How To Name Css File

When it comes to web development, properly naming and organizing your files is crucial. This is particularly true for CSS files, as a well-structured and organized collection of stylesheets can significantly improve the maintainability and efficiency of your project. In this blog post, we will discuss some best practices for naming your CSS files, ensuring that your styles are easy to locate and understand for both you and others working on the project.

1. Use Descriptive Names

First and foremost, make sure to give your CSS files descriptive names that accurately represent their contents. This will make it much easier to locate the correct file when you need to make edits or additions. For example, if you have a file containing styles for your site’s navigation menu, you might name it navigation.css or menu.css rather than something generic like styles.css or main.css.

2. Use Lowercase and Hyphens

To ensure consistency across platforms and avoid potential conflicts, it’s a good idea to use lowercase letters for your file names. Additionally, separate words in your file names with hyphens (-) instead of underscores (_) or spaces. For example, instead of naming your file HeaderStyles.css or header_styles.css, use header-styles.css.

3. Group Related Files in Folders

When you have multiple CSS files, it’s a good idea to group related files together in folders. This can help you keep your project organized and easy to navigate. For example, if you have separate CSS files for various components of your site like the header, footer, and sidebar, you might place them in a folder called components. Similarly, if you have different stylesheets for various pages, you can place them in a folder called pages.

4. Use a “main” or “base” File

In addition to organizing your individual CSS files, consider creating a “main” or “base” CSS file that contains the core styles used throughout your site. This can include things like font types, background colors, and general layout styles. Name this file something like main.css or base.css, and then use the @import rule to include your individual component and page-specific stylesheets.

For example, your main.css file might look something like this:

    /* Import component styles */
    @import url("components/header-styles.css");
    @import url("components/footer-styles.css");

    /* Import page-specific styles */
    @import url("pages/homepage-styles.css");
    @import url("pages/about-us-styles.css");

    /* General styles */
    body {
        font-family: Arial, sans-serif;
        background-color: #f0f0f0;

5. Version Your Files (Optional)

In some cases, it can also be helpful to version your CSS files. This can be particularly useful if you are working on a large project with multiple developers or if you are making significant changes to your site’s design. To version your files, simply include a version number in the file name, such as header-styles-v1.0.css. Remember to update this number whenever you make significant changes to the file.


Properly naming and organizing your CSS files can greatly improve the maintainability of your projects, making it easier for both you and others to locate and update styles as needed. By following these best practices for naming your CSS files and using descriptive names, lowercase letters and hyphens, grouping related files, and implementing a main or base file, you’ll be well on your way to creating a more efficient and organized project.
