Launching "ng serve" and "ng serve -ec -sm" changes the order the styles are loaded from styles.scss
Look at:
- src/styles.scss
- packages.json: notice the 'start' and 'start:debug' scripts
Then, "npm install" and launch both 'npm run start' and 'npm run start:debug'. Then visit localhost:4200 and localhost:3000 to see a difference. Notice the css is not applicated seamlessly between the two instances of the app.
