Video Issues On Mobile Display

Hello, Video is not responsive on mobile display from WordPress page. Not sure if this is an issue with the theme. Either way, can you assist with some CSS code to get the video to render correctly when viewed on Mobile? It needs to be a little wider on the screen, so if it can display full width, I think the issues will self correct. You can view it here: https://iglobal.net/welcome-to-iglobal/ When I turn the phone sideways it works fine, but hen I hold the phone vertically, the play button and then pause button cover up the content. Also, there are issues at the end of the video with displaying the CTA page ecetra. Can you assist? I would appreciate it, it would be so much easier then rolling the dice on the WordPress help forum. Thanks for your consideration. Edwin
