Why Do CSS and React Behave Differently?

If you've recently started working with React, you may have encountered situations where your CSS behaves differently in a React component than in a simple HTML setup. This discrepancy can be especially frustrating when creating components like flip cards that are expected to perform a specific visual action, such as flipping without altering size. In this guide, we'll delve into a specific issue faced by a developer when transforming a flip card from standard HTML to a React component.

The Problem at Hand

The developer faced an issue where the back side of a flip card was increasing in size when flipping. While the same code worked fine in plain HTML, the React version did not yield the expected behavior. Here’s a summary of the problem:

Issue: The back side of the flip card increased in size on flip when managed by React.

Expected Behavior: The card should retain the same dimensions when flipped, similar to its behavior in plain HTML.

The Flip Card Code Breakdown

Let’s look closely at the code that was causing the problem. Below is the structure of the cards with their respective CSS.

Analyzing the Issues

Upon examining the code, it became clear why the React version appeared to function differently:

CSS Conflicts: If there are other CSS files or components affecting styles, such conflicts can produce unexpected results.

Component State or Lifecycle: React manages state and lifecycle differently, which can affect how styles are applied or updated.

Important Note: Avoiding CSS Conflicts

In the original report by the developer, it was noted that the index.css file was empty and there were no other CSS components conflicting with the Flip component. This helped narrow down the issues significantly.

Solution: Eliminating the Problem

The issue was eventually resolved when the developer simplified their project by removing unnecessary components. This led to correct behavior in the flip card component.

Steps to Fix CSS Issues in React:

Isolate the Component: Make sure your component is self-contained and doesn't inherit styles from other components or global stylesheets inadvertently.

Remove Conflicting Components: If removing other components helps, then carefully reintroduce them one by one to identify the source of conflict.

Debug Gradually: Start with simple styling to ensure it works as expected before moving on to more complex CSS or animations.

Conclusion

Working with CSS in React does require some adjustment, especially when integrating animations or complex styles. By isolating components and methodically debugging issues, you can resolve most problems effectively.
