I recommend that the content fo a single HTML Spring Cloud document should be on the left side of the page. It is more readable.
The Spring boot document is a good example.
https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/
The content is fixed on the left side, following the scrolling of the document, and is expanded step by step.
