top: 1px; // because of our border trick (see below), we're off by 1px of aligntment
display: flex;

overflow: hidden; // this is cheaper than a `max-height: calc(100% - 4px)` in the bar's CSS.
// A bar is meant to be a 2x2 circle when at zero height, and otherwise a 2px wide line
// with rounded caps.

border: 1px solid transparent; // transparent means we'll use the background colour
border-radius: 2px; // rounded end caps, based on the border
min-height: 0; // like the width, we'll rely on the border to give us height
max-height: 100%; // this makes the `height: 42%` work on the element
margin-left: 1px; // we want 2px between each bar, so 1px on either side for balance
margin-right: 1px;
// background color is handled by the parent components
