50projectsIn50days – Day 26: Vertical Slider

Vertical Slider is a project were you can flip the images vertically instead horizontally. For that reason the name.

The html has a fixed number of images which are loaded from Unsplash. There are two buttons. They are inside a div. Besides that, each one has its own div as you can see below:

      <div class="action-buttons">
        <button class="down-button">
          <i class="fas fa-arrow-down"></i>
        <button class="up-button">
          <i class="fas fa-arrow-up"></i>

In the slider container is the responsable of make give the slider container fit only with one image. As we can read in the documentation:

The height and width properties are used to set the height and width of an element.

CSS Height, Width and Max-width – w3schools

The buttons tagged as up and down are selected by the JavaScript and added an event listener:

const upButton = document.querySelector('.up-button')
const downButton = document.querySelector('.down-button')

upButton.addEventListener('click', () => changeSlide('up'))
downButton.addEventListener('click', () => changeSlide('down'))

Each time the event is clicked the function ChangeSlide the index adding or substracting depending if the user click the up arrow or the down arrow.
