I want to reduce the extra space in footer, attached screenshot, marked in RED is the extra space which we want to reduce.
please let us know the steps how to achieve it.
I have been doing the setting through HTML block as mentioned somehow it’s not reflecting properly, is there any other way to achieve this apart from HTML block.
You can try assigning an extra class to the rows of the HTML block that you have used then targeting the class you can set the margins with Custom CSS.
