Styling

Now it’s time to style our page. Since you are building an image slider, we will be assuming that you have a basic understanding of CSS.

Currently, the side display property is set to none. We will use a little bit of JavaScript to add the functionality and the timer.

Now we will style the navigation buttons and dots.

Javascript

The ‘currentSlide’ variable is used to store the index of the current slide.

The function next () is used to change the current slide to the next slide. The function checks if the current slide is greater than or equal to the last index of the slide, which is an array. If it is true, we reset it to zero.

The prev () function is used to check if the ‘currentSlide’ variable is less than or equal to zero.

The next () function is used to change the slide automatically after 5 secs.
