Position

The position CSS property sets how an element is positioned in a document. The top, right, bottom, and left properties determine the final location of positioned elements.

For responsive

add -sm, -md, -lg or -xl to class name, for example:

<div class="position-md"></div>

.sticky {
    position: sticky;
}
.relative {
    position: relative;
}
.absolute {
    position: absolute;
}
.fixed {
    position: fixed;
}
.static {
    position: static;
}
