Create Image Slider With Navigation Buttons Using HTML, CSS & JS

#html #css #webdev #javascript

Today in this blog I'll share the image slider effect using HTML, CSS & javascript.
I'm sure that you have seen the Image Slideshow Effect on many websites. A slide show is a presentation of a series of still images on a projection screen or electronic display device, typically in a prearranged sequence.

In the video, you have seen the image slider effect and I hope you've understood the basic codes behind creating this slider.

HTML Code:



    <div class="slider-ctr">
        <figure class="slide"><img src="dori.jpg" alt="Sky"/>
          <figcaption> 
            <div class="title">Doraemon</div>
            <div class="author">Doraemon and Nobita</div>
          </figcaption>
        </figure>



        <figure class="slide"><img src="vim.jpg" alt="Sky"/>
          <figcaption> 
            <div class="title">Bheem</div>
            <div class="author">Chota Bheem</div>
          </figcaption>
        </figure>



        <figure class="slide"><img src="oggy.jpg" alt="River"/>
          <figcaption> 
            <div class="title">Oggy</div>
            <div class="author">Oggy and the Cockroaches</div>
          </figcaption>
        </figure>


        <figure class="slide"><img src="tom.jpg" alt="Rain"/>
          <figcaption>
            <div class="title">Tom</div>
            <div class="author">Tom and Jerry</div>
          </figcaption>
        </figure>


        <figure class="slide text-on"><img src="jan-book.jpg" alt="Ocean"/>
          <figcaption>
            <div class="title">Mowgli</div>
            <div class="author">The Jangal Book</div>
          </figcaption>
        </figure>


        <div class="slider-control">
          <div class="control prev disabled">
            <div class="fa fa-chevron-left"></div>
          </div>

          <div class="control next">
            <div class="fa fa-chevron-right"></div>
          </div>
        </div>
      </div>
