Last but not least, we need to remove the header from Swagger UI. The header has a CSS class of topbar. Therefore, to remove the header from our page, we can simply inject the following CSS into the header of our page.

<style>.topbar { display: none; }</style>

To do that, we will search for the </head> closing tag within docs/dist/index.html, and insert a newline above it with our own style tag. These steps can be achieved with one simple sed script. Add it at the end of scripts/swagger-ui/format.sh:

sed -i '/<\/head>/i \
<style>.topbar { display: none; }<\/style>' docs/dist/index.html

Run yarn run docs:update && docs:serve once more. Now, our page will not display the header any more!

Once you're happy with the changes, commit them and merge it back to the dev and master branch.
