You can easily add a border around your site in Semplice, like this one:
Adding the code
To add a border around your whole site, go to Customize > Advanced> Custom CSS > Edit Custom CSS and add this code:
.sections {
border-right: 10px solid #000;
border-left: 10px solid #000;
border-bottom: 10px solid #000;
}
header {
border-right: 10px solid #000;
border-left: 10px solid #000;
border-top: 10px solid #000;
}
div#overlay-menu { border: 10px solid #000; }
div#overlay-menu header { border: 0; }
Change all of CSS settings to your liking, and you're done!
