Methods and techniques on how to achieve image carousel effects through pure CSS

2. CSS Style

Next, we need to set the CSS style for the image carousel. Here are the basic CSS styles needed to achieve the image carousel effect:

.carousel { width: 500px; /* 设置轮播容器的宽度 */ height: 300px; /* 设置轮播容器的高度 */ overflow: hidden; /* 隐藏超出容器范围的内容 */ position: relative; /* 设置轮播容器为相对定位，以便定位轮播元素 */ } .carousel img { width: 100%; /* 设置轮播图片为容器的百分百宽度 */ height: auto; /* 高度自适应，保持原始图片比例 */ position: absolute; /* 设置轮播图片为绝对定位，以便实现叠加效果 */ }

In this example, we added a fixed width and height to the carousel container.carousel, andoverflow: hiddenAttribute allows content beyond the scope of the container to be hidden. We also set the width of the carousel image.carousel imgto 100% so that the width of the image adapts to the container, and set the image to absolute positioning to achieve the overlay effect.

3. CSS Animation

Now we need to use CSS animation to achieve the switching effect of the image carousel. The following is an example of a CSS animation declared using@keyframes:

@keyframes carousel-animation { 0% { left: 0; } /* 初始状态，图片位于容器最左边 */ 25% { left: -500px; } /* 图片向左移动一个容器宽度的距离 */ 50% { left: -1000px; } /* 图片继续向左移动一个容器宽度的距离 */ 75% { left: -1500px; } /* 图片继续向左移动一个容器宽度的距离 */ 100% { left: 0; } /* 图片回到初始位置 */ } .carousel img { animation: carousel-animation 10s infinite; /* 应用动画，持续10秒，无限循环 */ }

In this example, we use the@keyframeskeyword to declare an animation namedcarousel-animationanimation, and defines the status of the animation at different points in time. We gradually change the value of theleftattribute to allow the image to move horizontally within the container to achieve a carousel effect. Finally, we applied this animation in.carousel imgand set the duration of the animation to 10 seconds and the number of loops to infinite.

4. Summary

Through the above HTML structure and CSS style, as well as the image carousel effect achieved using CSS animation, we can easily display the switching effect of multiple images on the web page. . By adjusting the size of the container, the position of the image and the parameters of the animation, we can achieve a customized image carousel effect.
