Hi @nimay50244411 ,
Having multiple elements share a selector is typically not good practice, especially when using the VEC. This could cause issues during content delivery and or tracking goals and settings.
For instance, if you want to change a heading for element A using the VEC and track clicks on element B when both elements share the same CSS selector: Target will not know how to differentiate between the two elements. This is why we recommend using unique IDs for elements that you would like to test or target using Target. See this article for more information.
Let me know if you have any questions!
