In React apps, smooth page transition animation is crucial. This article will solve a common problem: use react-transition-group
to achieve tightly fit page switching to avoid unnecessary blanks.
Many developers will encounter blank areas when using react-transition-group
. Ideally, the page should slide smoothly from one side and out the other, with the two pages always closely connected. However, the actual effect often appears blank.
Let's analyze a typical code example:
<switchtransition> <csstransition classnames="checkout" key="{this.state.isPhone}" timeout="{500}"> {this.state.isPhone ? ( <phone handleback="{()"> this.setState({ isPhone: 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; }
While the code seems to set the entry and exit animation correctly, the occurrence of blank areas is usually due to layout or CSS style issues.
Solution:
Layout consistency: Ensure that the parent container of both components (
Phone
andMain
) has the same size and that the size remains the same during the animation process. This can avoid gaps caused by size differences during animation.Absolute positioning: Use absolute positioning (
position: absolute
) to accurately control component positioning to ensure that they are always close to each other during animation. The parent container needs to be set to relative position (position: relative
).CSS optimization: In CSS, using
position: absolute; top: 0; left: 0; right: 0; bottom: 0;
can ensure that the component completely fills its parent container to avoid blanks.
Improved CSS example:
.checkout-enter, .checkout-enter-active, .checkout-exit, .checkout-exit-active { position: absolute; top: 0; left: 0; right: 0; bottom: 0; } .checkout-enter { transform: translateX(100%); } .checkout-enter-active { transform: translateX(0); transition: transform 500ms; /* clearer transition attribute*/ } .checkout-exit { transform: translateX(0); } .checkout-exit-active { transform: translateX(-100%); transition: transform 500ms; /* clearer transition attribute*/ }
Through the above adjustments, blank areas during page switching can be effectively avoided, and a smooth and tight page transition effect can be achieved. Remember, the key is to make sure the components always occupy the same space and maintain precise control of position during animation.

To avoid taking over at high prices of currency speculation, it is necessary to establish a three-in-one defense system of market awareness, risk identification and defense strategy: 1. Identify signals such as social media surge at the end of the bull market, plunge after the surge in the new currency, and giant whale reduction. In the early stage of the bear market, use the position pyramid rules and dynamic stop loss; 2. Build a triple filter for information grading (strategy/tactics/noise), technical verification (moving moving averages and RSI, deep data), emotional isolation (three consecutive losses and stops, and pulling the network cable); 3. Create three-layer defense of rules (big whale tracking, policy-sensitive positions), tool layer (on-chain data monitoring, hedging tools), and system layer (barbell strategy, USDT reserves); 4. Beware of celebrity effects (such as LIBRA coins), policy changes, liquidity crisis and other scenarios, and pass contract verification and position verification and
