Hi Pratik Sharma, Thank you for your support ๐ yes, you are correct, For example: If you have 3 h1 elements the counter will be like 1 h1... 2h1... 3h1. Use case: If you have 10 h1 elements and you put a counter number(1 to 10) at the starting of each heading. If you want to include a new heading between any of the elements, you have to manually enter a counter number again. But this counter-increment property will reset the numbers automatically.
