Introduction

If you're working on creating an enticing user interface with jQuery, you might have encountered a common issue: combining multiple animations, like fadeIn() and animate(), to run simultaneously. By default, jQuery executes these animations sequentially, meaning one starts only after the other finishes. This can be frustrating when you're aiming for an engaging visual effect, such as the opening of Bootstrap modal windows. In this guide, we'll explore a straightforward solution to allow these animations to run in parallel, providing a more dynamic user experience.

The Problem

Imagine trying to mimic the smooth appearance of a modal window, where you want the element to fade in while it simultaneously moves to a specified position on the screen. The typical jQuery approach would stack these animations, resulting in a sandwich effect where the div fades in first, followed by the translation movement — not the simultaneous action you're looking for.

Here's an example of the problematic code:

While this code works, it doesn't achieve the desired simultaneous effect. So, how can we resolve this issue?

The Solution

The good news is that there's a straightforward way to run these animations concurrently. By wrapping the animated element in two separate <div> elements, we can manipulate the animations more effectively. Let's break down this solution step by step.

Step 1: Structure Your HTML

First, set up your HTML structure. You will need a parent <div> to handle the fading effect and a child <div> for the element you want to animate. For example:

Step 2: Apply CSS Styles

Now, add some necessary CSS styles to ensure that the child <div> is positioned correctly and hidden initially. You can use the following CSS as a guide:

Step 3: Revise Your jQuery Code

Now, modify your jQuery code to achieve the desired simultaneous effect. Here's how you can do that:

Explanation of the Code

FadeIn on Parent: The fadeIn(500) method applied to the parent <div> makes it visible over 500 milliseconds.

Animation on Child: The animate({top: 40}, 500) method is now called from within the fadeIn completion callback, ensuring that the animation starts as soon as the fade-in effect begins.

Delay: The delay(1000) method keeps the action from starting until a second has passed, providing a little breathing room.

Conclusion

By following these simple steps, you can create an engaging, visually appealing experience that allows fadeIn() and animate() to work in parallel. Wrapping the element in separate <div> tags clears the way for simultaneous animations, giving your modal windows the polished look you desire. Now, your users will be treated to a smooth transition that enhances their interaction with your site.
