Bootstrap is always changing, if you have an old code, embeding a YouTube video might not work.
But there is an easy fix, you can manually add the code resposible for embed YouTube videos in your page.
Here is the css code.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | <style> .embed-responsive { position: relative; display: block; height: 0; padding: 0; overflow: hidden; } .embed-responsive .embed-responsive-item, .embed-responsive iframe, .embed-responsive embed, .embed-responsive object, .embed-responsive video { position: absolute; top: 0; bottom: 0; left: 0; width: 100%; height: 100%; border: 0; } .embed-responsive-16by9 { padding-bottom: 56.25%; } </style> |
And here is the html code that can work as an example for your embeded video.
2 3 4 5 6 7 8 | <div class="row"> <div class="col-xs-12 col-md-12"> <div class="embed-responsive embed-responsive-16by9"> <iframe class="embed-responsive-item" src="https://www.youtube.com/embed/sCUt1BvAlYM"></iframe> </div> </div> </div> |
