Hi there,
please add this code below to your css/custom.css and change the padding to your px you want.

.main-outer, .top-a-outer, .footer-a-outer, .top-b-outer, .top-c-outer, .top-d-outer, .bottom-a-outer, .bottom-b-outer, .bottom-c-outer, .bottom-d-outer {
padding: 60px 0;
}

Where is located

css/custom.css

?

Hi again, sorry here is the instruction

Hi dear, thanks for help, but not work, I create a new file custom.css. Paste your code ( www.residencealparadiso.it/Lampedusa/custom.jpg ), set padding to 20px, but margin not reduce.

Please disable all compression tools and delete your Browser cache.
Or try this code with an "important"

.main-outer, .top-a-outer, .footer-a-outer, .top-b-outer, .top-c-outer, .top-d-outer, .bottom-a-outer, .bottom-b-outer, .bottom-c-outer, .bottom-d-outer {
padding: 20px 0; !important
}
