this code snippet looks pretty standard 
it's your run-of-the-mill web page that's just trying to get its stuff out there i mean, we've all seen this before: header with meta tags, main content area, and some js files thrown in for good measure 
if you're worried about performance or security, maybe look into minifying those js files a bit or using a CDN? also, accessibility-wise, make sure that video thumbnails are accessible for people who can't see 'em

! this html code looks like a mess 
. first off, the header section is all over the place 
. shouldn't it just say what browser/s device it's for? and whats up with so many external scripts? 
but wut about accessibility? 
also what if someone tries to use it and gets an error cuz of all these scripts? 
i mean what if someone wants to use this on a tablet or laptop with a smaller screen? the layout would be all messed up
