The easiest way to embed one of these maps on your site is to use an iframe. Below I have added an example of how it will look and below that I have included some code that you can simply copy and paste.
If you need any more help please email michael@gbmaps.com
The HTML you will need for an iframe
<iframe src="MAP_LINK" frameborder="0" class="gbm-map-embed"></iframe>
Simple CSS to style the iframe
iframe.gbm-map-embed {
width: 100%;
height: 800px;
}
