I have a problem with the margins of the layout structure. It leaves a large space at the bottom of the top of the page which leaves excessive space between the top and the text. See the print. Another problem is that when I edit anything like font color or hover or spacing in the theme options it disconfigures the entire Home css, loses the font formatting, etc. I had to go back to several backups.

Can you help me?
