I have on my page zaybee.pl problem with youtube iframes, when you look at the small window at the posts with youtube, everything works great - youtube width change to the width of window:
But on mobile phone (Android, Google Chrome) iframe is bigger then the rest of webpage:
Rest of elements on page have good width. On a desktop testers how page look on mobile everything looks good. I don't know where is problem.
My pieces of code:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>
<div class="ytframe"><iframe width="100%" height="364" style="position:relative;z-index:100;" src="http://www.youtube.com/embed/'.$src['v'].'?wmode=transparent" frameborder="0" allowfullscreen></iframe></div>
.ytframe {width:calc(100% - 77px);height:400px;position:relative;}
