Forexample, the measurement widget. The existing style 'measurementDiv' taken from esri.css looks like this.
Lets say I dont like the icons and I want to change its css. Then how can I go about doing that ? I know these widgets take their style and icons from esri.css, but this file is not located in webapp builder dev edition folder. It is referenced from an Esri server in init.js. So what is the correct procedure to overwrite this file?
