Insert line between gutter and main editor


I like the “One Light” theme, but am annoyed that the main editor and gutter bar just bleed into each other. Is there a way to draw a line between them?


I have the following in my styles.less:

atom-text-editor .gutter-container div::after {
  content: "";
  width: 5px;
  margin-right: 3px;
  background: -webkit-linear-gradient(left, #111 0%,#282c34 100%);
