The Ultimate ReactJS Image Carousel — Phase 1

Fully responsive; Mobile and Desktop; Button, Wheel, & Touch navigation.

This is Phase One of a Two-phase project where we build a fully responsive image carousel for mobile and desktop.

Browse our Teachable courses.

We’ll start by putting all of our elements on screen.

We need two components: Deck.js and Card.js

We have 7 elements to work with:

  • In the Deck.js
    1. a button for moving right (BUTTON)
    2. a button for moving left (BUTTON)
    3. a view port (DIV)
    4. an images container (DIV)
    5. a touch area that we’ll use to determine whether or not the user is allowed to scroll the carousel (DIV)
  • In the Card.js
    6. a ”card” which we’ll use to hold the image (DIV)
    7. the actual image (IMG)

We’ll use a combination of absolute positions and transforms.

We write a simple function that determines the middle card of our deck and moves the cards to the left of that middle to the left and the cards to the right of that middle to the right.

Let’s discuss RESPONSIVE.

To make our carousel responsive, we need to resize our view port based on percentages and not hard pixel units.

So we’ll just pick 50% and calculate a hard pixel count based on the width of the user’s browser window; then we’ll run this code in a resize window event listener.

window.addEventListener('resize', () => {
img_width_as_percentage = 50;
// img_width_as_percentage = window.innerWidth < 768 ? 100 : img_width_as_percentage;
this.new_width =
/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ?
(img_width_as_percentage / 100) * window.screen.width :
(img_width_as_percentage / 100) * window.innerWidth; = `${this.new_width}px`;this.order_cards();

We have our elements laid out and ready to go.

In the next phase, we’ll start moving this thing with touch, button, and wheel navigation.
