How to manually apply a personalization to an element
If there is a specific element you want to personalize, but you are not able to use the highlight feature, you can change what element is being personalized by adding the ‘selector’ to the personalization editing tool.
Click on the ‘Affected Elements’ tab and click ‘view / customize selector (advanced)’
Use the field provided to either adjust the selector so it is more specific, or delete the selector listed and add the selector you want to target.
Click ‘Done’ once you are ready.
Make any personalizations to the element you have selected and publish the changes.
