Use react-transition-group in React to achieve seamless switching animations
In React development, react-transition-group is a common library for implementing animation switching between components. However, in practical applications, developers often encounter situations where the animation effect is not ideal, such as blank areas appearing when component switching, resulting in the animation not being smooth enough. This article analyzes this problem and provides solutions.
Problem Description: The goal is to realize a component switching animation that slides from right to left, requiring the two components to be closely connected during the animation process without any gaps. But the actual effect is that there is blank space between components.
Question code example:
<switchtransition>
<csstransition classnames="checkout" key="{this.state.isPhone}" timeout="{500}">
{this.state.isPhone ? (
<phone handleback="{()"> this.setPhoneState(false)} handlePhoneClick={this.handlePhoneClick} />
) : (
<main handlephoneclick="{this.handlePhoneClick}"></main>
)}
</phone></csstransition>
</switchtransition>
Corresponding CSS style:
.checkout-enter {
transform: translateX(100%);
}
.checkout-enter-active {
transform: translateX(0);
transition: all 500ms;
}
.checkout-exit {
transform: translateX(0);
}
.checkout-exit-active {
transform: translateX(-100%);
transition: all 500ms;
}
Problem analysis: The above CSS code defines the in-and-out effect of the animation, but does not consider the positional relationship of components during the animation process, resulting in gaps between components.
Solution: The key is to use position: absolute property and precisely control the component's position during the animation process.
Corrected CSS style:
.checkout-enter {
position: absolute;
right: 0;
transform: translateX(100%);
}
.checkout-enter-active {
transform: translateX(0);
transition: all 500ms;
}
.checkout-exit {
position: absolute;
left: 0;
transform: translateX(0);
}
.checkout-exit-active {
transform: translateX(-100%);
transition: all 500ms;
}
By setting position: absolute , and positioning the incoming and exiting components to the right and left of the container respectively, ensure that the components are always closely connected during the animation process, thereby eliminating blank areas and seamlessly switching animation effects. This makes the animation smoother and the user experience better.

What are common CSS browser inconsistencies?
Jul 26, 2025 am 07:04 AM
Different browsers have differences in CSS parsing, resulting in inconsistent display effects, mainly including the default style difference, box model calculation method, Flexbox and Grid layout support level, and inconsistent behavior of certain CSS attributes. 1. The default style processing is inconsistent. The solution is to use CSSReset or Normalize.css to unify the initial style; 2. The box model calculation method of the old version of IE is different. It is recommended to use box-sizing:border-box in a unified manner; 3. Flexbox and Grid perform differently in edge cases or in old versions. More tests and use Autoprefixer; 4. Some CSS attribute behaviors are inconsistent. CanIuse must be consulted and downgraded.
