Hello,
I looked at your site and found some simple CSS you can add to the Customizer to remove the white space.
Start by navigating to Appearance > Customize > Advanced > Custom JS & CSS
Paste this code in the CSS box at the top:
.site-content {
padding-top: 0px;
}
.entry-content {
margin: 0;
}
I did notice on the FAQ page the very first block has top margin on it, which is causing an even bigger gap on that page. You will need to go into the page itself and remove the margin-top from that block. You may have to go into text view to remove it:
margin-top: 50px;
should be removed from the first div on the page.
Please let me know if you have any other questions,
Nicole
