How to move a map using Map press easy Google plugins

I'm currently building a website using wordpress. I used Map press easy Google plugins for include a map in my contact tab. However, I want to put for example the map to the left and a form to the right. But I don't find any features which can allow me to move it. I tried to use the .css file but I don't have any html take to select. Here is my website with my map:

and here's the code provide by the plugin that I insert into my contact page:

[mappress mapid="1"]

Does who is using this plugin can help me ? Thank's
