Max-width and Google maps

A small but interesting bug that had us stumped at first but once we stopped swearing we figured out max-width and maps don't mix.

On our Agencms site, we plot property results on a Google map and we also use the lovely CSSGrid to provide a dynamic layout. However, one of the simple styles kept breaking Google maps (see screenshot).

It turns out that one of the default CSS rules in the CSSGrid (and many reset / responsive frameworks) is that it sets the CSS rule

img, object, embed { max-width: 100%; }

This is fine except it seems to also impact on the controls if you use embedded maps. As such, you just need to provide a specific override for images within your map holder to cancel the 100% setting. This can be done simply by using:

#map-holder img { max-width: none; }

Hooray! fixed maps

Hope that helps someone!
