I am having the hardest time trying to figure out how to style that line.

I know that the class is called `is-drop-target` but I can't scroll through the list of styles to figure out what styles are applied to which properties because the cursor is holding the tab for the class to show and scrolling is not allowed when the cursor is holding something.

I've tried properties `background-color`, `border-color` and `color` but none of them worked.

I've tried pseudo-elements `::before` and `::after` but neither of those worked either.

Any suggestions would be greatly appreciated. Thanks!

**EDIT:**   

I am using `UI Theme` named `seti-ui`. <https://atom.io/themes/seti-ui>
