Hi Alessandro,
Thank you for writing in, please navigate to Theme Options > CSS and remove that block below.
@media (min-width: 1170px) {
.site {
padding-left: calc((50vw - (1170px / 2)) + 1em);
padding-right: 3em;
}
}
.site {
padding-top: 1.75em;
}
These are the CSS rules that responsible for creating that left-side area. But please note that left-side area plays a big part in the Lawyer Demo, a lot of sections will be affected on the page if you remove that. You might want to remove all the custom CSS that comes with the Lawyer Demo and start with a clean slate.
Cheers!
