How Can I Detect Click Events Only on a Pseudo-Element, Not Its Parent?

Detecting Click Events on Pseudo-Elements

Question:

Despite attempts to implement a click event listener on a pseudo-element (a red overlay in this case), the event is also triggered on the main element (a blue background). The objective is to isolate click detection to solely the pseudo-element.

Answer:

Pseudo-elements, such as the red overlay in the provided JavaScript fiddle, are not part of the Document Object Model (DOM). Consequently, they cannot directly receive event bindings. In this situation, the click event is associated with the parent element (the blue background).

To activate a click event handler exclusively for the red region, it requires creating a child element, such as a span, within the main element and applying styles accordingly. This child element serves as the target for the click event rather than the pseudo-element.

By employing this strategy, the click event can be isolated to the desired area, catering to the specific need of responding to interactions with the pseudo-element without affecting the encompassing element.
