What?
No, Frog!
You comment out the css with tags: /* this opens and this> closes*/
It would look like this:
/*.view:hover, iconview:hover, .view:hover:focus, iconview:hover:focus, .view text:hover, iconview text:hover, textview text:hover, iconview text:hover:focus, textview text:hover:focus, flowbox flowboxchild:hover, row:hover, .view:selected, iconview:selected, .view:selected:focus, iconview:selected:focus, .view text:selected, iconview text:selected, textview text:selected, iconview text:selected:focus, textview text:selected:focus, .view text selection:focus, iconview text selection:focus, .view text selection, iconview text selection, textview text selection:focus, textview text selection, flowbox flowboxchild:selected, entry selection, entry selection:focus, row:selected {
background-color: rgba(0, 170, 255, 0.5);
}*/
If launching from terminal...

Then navigate to the "other software" tab.
