When assigning alternative text to actionable icon fonts (buttons or links), which technique is most effective?

• A. Add aria-label to the button or link
• B. Add hidden text using CSS clip
• C. Add text to an alt attribute in a surrounding span element
• D. Use title attribute instead

Answer: (A)

Assigning alternative text to actionable icon fonts effectively ensures that users with visual impairments or those relying on screen readers can understand the purpose of the icons. Using an aria-label on the button or link is the most effective technique in this context because it explicitly provides a textual description of what the icon represents or its function. The aria-label attribute allows developers to add a descriptive label directly to an interactive element, enhancing accessibility without altering the visual presentation of the icon. Screen readers can interpret this label and communicate it to users, allowing them to navigate the interface efficiently. Other techniques, such as using hidden text with CSS clip, may visually hide the text from sighted users while still being accessible to screen readers; however, they can introduce complexity in terms of maintenance and may not be as straightforward or universally supported as aria-label. Adding text to an alt attribute in a surrounding span may also be ineffective, as the alt attribute is primarily intended for images, not icon fonts used as buttons or links. The title attribute offers additional information on hover but is not consistently announced by screen readers, making it a less reliable solution for conveying essential context about the purpose of actionable elements.
