I am sure this is simple, but I just cannot find it.
In the default installation on Yii and the default example website, the fields are marked with this green background color when all is success.
I have found the color to be:
And found it in main.css and form.css
I have removed it from both .css files. Deleted all assets files and restarted the server, but still the fields are marked green. How do I remove the green color?
