    Quick answer#

    Add a CSS selector like #pricing-table and Lemwatch captures and diffs only that element — perfect for pricing, hero copy, or CTA buttons.

    What it does#

  1. Renders the full page, then screenshots only the matched element
  2. Runs pixel + text diff on that element alone
  3. Ignores everything else (nav, footer, ads) automatically
  4. Where to find it in Lemwatch#

    Visual Monitoring → [page] → Advanced → CSS selector.

    How to set it up#

  5. Right-click the element in your browser → Inspect.
  6. Copy a stable selector (prefer id over long div > div chains).
  7. Paste it into the CSS selector field.
  8. Click Test selector — Lemwatch highlights what it matched.
  9. Save. Next capture is scoped to that element only.
  10. FAQ#

    What if the selector matches nothing?#

    The run fails with "selector not found." Fix the selector or Lemwatch skips the run.

    Can I watch multiple elements?#

    One selector per page. To watch two elements, add the page twice with different selectors.
