Page border

I'm trying to add a full page border to my website that is responsive to changes in the size of the browser. I'm particularly having trouble getting the bottom border to stick. Any suggestions?

If you could post your code or a workspace snapshot that will help. I'm not sure exactly what you mean or how you would like it to look in the end, so seeing your site will give me a better idea of what to suggest.

Are you applying a border to your body element? By default, it will only be as high as needed to enclose the contents.

But you can expand it to fill the window this way:

body {
  margin: 0;
  height: 100vh;
  box-sizing: border-box;
}

Thank you, Steven. I had forgotten about vh. I found this solution online after I posted:

* {
    margin: 0;
    padding: 0;
}

body {
    background-color: black;
    color: white;
    cursor: pointer;
}

html, body {
    height: 100%;
}

#container {
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    border: solid gray 15px;
}

and it worked for me. Yours is much simpler and more elegant, however.
