CSS and Minification
CSS (Cascade Styling Sheets) are files that control the style of your website by connecting style properties to html elements.
In Shopify, you’ll find CSS files in your theme Assets folder.
What is minification?
CSS are text files. Minification compresses the text by removing extra characters like spaces and comments, and combining common styles.
This makes the file size smaller. When your files are lighter they transfer faster, which helps your site load faster.
You want to compress your files, but you also want them to be readable so you can edit and make updates.
No worries, Shopify has a technique that compresses your human readable CSS files into minified files on the server.
