if base theme uses img max-width, google maps in civic become unusable

It is becoming more and more common to define an img

{max-width }

css rule in Drupal/Wordpress themes to get responsive design (seemlessly transitioning from desktop -> tablet -> mobile). Which is all well and good until you try to use google map tiling, which makes use of images that overflow their divs for many of the controls.

I suggest adding the following css line to civicrm:

#Map img

{ max-width: none; }

Which ensures max-width is reset for the image on the map section of civicrm.
