Gmaps4rails will not display full width map <p>New to rails and doing my first trail with Gmaps4rails. I am trying to get a map to display in a bootstrap grid column, taking up the full height and width of the column. Any css method I use that results in width: 100%; height: 100%; results in the map not displaying. </p> <p>How can I get the map displaying at full width/height?</p> <p>One of my simple tests resulting in no map:</p> <pre><code>&lt;div class="col-xs-12 col-md-7"&gt; &lt;div id="map" style='width: 100%; height: 100%;'&gt;&lt;/div&gt; &lt;/div&gt; </code></pre>
