We can use the @import rule to implement how to introduce another CSS file into a CSS file. The @import rule can import multiple CSS files into the main HTML file or the main CSS file. This article will give you a detailed introduction. ,I hope to be helpful.
@import rules
First let’s understand the @import rules.
@import rules are used to import one style sheet into another style sheet. This rule also supports media queries so that users can import media-related style sheets. The @import rule must be declared at the top of the document after any @charset declaration. [Video tutorial recommendation: CSS tutorial]
Features of @import:
● @import rules are used to import style sheets into HTML pages or Other style sheets.
● @import rules are also used to add media queries, so import is media-dependent.
● @import rules are always declared at the top of the document.
Basic sentence pattern:
@import url | string list-of-mediaqueries;
url | string: Indicates the location of the resource to be imported, which can be relative or absolute.
list-of-mediaqueries: Determines the application of CSS rules defined in URL links.
Code Example
Let’s use examples to show you how to introduce another CSS file into a CSS file.
HTML part: Create a file named index.html
<!DOCTYPE html> <html> <meta charset="UTF-8"> <link rel="stylesheet" href="style1.css" /><!--在HTML文件中导入style1.css文件--> <head> <body> <div class="box"> <h1 id="PHP中文网">PHP中文网</h1> <p>测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！测试文本！</p> </div> </body> </html>
CSS part:
/*导入另一个CSS文件 */
@import "style2.css"; /* 或者@import url(style2.css);*/
.box{
width: 400px;
margin: 100px auto;
}
h1 {
color:red;
text-align: center;
}
p {
color:black;
padding: 10px;
background-image: linear-gradient(to right, #fbd6d3, #ff1200);
position:static;
} Output: Importing another CSS file (style2.css) without using the @import rule
body {
background:gainsboro;
opacity: 0.5;
}
h1{
color: #008000;
}Output: Use the @import rule in the style1.css file to import the style2.css file
Note: There are two ways to use the @import rule to import another CSS style sheet: @import url(style2.css); and @import "style2.css";
Note: When using the @import rule to import another CSS style sheet, you need to pay attention to the path of the style sheet.
