How to implement CSS using @import rule? 067

 How to implement CSS using @import rule?

Here's how to implement CSS using the @import rule:

1. Syntax:


@import url("stylesheet.css");

  • Replace stylesheet.css with the actual path to your external stylesheet.

  • You can import multiple stylesheets using multiple @import rules.

2. Placement:

  • Use @import within a stylesheet, either:

  • At the top of an external stylesheet, before any other style rules.

  • Inside a <style> element within the <head> of an HTML document.

3. Media Queries:

  • Import stylesheets conditionally based on device type or screen size:


@import url("print.css") print;
@import url("mobile.css") screen and (max-width: 480px);


  1. External Stylesheet:
    /* main.css */
    @import url("reset.css");
    @import url("typography.css");
    @import url("layout.css");

    /* Additional styles here */

  2. Internal Stylesheet:
        @import url("navigation.css");
        @import url("forms.css") screen and (min-width: 768px);

        /* Additional styles here */


  • Performance: Using @import can introduce a slight delay in loading styles, as browsers must make additional requests to fetch imported stylesheets.

  • Specificity: Imported styles have the same specificity as if they were written directly in the main stylesheet.

  • Maintenance: Overusing @import can make code harder to maintain as styles become spread across multiple files.

Best Practices:

  • Use external stylesheets: Prioritize linking external stylesheets directly using the <link> element in HTML for better performance and maintainability.

  • Use @import strategically: Reserve @import for specific cases like conditional loading or modularizing styles within a stylesheet.

  • Limit the number of imports: Avoid excessive imports to minimize performance impact and potential conflicts.

  • Consider alternatives: Explore CSS preprocessors like Sass or Less for advanced features like variables, mixins, and nesting, which can help organize and manage styles more effectively.
