How does it work?
To detect changes to the CSS, the extension relies on a WebSockets daemon running on the same webserver the page originated from. The daemon pushes down notifications whenever it detects changes to the CSS.
Even without a notifier running, the extension behaves normally, albeit without the live component. You may press F9 to request a refresh of the current page CSS.
Simple usage requires nothing more than the installation of the extension. Press F9 whenever you wish to reload the page CSS.
Live CSS updates require installation of a notification daemon on your development server (or localhost if that is the case). See the available notifiers on github.
Once you have the notifer installed and running, visit the webpage under development. Press F9. The extension will refresh the CSS and establish a connection to the notifier daemon. From here on, any change to a CSS file will automatically trigger a refresh of the page's CSS in the browser.
