How to achieve smooth scrolling background effect of web pages through pure CSS
Background is a very important part of web design, which can enhance the visual effect and user experience of the page. Traditional web page backgrounds are usually static, but by using pure CSS technology, we can achieve a smooth scrolling background effect, thereby adding a more dynamic and vivid visual effect to the web page. In this article, we will introduce how to use CSS to achieve a smooth scrolling background effect, and provide specific code examples.
1. Preparation
Before we start to achieve the smooth scrolling background effect, we need to prepare some basic HTML and CSS code. First, we need to create a basic HTML file and then introduce a CSS file into it so that we can write code in the CSS file to achieve the smooth scrolling background effect. Here is a basic HTML structure example:
<!DOCTYPE html> <html> <head> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <div class="background"></div> <div class="content"> <!-- 网页内容 --> </div> </body> </html>
In the above example, we have created a background layer (div.background
) and a content layer (div.content
), the background layer will be used to achieve a smooth scrolling background effect, and the content layer will be used to place other web content.
2. Achieve smooth scrolling background effect
Next, let us write CSS code to achieve smooth scrolling background effect. The following is a code example:
body { margin: 0; padding: 0; overflow: hidden; } .background { position: fixed; top: 0; left: 0; width: 100%; height: 100vh; /* 占满整个可视区域 */ background-image: url(background.jpg); /* 背景图片路径 */ background-size: cover; /* 背景图片适应屏幕尺寸 */ background-position: center; /* 背景图片居中显示 */ z-index: -1; /* 确保背景层在内容层下方 */ animation: scrollBackground 30s linear infinite; /* 启用滚动动画 */ } @keyframes scrollBackground { 0% { transform: translateY(-50%); } 100% { transform: translateY(50%); } }
In the above CSS code, we first set the overflow
attribute of the body
element of the web page to hidden
, to hide the scrollbar. We then fixed the background layer in the viewport using position: fixed
, width: 100%
and height: 100vh
to set the size of the background layer to and The background-image
and background-size
attributes are used to specify the path and scaling method of the background image, and the background-position
attribute is used to control the background image. s position. Finally, we use the animation
attribute to apply the scroll animation to the background layer, where scrollBackground
is the animation name we defined, 30s
represents the time to scroll once, linear
means the animation transition is linear, infinite
means the animation plays in an infinite loop. In the @keyframes
rules of animation, we use the translateY
function of the transform
attribute to achieve the scrolling effect in the vertical direction.
3. Try the effect
After completing the above code, we can open the HTML file in the browser to view the smooth scrolling background effect. As you scroll the page, the background layer will appear in a smooth scrolling manner, giving you the feeling of being there.
Summary
Through pure CSS technology, we can easily achieve the smooth scrolling background effect of web pages. With just a few lines of CSS code, you can add a dynamic and vivid visual effect to your web page.

Choosing Flexbox or Grid depends on the layout requirements: 1) Flexbox is suitable for one-dimensional layouts, such as navigation bar; 2) Grid is suitable for two-dimensional layouts, such as magazine layouts. The two can be used in the project to improve the layout effect.

The best way to include CSS files is to use tags to introduce external CSS files in the HTML part. 1. Use tags to introduce external CSS files, such as. 2. For small adjustments, inline CSS can be used, but should be used with caution. 3. Large projects can use CSS preprocessors such as Sass or Less to import other CSS files through @import. 4. For performance, CSS files should be merged and CDN should be used, and compressed using tools such as CSSNano.
