I am developing an HTML5 web app that is mostly being used on mobile devices. It's basically a link discovery app: It shows the user some hopefully interesing links, which the user then can visit. I would like to keep the user in our app though, so that our menu bar always remains at top.

Standard links of course take the users away from our page completely, with no option to return:

```
<a href="https://rads.stackoverflow.com/amzn/click/com/1561455954" rel="nofollow noreferrer">The Cheshire Cheese Cat</a>

```

`frames` and `iframes` are discouraged in HTML5. What other options are there?

(What we try to achieve is similar to what Facebook or Twitter are doing. Lots of links are being passed around there, which the user can visit. But he alsway can go back to his news feed, with the Facebook or Twitter menu bar.
