Trying it out, there seems to be a gap between the headers when one starts pushing another:
| {path: 'style', component: StyleDemo}, | ||
| {path: 'typography', component: TypographyDemo}, | ||
| {path: 'expansion', component: ExpansionDemo}, | ||
| {path: 'sticky-header', component: StickyHeaderDemo} |

Comments Addressed 👍 And @jelbourn , the gap between the headers when one starts pushing another is caused by the default spaces between two and the space is because there are spaces between |
| p { | ||
| text-indent: 4em; | ||
| margin-bottom: 1.5em; |
Contributor

As discussed, this margin-bottom is what's causing the space between the headers. You can use :not(:last-child) to avoid putting the margin on the last item in the list to prevent it.

👍 Cool!
Changed margin to padding in CSS style file to avoid the extra white space between two <div>s
