Reducing the space between full width sections

There are 2 helper classes  to  reduce the space between fullwidth sections:

• pul-top
• pull-btm

<div class="is-fullwidth bg-section rel h-100 is-parallax is--flex pull-top" 
...

<div class="is-fullwidth bg-section rel h-100 is-parallax is--flex pull-btm" 
...

In default fullwidth Jimdo images you need to use the button "Alternative text & caption"

There are some additional helper classes in CSS  that can be used only for Widget/HTML:

/* pull margins */
.pull-top-10 {
   margin-top:-10px!important;
}

.pull-top-20 {
   margin-top:-20px!important;
}

.pull-top-30 {
   margin-top:-30px!important;
}

.pull-top-40 {
   margin-top:-40px!important;
}

.pull-top-50 {
   margin-top:-50px!important;
}

.pull-btm-10 {
   margin-bottom:-10px!important;
}

.pull-btm-20 {
   margin-bottom:-20px!important;
}

.pull-btm-30 {
   margin-bottom:-30px!important;
}

.pull-btm-40 {
   margin-bottom:-40px!important;
}

.pull-btm-50 {
   margin-bottom:-50px!important;
}
