How to Create a Sticky Element with Scrolled Inner Content

Have you ever wanted to create a sticky element on your website that remains fixed in place while the inner content continues to scroll? This is a great way to keep important information or controls always visible, even as the user scrolls down the page. In this article, we will show you how to create a sticky element with scrolled inner content using HTML and CSS.

What is a Sticky Element?

A sticky element is an element on a web page that remains fixed in place while the rest of the page scrolls. This can be useful for keeping important information or controls always visible, even as the user scrolls down the page. In contrast to a fixed element, a sticky element only becomes fixed when the user scrolls past it, and it returns to its original position when the user scrolls back up.

Creating a Sticky Element

To create a sticky element, you will need to use the position: sticky property in your CSS. This property is a combination of the position: relative and position: fixed properties, and it allows an element to behave as if it were fixed in place, but only when the user scrolls past it. Here is an example of how to create a sticky element:

div.sticky {
  position: -webkit-sticky; /* for Safari */
  position: sticky;
  top: 0;
  background-color: #f1f1f1;
  padding: 10px;
  font-size: 16px;
}

In this example, the div element with the class of sticky will remain fixed in place at the top of the page, as long as the user does not scroll past it. The top property specifies how far from the top of the page the sticky element should be positioned. In this case, it is set to 0, which means the sticky element will be positioned at the very top of the page.

Creating Scrolled Inner Content

To create scrolled inner content for a sticky element, you will need to use the overflow: auto property in your CSS. This property allows an element to display scrollbars when its content overflows. Here is an example of how to create scrolled inner content:

div.inner {
  overflow: auto;
  height: 200px;
  padding: 10px;
}

In this example, the div element with the class of inner will display scrollbars when its content overflows, and it will have a height of 200 pixels. The padding property is used to add some space around the content, so that the scrollbars do not overlap with it.

Combining Sticky Elements and Scrolled Inner Content

To combine sticky elements and scrolled inner content, you will need to nest the inner content inside the sticky element. Here is an example of how to do this:

<div class="sticky">
  <div class="inner">
    <p>This is the inner content.</p>
    <p>This is some more inner content.</p>
  </div>
</div>

In this example, the inner content is nested inside the sticky element. The sticky element will remain fixed in place at the top of the page, while the inner content will scroll inside it. Here is the CSS for this example:

div.sticky {
  position: -webkit-sticky; /* for Safari */
  position: sticky;
  top: 0;
  background-color: #f1f1f1;
  padding: 10px;
  font-size: 16px;
}

div.inner {
  overflow: auto;
  height: 200px;
  padding: 10px;
}

In this article, we have shown you how to create a sticky element with scrolled inner content using HTML and CSS. Sticky elements are a great way to keep important information or controls always visible, even as the user scrolls down the page. By using the position: sticky and overflow: auto properties, you can create a sticky element that remains fixed in place, while its inner content scrolls inside it. We hope this article has been helpful to you, and we encourage you to try creating your own sticky elements with scrolled inner content.
