How did you make your sidebar on your Neocities follow down the page like that?

there’s a div called “sidebar” that includes both the picture and the buttons. i added this in the css

.sidebar {
width: 200px;
float: left;
position: sticky;
top: 0;
}

not sure if it’d work in every instance, i’m not super good at html, but it worked for me. i also added in a media element to where it won’t be sticky anymore if the screen width is too small, like on a phone or something:

@ media (orientation: portrait), (max-width: 480px) {

.sidebar {
position: static;
}
}
