Troubleshooting CSS Transitions with Inline Variables

When working with CSS transitions, you may encounter a frustrating problem where your inline variables aren't being picked up appropriately. This often leads to inconsistent and unexpected behavior in your animations, particularly when you are trying to sequence transitions based on these variables. In this guide, we'll dissect the issue and provide you with a clear step-by-step solution to ensure your transitions work smoothly and effectively.

Understanding the Problem

The issue usually arises when the inline CSS variables are not in sync with your transition effects. For example, you may have a section of your HTML that looks like this:

[[See Video to Reveal this Text or Code Snippet]]

In the CSS, you might try to use the variable like this:

[[See Video to Reveal this Text or Code Snippet]]

However, if the .hidden class is set to override these styles, your transitions won't trigger as intended. Essentially, the hidden class is preventing the desired transitions from occurring smoothly.

Solution Overview

To address this issue, we need to make some adjustments in our code. We’ll ensure the transition effects are applied properly when toggling between the hidden and show classes. Below are the steps and code snippets needed to implement this solution effectively.

Step 1: Modify the CSS

Instead of using transition-delay, we will apply the transition directly to the properties that we want to animate with timing and order taken into account:

Step 2: Adjust JavaScript Class Toggles

In your JavaScript, ensure that the hidden class is toggled correctly whenever an element enters or exits the viewport. Modify your Intersection Observer as follows:

Conclusion

By making the above modifications, you can effectively address the issue of CSS transitions not picking up your inline variables. This ensures a smoother animation experience as elements transition into view based on their specified order. Remember that careful management of class states and CSS properties is key to achieving effective transitions.
