Stilo CSS Editor

Stilo CSS Editor lets you add custom styles to your Shopify store from the theme editor. There is no separate app dashboard and no theme file editing. After installing, switch on Custom CSS under App embeds, paste your styles, and watch the preview update. Your CSS is served by Shopify with no external requests and no storefront JavaScript. Apply it to all pages or one page type, and switch it off without losing your code. Works with Online Store 2.0 themes.
