to work.

	~~Source: [[Deque University]] accessibility training.~~

	~~When we design for people with vision impairment we provide:~~

	* The ability to enlarge and reduce text size and images
	* The ability to communicate the meaning of visual content - pictures, charts, and icons - through a method other than visual display
	* The ability to customize fonts, colors, and spacing
	* Properly-tagged semantic HTML understood by a screen reader or text-to-speech software
	* Audo descriptions of video in multimedia
	* The ability to use a Braille reader
	* Forms and data tables where the information is easy to scan and understand even at 400x zoom
	* Color palettes and iconography that is compatible with colorblind vision
	* Content that always relies on more ~~than just color to communicate meaning~~
	* Keyboard navigation

	It's also important to recognize that someone with a visual disability may not know when a new window or browser tab is being opened. Not opening new windows by 30 Days to a More Accessible Website explains more.
