I enclose the video iframe in a div.

<div class=youtube-container>
     <iframe src="https://www.youtube.com/embed/MRk5HynHe44" frameborder="0" allowfullscreen></iframe>
</div>

I use some CSS to make that div responsive such that it is wide as it can be, and always maintains the 16:9 aspect ratio. Then I use CSS to make the YouTube iFrame take up the whole container:

.youtube-container {
    width: 100%;
    position: relative;
    padding-bottom: 56.25%;
    height: 0;
    overflow: hidden;
}

.youtube-container iframe,.youtube-container object,.youtube-container embed {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

  • Can You explain me any thing about code: .youtube-container iframe,.youtube-container object,.youtube-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } – Master Prons Mar 9 '15 at 10:48
  • That is what causes the iframe to take up the entire container. Because the only way to maintain aspect ratio in CSS is to use padding, the contents of the container wouldn't show unless they overlapped that padding. To do so, it uses absolute positioning relative to the container. – Stephen Ostermiller Mar 9 '15 at 10:57
  • Thank You So much, one more help I want i.e. I want to reduce youtube-container width 90% instead of 100. I change it and also set margins of 5% at left and right but it showing extra space at left side and it also going from up side of my header which is fixed in css. Please, Guide me. – Master Prons Mar 9 '15 at 11:07
  • Set the width to 90% and then the left and right margin to auto: margin: 0 auto; – Stephen Ostermiller Mar 9 '15 at 12:43
  • I believe HTML5 iframe border="0" is obsolete and will fail w3c validation. So a quick fix for that would be using CSS iframe{border:0;}. – Simon Hayter Mar 9 '15 at 13:55
