⇱ Filter Sizes Dynamically with Labels for Header Bidding

Filter Sizes Dynamically with Labels

About this example:

  • This example demonstrates dynamic filtering on ad unit sizes
  • Ad unit labels applied based on CSS media queries
This example uses a test version of Prebid.js hosted on our CDN that is not recommended for production use.
