HTML-CSS: Tips of the Day

How does the "position: sticky;" property work?

Sticky positioning is a hybrid of relative and fixed positioning. The element is treated as relative positioned until it crosses a specified threshold, at which point it is treated as fixed positioned.

You must specify a threshold with at least one of top, right, bottom, or left for sticky positioning to behave as expected. Otherwise, it will be indistinguishable from relative positioning.

So in your example, you have to define the position where it should stick in the end by using the top property.

HTML Code:

<nav>
  <ul align="left">
    <li><a href="#/contact" class="nav-selections" style="margin-right:35px;">Contact</a></li>
    <li><a href="#/about" class="nav-selections">About</a></li>
    <li><a href="#/products" class="nav-selections">Products</a></li>
    <li><a href="#" class="nav-selections">Home</a></li>
  </ul>
</nav>

CSS Code:

html, body {
  height: 200%;
}

nav {
  position: sticky;
  position: -webkit-sticky;
  top: 0; /* required */
}

.nav-selections {
  text-transform: uppercase;
  letter-spacing: 5px;
  font: 18px "lato", sans-serif;
  display: inline-block;
  text-decoration: none;
  color: white;
  padding: 18px;
  float: right;
  margin-left: 50px;
  transition: 1.5s;
}

.nav-selections:hover {
  transition: 1.5s;
  color: black;
}

ul {
  background-color: #B79b58;
  overflow: auto;
}

li {
  list-style-type: none;
}
