Hi,
As every content of the page is placed inside the <body>
tag, you should be able to add border that encloses the whole site by adding this CSS:
body:before {
border: 2px solid red;
content: "";
width: 100vw;
height: 100vh;
display: block;
position: fixed;
z-index: 99999;
}
This adds a fixed border that stays within the viewport. If you want the border to span through to the content height, change the height to 100%
instead of 100vh
