Force style isolation is done in some cases because sometimes a website’s CSS conflicts with the CSS of the ad format causing display challenges.

Here’s how you can do that:

  1. Log in to your Broadstreet account here https://my.broadstreetads.com.
  2. Click “Advertisers” on the left navigation bar.
  3. Select the advertiser you want to create ads for.
  4. Click “New advertisement”.
  5. Go to the “New generation” ad format.
  6. Select the “The Billboard (Beta)” ad format and click “Create a the Billboard (Beta)”.
  7. Enter the name for your advertisement.
  8. Upload the banner image for your advertisement.
  9. Enter the destination URL.
  10. Select your preferred background-color.
  11. Click “Show advanced”.
  12. Under “Style Isolation”, select “Force style isolation”.
  13. Under “Extra CSS”, enter the CSS code.
  14. Click “Create advertisement”.
