Some times you will need to use the rule !important
to override GuidedTrack's default styles:
*html
<style>
.my-fancy-header-class {
color: purple !important;
font-weight: bold !important;
font-size: 96px !important;
}
</style>
Thanks for pointing out that the example in the documentation had stopped working since the last update of GuidedTrack's styles. It has already been updated.
