CSS compression property guide: minify and compress, specific code examples required

In front-end development, optimizing web page performance is a key task. Effectively optimizing CSS code can greatly improve the loading speed and user experience of your web pages. And compressing CSS is a common optimization technique that can reduce file size and increase page load speed. In this article, we will learn how to use minify and compress, two commonly used CSS compression properties, and provide specific code examples.

1. minify property
   The minify property of CSS is used to streamline CSS code, remove unnecessary spaces, newlines, and comments, and compress the code into one line. This compression method can effectively reduce file size, but it can make the code difficult to read and maintain. The following is an example code for compressing CSS using the minify attribute:

/* 原始 CSS 代码 */
body {
    background-color: #f1f1f1;
    color: #333;
    font-size: 16px;
}

h1 {
    color: #ff0000;
    font-size: 24px;
}

/* 压缩后的 CSS 代码 */
body{background-color:#f1f1f1;color:#333;font-size:16px;}h1{color:#ff0000;font-size:24px;}

In the above code example, the original CSS code contains multiple spaces and newlines, and the compressed code is compressed into One line, with unnecessary spaces and newlines removed. As you can see, the compressed code is more compact and the file size is reduced a lot.

2. compress attribute
   The compress attribute of CSS is similar to the minify attribute and is also used to compress code. The difference is that the compress attribute will further compress and optimize the code, removing useless CSS rules and declarations. The following is a sample code that uses the compress attribute to compress CSS:

/* 原始 CSS 代码 */
body {
    background-color: #f1f1f1;
    color: #333;
    font-size: 16px;
}

h1 {
    color: #ff0000;
    font-size: 24px;
}

p {
    color: #000;
    font-size: 14px;
    line-height: 1.5;
}

/* 压缩后的 CSS 代码 */
body{background:#f1f1f1;color:#333}h1{color:#f00}p{color:#000;line-height:1.5}

In the above code sample, the original CSS code contains multiple CSS rules and declarations, and the compressed code removes useless CSS rules and declarations, and simplified color values, etc. The compressed code is more streamlined, reducing file size and load time.

Summary:
Compressing CSS is an effective method when optimizing web page performance. By using the minify and compress CSS compression properties, you can compress and streamline your CSS code, reducing file size and increasing page load speed. However, it should be noted that using compression attributes may affect the readability and maintainability of the code, so code compression and maintenance costs need to be weighed in actual development. I hope this article helps you understand and apply CSS compression properties!
