The interactive presentation is what makes a statement these days. Everything static is boring. Therefore, web developers delight the online crowd with a sheer diversity of dynamic solutions. If your website does not have much space but you want to deliver lots of information, then javascript carousels are just irreplaceable. No one likes to read long pages. With a compact and neat structure, carousels help to create a comfortable user experience. There are many ways to create a slider. You can use Bootstrap, jQuery plugins, or simply build everything as a javascript carousel.

How to Create Carousel using Javascript

Here is a quick tutorial on creating a javascript carousel slider.

1. When it comes to creating a javascript carousel, it is best to start with a concept. Determine why the slider is the best fit for your content, instead of a standalone image or video. With this question answered, you will have a good sense of the type of content you plan to use. Sketch out a storyboard to get an idea of how many frames you will need. Decide if your javascript carousel will jump from one image to the next, or have a continuous, panoramic effect. You can also use popular tools like Mockitt to sketch the storyboard.

2. Use HTML to define the content of the carousel. In this example we use img to add images. However, you can also choose to use div to define the carousel content.

<ul> <li><img class="img1" src="//picsum.photos/300/200?1"></li> <li><img class="img2" src="//picsum.photos/300/200?2"></li> <li><img class="img3" src="//picsum.photos/300/200?3"></li> <li><img class="img4" src="//picsum.photos/300/200?4"></li> <li><img class="img5" src="//picsum.photos/300/200?5"></li> <li><img class="img6" src="//picsum.photos/300/200?6"></li> <li><img class="img7" src="//picsum.photos/300/200?7"></li> <li><img class="img8" src="//picsum.photos/300/200?8"></li> <li><img class="img9" src="//picsum.photos/300/200?9"></li> </ul>

3. Define the styling for the carousel content –

ul { display: flex; margin: 0; padding: 0; overflow: hidden; } li { display: block; list-style: none; }

There could be other possible ways to import the jQuery image slider plugin and this varies from one plugin to another.

4. Add buttons to the carousel by adding the requisite navigation controls in HTML

<button onclick="show(-1)"><</button> <button onclick="show(+1)">></button> <style> display: flex; font-size: 32px; align-items: center; justify-content: center; color: #FFF; background-color: #333; border-radius: 50%; width: 44px; height: 44px; } button.prev { } button.next { position: absolute; right: 0; top: 80px; } </style>

5. Add the required javascript functions to add the scroll animation.

let liEls = document.querySelectorAll('ul li'); let index = 0; window.show = function(increase) { index = index + increase; index = Math.min(Math.max(index,0), liEls.length-1); liEls[index].scrollIntoView({behavior: 'smooth'}); }

6. The good thing about this is that this technique is not limited to images, but you can use it for all types of list with different width and heights.

7. Note that you can also use reusable javascript carousel plugins to reduce the coding overhead. Bootstrap also offers various simple options to quickly create a javascript carousel.

Designers love to focus on creative ideas and experiments. Rarely do you find a designer who loves to play with HTML, CSS and javascript. However, from a designer's perspective it is also imperative to perform a seamless handoff to developers. On the other hand, it can be quite complex for a developer to manually look at a wireframe and code the javascript carousel. When specifications are manually called out, there is bound to be significant human error.
