Responsive Video or Slideshow Embeds in Bootstrap with Examples

BootstrapWeb DevelopmentFront End Technology

Bootstrap is a free open source and is one of the most famous HTML, CSS, and Javascript frameworks. It's used for user interfaces and themes that create what a user sees in a website or application, and it's utilized on the client rather than the server.

Responsive web applications automatically adapt to various screen sizes. It is used to create responsive mobile-first web apps and websites; mobile-first refers to designing for smaller displays first and then scaling up to bigger ones. As a result, you won't have to worry about your app not working on different devices or with different screen sizes.

In Bootstrap we have a class named “embed-responsive” for creating embeds. Written rules are directly applied to elements of parent class i.e <iframe>, <embed>, <video>, and <object> elements.

Example

        <embed class="embed-responsive-item" src="https://www.youtube.com/embed/NAEHbzXMNpA" allowfullscreen>
        </video>
    </div>
</body>
</html>

Below is the result of the Above Code

To modify the Aspect ratio we have some modifier classes provided by Bootstrap.

<!-- Aspect ratio 1:1>
<div class="embed-responsive embed-responsive-1by1"></div>

<!-- Aspect ratio 4:3>
<div class="embed-responsive embed-responsive-4by3"></div>

<!-- Aspect ratio 16:3>
<div class="embed-responsive embed-responsive-16by9"></div>

<!-- Aspect ratio 21:9>
<div class="embed-responsive embed-responsive-21by9"></div>
