How to Allow Mouse Interaction on Underlying Elements When Using Overlay Images?

Ignoring Mouse Interaction on Overlay Images

When incorporating an overlay image into a web user interface, it's essential to preserve the functionality of underlying elements. This article explores a solution that allows you to place a transparent overlay image over an object without hindering its mouse interaction.

Disable Mouse Interaction

To disable mouse interaction on the overlay image, we can utilize the CSS property pointer-events. By setting this property to none, we effectively make the overlay element invisible to mouse events while maintaining its visual presence.

CSS Stylization

The following CSS code exemplifies how to implement this solution:

<code class="css">#reflection_overlay {
    background-image: url(../img/reflection.png);
    background-repeat: no-repeat;
    width: 195px;
    pointer-events: none;
}</code>

This code applies the pointer-events property with a value of none to the element with the ID #reflection_overlay. As a result, any mouse clicks or hovers on the overlay image will no longer affect the underlying menu or any other elements beneath it.

Simple and Effective

Using the pointer-events attribute offers several benefits. It is:

• Cross-browser compatible: Works in most modern browsers.
• Simple to implement: Requires minimal CSS modifications.
• Lightweight: Introduces minimal overhead to your web page.

By implementing this solution, you can seamlessly overlay images without compromising the functionality of the underlying elements.
