问题 Currently I'm embedding Youtube videos with the following HAML code in a Twitter Bootstrap based site: .row .span12 %iframe.span11{ :height => "720", :frameborder => "0", :allowfullscreen => nil, :src => v.video_url } Unfortunately, this doesn't respond well when resizing the browser or on mobile devices because of the static height.
