how can i remove time background

[Hunter]

I decided to do some inspect element and it looks like this is what affects the spacing:

.chapterThumbText {
padding: .05em 0;
}

Changed the padding from .25em to .05em, now the black bar highlight thing is smaller as the height is reduced.

/*Removes the black highlight over the trickplay image where the time is displayed*/

.chapterThumbTextContainer {
background: rgba(0,0,0,0);
}

This removes the black bar highlight part entirely.

Note I'm new to css code so its possible doing these changes has unexpected impacts on some other function somewhere in the code that uses the same container or something.
