Guide to Using Bootstrap Embed for Good Styling

Introduction to Bootstrap Embed

In the ever-evolving landscape of web development, creating content that is not only visually appealing but also responsive has become a paramount concern. Before the introduction of Bootstrap Embed, embedding external content such as slideshows and Videos, presented challenges related to responsiveness and consistent styling. Developers had to manually handle the styling and sizing of embedded content to ensure responsiveness across various screens.

In this comprehensive guide, we will delve deep into the intricacies of Bootstrap Embed, explore why iframes may pose responsiveness challenges, unravel Bootstrap’s responsive embed classes, and provide hands-on demonstrations for embedding videos and slideshows.

What is Bootstrap Embed?

The Bootstrap “Embed” utility provides a convenient way to insert videos, slideshows, or other embedded content into a webpage while ensuring responsiveness. This means that the embedded content will automatically adjust its size and scale appropriately on various devices, maintaining a consistent appearance.

The utility directly applies styling rules to specific HTML elements, namely <iframe>, <embed>, <video>, and <object>. These elements are commonly used for embedding multimedia content on websites.

Why is iframe not responsive?

An iframe, or inline frame, is an HTML element used to embed another document or webpage within the current HTML document. By default, an <iframe> element may not be responsive because it inherits its dimensions from the content it embeds. If the content inside the iframe has fixed width and height values, the iframe will also have those same dimensions, potentially leading to a lack of responsiveness.

Bootstrap Responsive Embed Classes.

Bootstrap provides a set of responsive embed classes to help developers create embedded content that adjusts to different screen sizes and maintains a consistent aspect ratio.

1. Embed Responsive Class

The .embed-responsive class is the main container for the responsive embed. It sets up the necessary styles for responsiveness.

It should be directly applied to a container tag such as a <div> that wraps the embedded content as shown below.

<div class="embed-responsive">
  <!-- Embedded content -->
</div>

2. Embed Responsive Item Class

The .embed-responsive-item class is then applied to the actual embedded content (e.g., an <iframe>). This class ensures that the content inside the container adheres to the responsive styling defined by the parent element.

<div class="embed-responsive">
  <iframe class="embed-responsive-item" src="xxx" allowfullscreen></iframe>
</div>

Where the src attribute is the URL or file path to the content to be embedded and allowfullscreen is to allow the iframe to activate fullscreen mode. Feel free to also add other attributes and an intrinsic ratio that’ll scale on any device.

3. Aspect Ratio Classes

Aspect ratio classes define the proportion between the width and height of the embed. Bootstrap provides several predefined aspect ratio classes, such as embed-responsive-16by9, embed-responsive-21by9 and embed-responsive-4by3.

These classes are applied to the same container as the .embed-responsive class.

<div class="embed-responsive embed-responsive-21by9">
  <!-- Embedded content -->
</div>

The aspect ratio classes or modifier classes that are used for responsive video are discussed below:

Aspect RatiosDescription
embed-responsive-16by9This class has a 16:9 aspect ratio
embed-responsive-21by9This class has a 21:9 aspect ratio
embed-responsive-4by3This class has a 4:9 aspect ratio

Embedding a Video in Bootstrap.

Now that you have an understanding of what Bootstrap responsive embed classes are, it’s time to embark on the adventure of embedding a video in Bootstrap.

This section will provide you with a step-by-step walkthrough, complete with code samples and a live demo, to seamlessly integrate videos into your web pages.

Next, we’ll take a look at the crucial importance of making these videos responsive, ensuring an enhanced user experience across various devices.

Step 1: Choose Your Video Source

Before delving into the embedding process, determine the source of your video. Whether hosted locally within your project or sourced from a platform like YouTube, Vimeo, or another streaming service, ensure you have the necessary video URL or file path ready.

Step 2: Set Up Your Bootstrap Environment

Make sure you have Bootstrap integrated into your project. You can include Bootstrap via a CDN in the <head> of your HTML file, installing it into your frontend framework, or downloading the Bootstrap assets and linking to your project locally.

Ensure that you have the required Bootstrap classes for embedding videos.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Slideshow</title>

    <!-- Bootstrap CSS via CDN -->
    <link
      rel="stylesheet"
      href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"
    />

    <!-- Local Bootstrap CSS -->
    <!-- <link rel="stylesheet" href="path/to/bootstrap.min.css"> -->
  </head>
  <body></body>
</html>

Step 3: Create a Container for Your Video

Set up a container to hold your embedded video. Bootstrap provides the .embed-responsive class for this purpose. Choose the aspect ratio that suits your design; commonly used ratios are 16:9 and 4:3. This class is strictly required.

<div class="embed-responsive embed-responsive-16by9">
  <!-- Your video will go here -->
</div>

Step 4: Embed the Video

Within the container, embed your video using the appropriate HTML element, usually <iframe> for external videos. Replace “your-video-source” with the actual URL or file source.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Bootstrap Embed</title>

    <!-- Bootstrap CSS via CDN -->
    <link
      rel="stylesheet"
      href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"
    />

    <!-- Local Bootstrap CSS -->
    <!-- <link rel="stylesheet" href="path/to/bootstrap.min.css"> -->
  </head>
  <body>
    <div class="embed-responsive embed-responsive-16by9">
      <iframe
        class="embed-responsive-item"
        src="https://www.youtube.com/embed/JH77WsDH8yY"
        allowfullscreen
      ></iframe>
    </div>
  </body>
</html>

The code snippet provided above demonstrates how to embed a YouTube video using the Bootstrap responsive embed method.

By incorporating the necessary HTML structure and the appropriate Bootstrap classes, the video can be responsively displayed on your webpage. The resulting output of this code is illustrated below.

Here is the same YouTube video embedded using the native iframe method without Bootstrap embed responsive class.

Step 5: Test Responsiveness

Preview your page in different viewports to test the responsiveness of the embedded video. Bootstrap’s responsive embed classes will automatically adjust the video size for optimal viewing on various devices.

Embedding a Slideshow in Bootstrap

Expanding upon the foundational knowledge acquired from this article in the realm of video embedding in Bootstrap. Let’s delve into the captivating world of incorporating slideshows using Bootstrap.

What are SlideShows?

Slideshows are a powerful and dynamic means of presenting multiple images or content engagingly in a slide format in a prearranged sequence.

In this section, we’ll explore the essential components, provide comprehensive code examples, and walk you through the process of creating responsive and visually appealing slideshows that will help you captivate your audience.

Understanding the Components

Before we embark on the practical demonstration, let’s familiarize ourselves with the key components involved in creating a Bootstrap slideshow:

  1. Carousel Component: Bootstrap offers a versatile Carousel component for building slideshows. The Carousel allows you to display a series of content items, usually images, in a rotating fashion.

  2. Carousel Indicators: These are small indicators representing each slide in the slideshow. Users can click on these indicators to navigate directly to a specific slide.

  3. Carousel Controls: Bootstrap provides built-in navigation controls (previous and next arrows) for users to manually navigate through the slides.

A Step-by-Step Guide to Build a Slideshow – with Code Examples

Below are steps to build a slideshow in Bootstrap, complete with code examples to help you along the way.
