I've followed the first part of this guide by:
- Creating and applying my own theme.
- Using the
web/css/source/_extend.less that's on the guide.
- Deleting the mentioned directories.
- Refreshing the page.
But the button style did not change.
What am I missing?
Login to admin, go to System -> Cache Management in the bottom of the page you could see the three flush cache button option. click the JS/css and static flush cache button then clear the cache of your browser also. load the page it will get reflect.
have good luck
