How Can I Keep a Div Scrolled to the Bottom Using CSS?

Using CSS to Keep Overflow Div Scrolled to Bottom

Many developers face the challenge of keeping a div scrolled to the bottom, especially when new content is dynamically added. This problem becomes even more complex when users are allowed to scroll up but should not automatically return to the bottom unless they manually scroll down again.

CSS Solution

A simple and effective solution to this issue lies within CSS, specifically the flex-direction property. By setting flex-direction: column-reverse, the browser interprets the bottom of the div as the top, creating a reversed behavior. This allows the div to stay scrolled to the bottom even when new content is added.

Browser Support

It's important to note that this solution relies on flexbox, which has wide browser support. Most modern browsers, including Chrome, Firefox, Edge, and Safari, support flexbox.

Example Code

<code class="css">.container {
  height: 100px;
  overflow: auto;
  display: flex;
  flex-direction: column-reverse;
}</code>

<code class="html"><div class="container">
  <div>Bottom</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Hi</div>
  <div>Top</div>
</div></code>

Reverse Markup

As the browser treats the bottom as the top, it's essential to arrange the markup in reverse order to display the content correctly.

This CSS-based solution provides a simple and elegant way to keep a div continuously scrolled to the bottom, even with dynamically added content, while also allowing users to scroll up without immediately jumping back down.
