Write some Javascript and CSS to correct the display of a documentation page

I have a single webpage that represents an automatically generated API documentation, that needs revamping to look and work more professionally, particularly in navigation aspects. The main objective is to improve the way the page is navigated by JS and place the API examples and parameter maps into a TABs as sections, and style to reduce the number of table of content elements. In the file provided, and image displayed, there are currently only 3 API request functions in the list, but that is because I have removed over 20 to make the design process easier for you. If the following layout or similar could be replicated, that would be ideal: [login to view URL] Eventually the documentation will sit inside 2 pages, so needs a basic/common design: [login to view URL] [login to view URL] After the design is done I will implement into the above pages using ur provided CSS and Javascript and other changes to DOM structure where required so dont worry about the content, more the design of it. A standalone HTML mockup will be provided for you to edit and design in.
