How to remove border between widgets with Qt Style Sheets?

Question

Qt

Good afternoon. I am writing a text editor in Qt 5.5. When I started designing, I decided to use qss and ran into a problem. I want to make the background of the editor and the background of the status bar merge a la Sublime Text 3 and become one. Well, I set the background color to the same, and this is what happened:
border: none; tried.
