CSS is one of the most commonly used technologies in front-end development. It can not only beautify the page, but also achieve something cool. special effects.

First, we need to prepare an HTML structure containing two divs, one div represents the front of the card, and the other div represents the back of the card. An example is as follows:

2. CSS Styles

Next, we need to set CSS styles for the front and back of the card, as well as some basic styles for the entire card container. An example is as follows:

.card-container { perspective: 1000px; /* 设置透视视角 */ } .card { position: relative; width: 200px; height: 300px; transform-style: preserve-3d; /* 设置元素在3D空间中保持原有形状 */ transition: transform 0.5s; /* 设置过渡效果的时间 */ } .card-front, .card-back { position: absolute; width: 100%; height: 100%; backface-visibility: hidden; /* 隐藏背面元素 */ } .card-front { transform: rotateY(0deg); /* 设置初始正面朝向 */ } .card-back { transform: rotateY(180deg); /* 设置初始背面朝向 */ }

3. Flip animation effect

Finally, we need to set events for the card that trigger the flip animation, such as mouse hover or click events. We can use the :hover pseudo-class to trigger the flip effect on mouse hover, and use JavaScript to trigger the flip effect on click events. An example is as follows:

.card:hover { transform: rotateY(180deg); /* 鼠标悬停时翻转到背面 */ } .card.active { transform: rotateY(180deg); /* 点击时翻转到背面 */ }

var card = document.querySelector('.card'); card.addEventListener('click', function() { card.classList.toggle('active'); /* 切换active类名来触发翻转效果 */ });

With the above code, we can achieve a simple card flip effect. When the mouse is hovering over a card, the card will flip to the back immediately; when the card is clicked, the card will slowly flip to the back. The specific effects will be adjusted according to actual needs.
