Make search mobile friendly

[lokal-profil]

Search is currently not mobile friendly.

On clicking in input box these are zoomed in on, on unfocus there is however no zoom out.

Ideal would be a maximum zoom which fits the whole of searchheader and which resets the size to full window upon triggering a search (clicking search).

The standard <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /> doesn't work since the map then disapears.
