How can I minimize the space between blocks?

Could you please tell us which block you are referring to? I tested the form 81772753410355 and I didn't notice any gaps between fields. Are you referring to space above the paragraph marked in the screenshot below?

You can reduce the space by adding the following custom CSS code:

#cid_10{

  padding-bottom: 0px;

}

#id_12{

  padding-top: 0px;

}

Along with the code above you can also add this code if you wish to decrease more space:

.form-header-group{

  margin-bottom: 0px;

}

Exactly the space is too big between blocks, I will try the CSS tomorrow and will let you know.
Kind regards,
