@twisted1919,
so these margins are fixed and we can't change margin or padding of blocks?
can we make margins 0 so there is no space between 3 blocks and if some one need space they can put padding or enter key.
Like i try to create nice email but this big space is really not looking good.
Thanks
This is not an issue, this is how builder it's working, to remove extra space simply after you build your template you can remove padding from your tables adding some custom css.
For example just by changing the padding of the tables you will significantly reduce the space between the blocks.
