Not the best solution, but if you go into
pronamic-google-maps -> classes
and open
Pronamic_Google_Maps.php
go to line 270 and
replace
$content .= sprintf(‘<div class=”canvas” style=”width: %dpx; height: %dpx;”>’, $info->width, $info->height);
with
$content .= sprintf(‘<div class=”canvas”>’, $info->width, $info->height);
Then you can control the size of the map in css either in percentage or pixels.
