Stylelint
WebStorm integrates with Stylelint so you can inspect your CSS code from inside the IDE. Stylelint wakes up automatically when you edit a CSS file and highlights the detected problems. To view the description of a problem in a pop-up information window, hover the mouse pointer over a stripe in the Validation sidebar. To examine errors and apply suggested quick fixes, press Alt+Enter.
Installing Stylelint
Open the embedded Terminal ( or Alt+F12) and type
npm install -g stylelint
at the command prompt.
Activating and configuring Stylelint
In the Settings/Preferences dialog (Ctrl+Alt+S), click Stylesheets under Languages and Frameworks, and then click Stylelint. The Stylelint page opens.
