Bootstrap Carousel

If you’re here, you probably know already what the deal with Bootstrap is. But just in case, before going over our subject — Bootstrap Carousels — let’s go over what this framework can do and most of the time do great.

 

Brief Intro

Bootstrap is an open source web development framework that does wonders when it comes to designing mobile-friendly, responsive web pages.

As you’ve probably already guessed, we are huge fans of Bootstrap and if you’re wondering why let me just give you several reasons:

  • 4–5 hours of learning Bootstrap from the official site is all it takes for you to be able to start using it and loving it
  • Very customizable
  • Consistency across devices
  • Using Bootstrap is so much easier than using Pure CSS media queries
  • Super fast development

Let us now talk about building one of the Stars of Bootstrap, also known as…

 

The Bootstrap Carousel

Simple Bootstrap Carousel

The carousel is a component that enables cycling through content(images, text, custom markup). You can include it using the Bootstrap carousel.js file or the whole bootstrap.js / bootstrap.min.js file.

Here’s the basic code for building this ‘Pug Carousel.’

<div id="pugCarousel" class="carousel slide" data-ride="carousel">
<!-- Carousel Slides -->
    <div class="carousel-inner">
      <div class="item active">
        <img src="https://goo.gl/6Xf9NY" alt="First pug wrapped in a blanket" style="width:100%;">
      </div>
<div class="item">
        <img src="https://goo.gl/tD3tz2" alt="Second pug wrapped in a blanket" style="width:100%;">
      </div>
<div class="item">
        <img src="https://goo.gl/K4NJsk" alt="Third pug wrapped in a blanket" style="width:100%;">
      </div>
    </div>
    </div>

Next, let’s see what the classes and attributes you can use with the carousel are.

 

Analyzing the Bootstrap Carousel classes

  • .carousel creates the carousel
  • .slide adds the transition effect. It is not mandatory.
  • .carousel-inner adds the slides
  • .item for the content of each slide
  • .left carousel-control .right carousel-control add the left/right button to the carousel that enable the user to navigate between slides
  • .icon-next .icon-prev for unicode arrow icons that point right/left
  • .carousel-caption inserts captions

 

Analyzing the data- Attributes

  • data-ride = “carousel“ activates the carousel
  • data-slide (that accepts the prev or next value)& data-slide-to (that accepts number values) specifies the slide to lead to

 

Examples of class & data- attribute usage

  • adding controls
<div class="container">
  <h2 style="color:tomato; text-align: center; padding: 5px;">The Pug Carousel</h2>
  <div id="pugCarousel" class="carousel slide" data-ride="carousel">
<!-- Carousel Slides -->
    <div class="carousel-inner">
      <div class="item active">
        <img src="https://goo.gl/6Xf9NY" alt="First pug wrapped in a blanket" style="width:100%;">
      </div>
<div class="item">

      </div>
<div class="item">
        <img src="https://goo.gl/K4NJsk" alt="Third pug wrapped in a blanket" style="width:100%;">
      </div>
    </div>
<!-- Carousel Controls -->
    <a class="left carousel-control" href="#pugCarousel" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span> 
    </a>
    <a class="right carousel-control" href="#pugCarousel" data-slide="next">

Conclusions & further steps

Overall, building this kind of carousel should be easy enough for almost anybody. And it probably would not take more than half an hour to develop (unless you’re like me and spend 3 hours finding the perfect pug pictures).

There are still things you can learn about Bootstrap Carousels such as options and methods.

We’ll leave you with this short tutorial for now and if you find it useful enough, we’ll certainly take it a step further in another article. Just tell us in the comments!

  1. Hi there. I have recently been digging deep into bounce rates and design related issues and strangely enough it seems the statistics for carousels in particular show a greater number of bounced users on a website. I mean on my own website i still use a carousel / slider bit i have taken it off auto to let users decide whether they want to see the next slide. Learning about a carousel however can save you from using many plugins and jquery scrips and save you alot of page speed.

    And i have to laugh at your one comment, finding images is always the worst part of anything in design i love it, but man i get so picky it takes time.
