How to Hide Pseudo Elements on Hover with CSS and jQuery

In web development, creating interactive elements such as tooltips is a common task. However, a problem often arises when these tooltips remain visible even when the user hovers over them. This can lead to confusion and hinder user experience. If you've ever wondered how to hide a tooltip or pseudo element when the cursor hovers over it, you're in the right place! In this guide, we'll explore a simple yet effective solution using CSS and jQuery.

Understanding the Challenge

The challenge here involves ensuring that a tooltip, which is created using a pseudo-element, disappears when the user moves their cursor over the tooltip itself. For example, consider a scenario where you want to provide helpful information for Scheme function names within a tooltip. When the user hovers over this tooltip for more information, it should ideally vanish, allowing for a smoother navigation experience.

Solution Overview

There are two primary methods to address the problem: through CSS and jQuery. The CSS method will utilize a special property called pointer-events, while the jQuery approach involves calculating the mouse's position. Let's dive into each solution.

Method 1: Using CSS with pointer-events

One of the simplest ways to hide a pseudo-element tooltip when hovered is by leveraging the pointer-events property in CSS. This property allows you to control how mouse events are sent to the elements.

Implementation Steps

Define Your Tooltip: Start by defining your tooltip as a pseudo-element using ::before.

Set pointer-events: Apply pointer-events: none; on the pseudo-element to prevent it from receiving any mouse events when hovered.

Here's how you can implement it:

Method 2: Using jQuery

If you prefer to handle the behavior dynamically or need more control, you can achieve this with jQuery by calculating the position of the cursor. However, this method can be more complex and may involve additional setup.

Considerations for jQuery Method

Mouse Event Tracking: You would need to add mouse event listeners to track when the cursor enters or leaves the tooltip.

Dynamic Adjustments: Adjust the visibility of the tooltip based on the cursor's position.

This method can get complicated and requires precise calculations around the tooltip’s position.

Conclusion

To enhance user experience when using tooltips in your web applications, the CSS method using pointer-events is efficient and straightforward. By ensuring your tooltip does not block mouse events when hovered, users can easily move their mouse without the tooltip remaining in the way.

Remember, while jQuery can provide additional flexibility, often a well-structured CSS solution is sufficient for tooltips and pseudo-elements. Happy coding!
