Remove Black Background When Hovering

Question

I'm on my early stages of creating a Rails application. What I wanted to do is remove the black background on the links when hovering the cursor on them (as shown in the image). How? I did not add anything on the css files. I'm using Rails 3.2

Answer 1

Seems to be that the culprit to this is at assets/stylesheets/scaffolds.css.scss

a:hover {
  color: #fff;
  background-color: #000;
}
