Responsive iframe using Bootstrap

问题:

I am using Bootstrap.

I have a text which contains 2 or 3 iframes based embed videos.

This data is fetched from database.

How can I make these iframes responsive?

Example Code:

<div class="row">

   <div class="col-lg-12 col-md-12 col-sm-12">

     SOME TEXT SOME TEXT SOME TEXT SOME TEXT
     SOME TEXT SOME TEXT SOME TEXT SOME TEXT

     <iframe src="http://youtube.com/...."></iframe>

     SOME TEXT SOME TEXT SOME TEXT SOME TEXT
     SOME TEXT SOME TEXT SOME TEXT SOME TEXT

     <iframe src="http://youtube.com/...."></iframe>


     SOME TEXT SOME TEXT SOME TEXT SOME TEXT
     SOME TEXT SOME TEXT SOME TEXT SOME TEXT

     <iframe src="http://youtube.com/...."></iframe> 

   </div>

</div>

This is a dynamic data. How can I make it responsive?

Option 1

With Bootstrap 3.2 you can wrap each iframe in the responsive-embed wrapper of your choice:

http://getbootstrap.com/components/#responsive-embed

<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="…"></iframe>
</div>

<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
  <iframe class="embed-responsive-item" src="…"></iframe>
</div>

Option 2

If you don't want to wrap your iframes, you can use FluidVids https://github.com/toddmotto/fluidvids. See demo here: http://toddmotto.com/labs/fluidvids/

   <!-- fluidvids.js -->
    <script src="js/fluidvids.js"></script>
    <script>
    fluidvids.init({
      selector: ['iframe'],
      players: ['www.youtube.com', 'player.vimeo.com']
    });
    </script>

The best solution that worked great for me is the one I found in the link below: https://bootstrapmaster.com/implement-responsive-youtube-vimeo-embed-iframe-twitter-bootstrap-3/

You have to: Copy this code to your main CSS file,

.responsive-video {
    position: relative;
    padding-bottom: 56.25%;
    padding-top: 60px; overflow: hidden;
}

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

and then put your embeded video to

<div class="responsive-video">
    <iframe ></iframe>
</div>

That’s it! Now you can use responsive videos on your site.

So, youtube gives out the iframe tag as follows:

<iframe width="560" height="315" src="https://www.youtube.com/embed/2EIeUlvHAiM" frameborder="0" allowfullscreen></iframe>

In my case, i just changed it to width="100%" and left the rest as is. It's not the most elegant solution (after all, in different devices you'll get weird ratios) But the video itself does not get deformed, just the frame.

Option 3

To update current iframe

$("iframe").wrap('<div class="embed-responsive embed-responsive-16by9"/>');
$("iframe").addClass('embed-responsive-item');
