Question: Which way are arrows supposed to point on a tabbed web page? Towards the selection or towards the body of the selection? An awkward scenario seems to arise when a user selects another item and the arrow moves to point at nothing in particular when the arrow is pointing to the body. Is there a best practice?

Answer: 
Adding to [Will's answer](https://ux.stackexchange.com/a/64731), if you're looking for a non directional highlight, here is a great example from Google's material Design

**Material design guidelines on using Tabs**

> 
> The tab corresponding to the visible content is **highlighted**.
> 
> 
> Tabs are grouped together and the group of tabs are in turn **connected
>  with their content**.
> 
> 
> Keeping tabs adjacent to their content helps maintain the relationship
>  between the two, as too great a separation can introduce ambiguity

Option B is breaking the horizontal line between tabs and content. #it just feels unpleasant.

Option A is a complete menu plus an arrow dictating the flow direction telling you to read the content, feels good.

Maybe try another option C without arrows, but A is good.
