What does ADA stand for?
Americans with Disabilities Act
American Disabilities Assistance
Accessibility Development Act
American Disability Association
The ADA is a landmark civil rights law known as the Americans with Disabilities Act. It prohibits discrimination against individuals with disabilities in many areas including digital access.
Which HTML attribute provides alternative text for images to assistive technologies?
aria-label
title
caption
alt
The alt attribute on an ![]()
tag offers a text alternative for screen readers. It ensures users who cannot see the image still understand its purpose.
Which WCAG principle ensures that content must be presentable in ways users can perceive?
Robust
Perceivable
Operable
Understandable
Perceivable is one of the four POUR principles in WCAG. It requires that information and user interface components be presented in ways users can perceive.
Which guideline series is commonly referenced for web accessibility compliance under the ADA?
WCAG
ISO 9001
HTML5 Specification
Section 504
The Web Content Accessibility Guidelines (WCAG) provide technical standards widely adopted for ADA digital compliance. They outline how to make web content accessible to people with disabilities.
What practice ensures interactive elements can be used without a mouse?
Voice commands only
Hover-triggered menus
Mouse-only drag and drop
Ensuring keyboard accessibility via Tab navigation
Keyboard accessibility ensures all interactive page elements can be reached and activated using the keyboard alone. It is crucial for users who cannot use a mouse.
What is the minimum WCAG conformance level typically required to meet ADA Title III compliance for websites?
WCAG 2.1 AA
WCAG 2.1 AAA
WCAG 2.1 A
No specific level
Legal guidance and many court rulings reference WCAG 2.1 Level AA as the benchmark for ADA Title III compliance. It balances accessibility requirements with technical feasibility.
If a form input lacks a visible label or programmatic label, what barrier does this create?
It prevents keyboard navigation
It causes the page to crash
Screen readers cannot identify the purpose of the field
It disables CSS styling
Without a properly associated label, assistive technologies cannot announce what the form control is for. This makes it impossible for users with disabilities to complete the form correctly.
Under WCAG 2.1 Level AA, what is the minimum contrast ratio required for normal text?
7:1
4.5:1
2:1
3:1
WCAG 2.1 Level AA specifies a contrast ratio of at least 4.5:1 for standard text to ensure readability by users with low vision.
Which ARIA attribute should be used to announce dynamic content updates to screen reader users?
aria-label
aria-live
aria-hidden
aria-checked
The aria-live attribute designates regions that may change dynamically. Screen readers monitor these regions and announce updates to users.
What is a key step to make a PDF document accessible?
Flatten all layers
Embed high-resolution images
Encrypt the PDF
Add proper tags and reading order
Accessible PDFs require a hierarchical tag structure and logical reading order so screen readers can interpret the content correctly.
Why is using semantic HTML important for accessibility?
It reduces server load
It enables assistive technologies to understand page structure
It increases image resolution
It automatically corrects grammar
Semantic tags such as ,
When should you provide a text transcript for audio content on a website?
For decorative images
For CSS background music
For video content with captions
For audio-only materials
Audio-only content requires a text transcript so users who cannot hear can access the spoken information. Videos with captions need captions, not transcripts alone.
What is the purpose of a "skip to content" link in web accessibility?
It hides content from visual users
It improves search engine optimization
It locks focus on the header
It allows keyboard and screen reader users to bypass repetitive navigation
Skip links let users jump straight to the main content, saving time for those who navigate sequentially with keyboards or screen readers. This avoids repeated navigation menus.
Under WCAG 2.1 AA, what is the minimum contrast ratio required for large-scale text (at least 18pt or 14pt bold)?
2:1
4.5:1
7:1
3:1
WCAG 2.1 AA permits a lower contrast ratio of 3:1 for large-scale text because larger characters are inherently easier to read. Regular text still requires 4.5:1.
Which WCAG principle focuses on ensuring that content appears and operates in predictable ways?
Operable
Perceivable
Robust
Understandable
The Understandable principle requires that users can predict how content and controls will behave. Predictability reduces confusion, particularly for users with cognitive disabilities.
Which ARIA attribute indicates that a form control value does not conform to the expected format?
aria-checked="false"
aria-invalid="true"
aria-required="true"
aria-hidden="true"
The aria-invalid attribute, when set to true, informs assistive technologies that the field's value is invalid and needs correction. This improves form validation feedback.
If you want to notify assistive technologies of non-critical updates without interrupting users, which aria-live setting should you use?
rude
off
polite
assertive
The aria-live="polite" value queues updates and announces them at the next available opportunity without disrupting the user's current task. Assertive would interrupt immediately.
To ensure content remains legible when zoomed to 400%, which CSS practice is most effective?
Use relative units like em or rem for layout and typography
Fix element sizes in pixels
Use absolute positioning for all elements
Disable zoom scaling
Relative units such as em or rem allow text and layout to scale proportionally during zoom. Fixed pixel dimensions can break layouts and reduce readability at high zoom levels.
