Frequently asked questions
Do decorative images need alt text?
Give purely decorative images an empty alt attribute (alt="") so screen readers skip them. Meaningful images need a short description.
Should I lazy-load every image?
No. Lazy-load images below the fold, but load the main hero image normally so it appears quickly.
