How Can I Create Clickable Text Under an Overlay Without Blocking Mouse Events?

Overcoming Click Interference with an "Invisible" Div

To enhance the usability of web pages, it's often desirable to overlay elements atop text, but without hindering click functionality on the underlying content. This quandary arises when the overlay div obstructs mouse events from reaching clickable elements beneath it.

Fear not, CSS offers a solution through the pointer-events property. Supported by modern browsers such as Firefox 3.6 , Chrome 2 , IE 11 , and Safari 4 , this property allows you to configure the behavior of mouse events on specific elements.

To make an overlay div "invisible" to clicks, simply apply the following CSS rule:

<code class="css">#overlay {
  pointer-events: none;
}</code>

This code effectively tells the browser to ignore mouse events initiated from within the #overlay div. As a result, the underlying text remains accessible for clicking, selection, and other mouse interactions.

Here's a revised code snippet demonstrating this technique:

<code class="html"><div id="container">
    <p>Some text</p>
    <div id="overlay" style="position: absolute; top: 0; left: 0; width: 100%; height:100%">
        ... some content ...
    </div>
 </div></code>

<code class="css">#overlay {
  pointer-events: none;
}</code>

By leveraging pointer-events, you can create overlay divs that seamlessly enhance web pages without disrupting the user's intended interactions.
