Style the navigation control arrows and progress bar

Navigation control arrows

To change the color of the navigation controls, insert:

.reveal .controls {
    color: #42affa;
}

Progress bar color

You can define two colors for the progress bar: the background color and the color of the progress bar itself:

.reveal .progress {

	/*The color of the background*/
    background: rgba(0, 0, 0, 0.2);

	/*The color of the progress bar*/
    color: #42affa;
}
