Instant CSS


Use the power of Visual Studio Code in WordPress to write your CSS or SCSS

The plugin uses autoprefixer to parse your CSS/SCSS into CSS that will work on older browsers, no need to write -webkit, -moz or -o.

You can also choose to use SCSS, more info about SCSS here:


  • Use all the powerful features from Visual Studio Code
  • Your CSS gets compiled with autoprefixer to work on older browsers
  • Use SCSS to create efficient stylesheets with variables, mixins, etc.
  • Option to minify your CSS to reduce loading times
  • No refreshing on saving
  • Live editor updating styles on save and have the browser update simultaneously

Honestly, this is the only sane way of writing CSS inside WordPress, making the experience as good as coding on your computer in a proper editor. I don't understand why this doesn't have thousands of downloads. It's been a massive game-changer at our agency, allowing people at all levels to start learning and using SASS. A couple of things that could improve on this: Support for multiple files, so we could use SASS partials. An improved live editor, which feels a little rudimentary. For example, offer an option to align the editor underneath the preview pane, and add buttons to resize the preview pane (similar to customizer) for testing responsive design. But anyway, soooo much gratitude. If you need more support to keep developing this, we'd be completely behind paying for a pro version, as long as there's developer option for unlimited sites, because Instant CSS is basically part of our WordPress Core here now 😊 Thanks again!

Hi! really great plugin, works fast, you can save with cmd+s like in vscode, reload without losing the row where you modified last and what is best, is that you can write scss in WordPress! thank you for this free option and hope you maintain the project! ps. would be great to see in the future, a Tidy css function. Some other plugins have this on a shortcut 'shift+tab'. Best regards!

Less/SCSS is that much cleaner and powerful than CSS alone. But it was always a hastle to implement it in websites where you only want some extra CSS. I wanted something that can be edited in the backend and can compile Less or SCSS. I almost gave up, but then this Plugin comes along! It deserves so much more attention! It works perfect, the Editor is fine, all the compiling is just seamless. It works out of the box the way it should! Of course, for big tasks or lot's of css, i would still prefer having it compiled locally (when working with Netbeans for example). But for these little fixes on existing customer pages, or nicely encapsulating your extra stuff using SCSS, this is just great! Huge thanks to the developer!
