I read doc of docsify, it mentions that we can use topMargin to configure the space on top when scrolling the content page to reach the selected section. I try to use it to configure my page, but i failed to let navbar fix on the top of the page. it still scroll as the page goes up.
It mention that as we use sticky-header it is useful, but i wonder how to use sticky-header. It doesn't appear on the doc.
The doc goes here: topMargin
