CI3 User Guide Style

Job well done. Like it, but ...

I miss the complete overview from the old docs. OK, I have to get over that.

As @orionstar pointed out there needs to be a table of content on the longer pages for easier navigation and overview. Doesn't have to be visible all the time. One click away would be acceptable.

Also the general menu shouldn't scroll out of sight. It could stop scrolling with the content when the bottom of the menu becomes visible. It could then scroll upwards with the content until the top of the menu becomes visible. Thus it would always be visible.

The table of content on long pages would benefit from two columns on wide screens.

I'm having an issue with the colors of the menu. It's grey on dark, dark on white and grey on grey. Stick to one of lighter on darker or darker on lighter and then only make minor variations.

When screen width is just above the break point where the menu is hidden the menu is ridiculously wide. The design would benefit from a more narrow menu.

That's my two cents!
