Unit 5: UI Design - 4 Flashcards
Why should we consider accessibility in web design?
Because users may have impairments (e.g., visual, auditory, mobility), be in constrained environments, or use different devices, browsers, or assistive tech.
What does W3C stand for and what does it do?
World-Wide Web Consortium; it provides web standards, specs, guidelines, tools, and promotes accessibility.
Name the 4 principles of accessibility according to WCAG 2.0.
Perceivable, Operable, Understandable, Robust.
What does Perceivable mean in WCAG?
Information must be presentable in ways users can perceive (e.g., text alternatives for images, captions for videos).
What does Operable mean in WCAG?
Interface must be usable; all functionality should work with a keyboard and not cause seizures.
What does Understandable mean in WCAG?
Content must be readable, predictable, and help users avoid and correct mistakes.
What does Robust mean in WCAG?
Content must work with current and future technologies, including assistive tech.
What HTML attribute provides alternative text for images?
alt attribute in the <img></img> tag.
Why should you avoid screen flickers and blinking on web pages?
They can cause seizures and are distracting.
Why is “click here” a bad link text for accessibility?
It’s meaningless out of context, especially for screen reader users.
How does identifying a page’s language help accessibility?
Helps screen readers pronounce content correctly and aids search engine classification.
What is the key idea behind “Beyond Accessibility”?
Accessibility alone isn’t enough—usability matters too, like convenient navigation for disabled users.
