Creating a Javascript function to turn lights off using CSS manipulation, similar to the feature found

Is there a way to use JavaScript to obscure all elements on a page except for one specific HTML element?

This web application is optimized for Chrome, so CSS3 can also be utilized.

Answer №1

To create an overlay effect, utilize a single <div> element styled with position: fixed; covering the entire page. Apply a semi-transparent background color using

background-color: rgba(0, 0, 0, .5);
. Finally, position the desired content on top of this div.

Answer №2

A simple way to achieve the desired effect is by looping through each element in a webpage and changing their background color to black, excluding one specific element identified by its ID.

This task can be accomplished without relying on CSS3 features.
