[jeremycherfas] Exactly! But if you look at the source, you can see, for example `<g ct:series-name="Hours logged 2018" class="ct-series ct-series-a"><line x1="65.17847188313802" x2="65.17847188313802" y1="408.9666748046875" y2="408.9666748046875" class="ct-bar" ct:value="0"></line>` which contains the `class` that is in `custom.css`
