Frequently Asked Questions
What is alt text and why is it important?
Alt text is a text description added to images in HTML. It's essential for accessibility because screen readers read it aloud to visually impaired users, and it appears when images fail to load.
How long should alt text be?
Alt text should typically be under 125 characters. Some screen readers cut off at this length. For complex images, use a longer description in surrounding text.
When should I use empty alt text?
Use empty alt text (alt="") for purely decorative images that don't convey information. This tells screen readers to skip the image.
What's the difference between alt text and captions?
Alt text is hidden in HTML and read by screen readers. Captions are visible text displayed below images for all users. Both serve different purposes.
