I need to remove vertical lines from my mobile view

.vl {
  display: block;
  border-right: 1px solid #181010; 
  height: 800px; 
  position: absolute;
  left: 50%;
}

[data-section-id="6120918a0dd1f30d38351f02"] .content-wrapper {
    padding-top: 0 !important;
}
This is the code i used for putting vertical line between my section Now i used every code but I'm unable to remove that vertical lines from my section.

I'm not programmer now I don't know how to remove vertical line in mobile view.

Try adding to Design > Custom CSS

@media screen and (max-width:767px) {
	.vl {display: none !important;}
}
