 * Hello,
    It’s come to my attention that some of the code used in making an iframe
   responsive is not valid HTML… What are your thoughts on these errors below, which
   I believe are caused by HTML generated by this plugin?
 * > Invalid html: Bad value “100%” for attribute “width” on element “iframe”: Expected
   > a digit but saw “%” instead. (Line 349)
   >  Invalid html: Bad value “100%” for
   > attribute “height” on element “iframe”: Expected a digit but saw “%” instead.(
   > Line 349) Invalid html: Attribute “webkitallowfullscreen” not allowed on element“
   > iframe” at this point. (Line 349) Invalid html: Attribute “mozallowfullscreen”
   > not allowed on element “iframe” at this point. (Line 349) Invalid html: The“
   > frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.(
   > Line 349)
 * I want my videos to be responsive, but ideally I’d like them to use valid code,
   too. I’ve seen some people suggesting putting the width=100% in a style attribute…
 * Thanks.
