Does Jquery Hover Fire Before Css

As a web developer, one of the most fascinating aspects of front-end development is the interplay between JavaScript and CSS. In this article, we’ll explore the question: Does jQuery hover fire before CSS? This topic is particularly interesting to me because it involves understanding the order in which different web technologies are executed, and how they interact with each other.

Understanding Event Handling in JavaScript and CSS

Before delving into the question at hand, let’s first understand how event handling works in JavaScript and cascading style sheets (CSS). In JavaScript, event handling allows us to respond to user interactions such as clicks, hovers, and key presses. On the other hand, CSS is responsible for styling the visual presentation of web elements, including hover effects.

The Order of Execution

When it comes to hover effects in web development, the order of execution between JavaScript and CSS becomes crucial. In the context of jQuery, the hover event is a popular choice for creating interactive web experiences. However, the question arises: does the jQuery hover event fire before the CSS hover effect, or vice versa?

From my experience and understanding, the order of execution is that the CSS hover effect takes precedence over the jQuery hover event. This means that when a user hovers over an element, the CSS hover effect will be applied before any JavaScript/jQuery code is executed.

Applying Personal Touches

During my own projects, I’ve encountered scenarios where I wanted to create custom hover interactions using jQuery. Understanding that the CSS hover effect takes priority has been crucial in crafting the desired user experience. By embracing this knowledge, I’ve been able to fine-tune the interplay between CSS and jQuery to create seamless and visually appealing hover effects.

Going Deeper into Detail

It’s important to note that while the CSS hover effect takes precedence, there are ways to leverage JavaScript and jQuery to enhance or modify the hover behavior further. For example, jQuery offers a range of methods and event handling capabilities that can complement the CSS hover effect, allowing for additional customization and interactivity.


After diving deep into the question of whether jQuery hover fires before CSS, it’s clear that understanding the order of execution between JavaScript and CSS is essential for creating engaging web experiences. While CSS hover effects take priority, the power of JavaScript and jQuery can still be harnessed to further enhance and customize user interactions. By leveraging this understanding, we can continue to push the boundaries of what’s possible in front-end web development.
