search What we check

Whether the first (hero) image has explicit width and height attributes to prevent layout shift.

build How to fix

  1. 1 Add width and height attributes to your hero image.
  2. 2 Example: <img src="..." width="1200" height="630">.
  3. 3 This prevents Cumulative Layout Shift (CLS) and speeds up rendering.
