How to place google maps into Blocs 2

How I place google maps into Block 2.3.0 ?

HTML widget

I have a website that works being built with Freeway Pro. I can’t get it working in Blocs.
I copied and pasted the code, but no luck.
here it is minus my Google key

Thanks is advance. (Pasting in a HTML widget Blocs 3.0)

html { height: 100% } body { height: 100%; margin: 0; padding: 0 } #map_canvas { height: 100% }
