# Adblock Element Hiding
If your cookie consent banner has class `.cookie-banner` or ID `#consent-popup`, adblockers may hide it — users never see the consent notice, which can cause GDPR compliance issues and broken UX for ~30-40% of desktop users.
## Quick Reference
- Adblockers use EasyList filter rules to hide elements with class names, IDs, or patterns associated with ads
- Common blocked names: `.ad`, `.ads`, `.advertisement`, `.banner`, `#ad`, `#ads`, `#banner`, `.sponsor`
- Affected elements: legitimate banners, notification bars, promotional sections, and cookie consent notices
- Test your site with uBlock Origin enabled — check for missing content, broken layouts, or hidden consent banners
- Rename affected elements using semantic, content-specific class names to avoid false-positive blocking
