Why LiveReload? If values are transferred from SASS to CSS, and to automate the display level changes to the HTML document, you can use BrowserSync.
in General, BrowserSync sinhroniziruete multiple browsers, so you can open chrome, Mozilla, browser on the phone and all the actions that you make in one of them (scroll, fill in forms, etc.) will automatically be available in other browsers
