Tabs isn't working and Visual Video on a phone

Hello, I bought your boldial theme for my wordpress. But I have two problems I can not solve.
First, for 4 days, when I look at the site on a phone there is a red line that goes, and the theme is no longer aligned. When I delete the video there is to open the site, the red area disappears. But initially it did not make it, even with the video. Video is seen correctly in all media, but not when looking at the site with a phone vertically

Second, since 4 days also, I can not click buttons for the biography either in English or in French in the “tabs” that I created. It worked perfectly before

I do not know anything about code (or almost), then I do not solve problems. My website is not online yet, I send you the answer in private access

Can you help me please?
