Slick slider centerMode

Question

I've been trying to create something like this using slick.js, and i really can't get my head around it.

I have got the current code in place. How to make the center slide image 100% width and height and add paddings to the slide? It seems to be not working.

I'd really appreciate any help. Thanks.

$('.slider').slick({
  centerMode: true,
  centerPadding: '30px',
  slidesToShow: 3,
  adaptiveHeight: false
});

.slick-slide img {
  max-width: 100%; 
  transition: transform 0.5s; 
 }

.slick-slide.slick-center img{
  transform: scale(2.1);
}

Solution

A little bit of CSS should help you out:

$('.slider').slick({
  centerMode: true,
  centerPadding: '30px',
  slidesToShow: 3
});

.slick-slide > div {
  transform: scale(.5);
  transition: transform .3s cubic-bezier(.4,0,.2,1);
}
.slick-center > div {
  transform: scale(1);
}
.slider__item > img {
  width: 100%;
  height: auto;
}

<div class="slider">
  <div class="slider__item">
    <img src="https://pp.userapi.com/c849132/v849132998/45c5c/RSTineyyvfE.jpg" alt="">
  </div>
  <div class="slider__item">
    <img src="https://pp.userapi.com/c849132/v849132998/45c5c/RSTineyyvfE.jpg" alt="">
  </div>
  <div class="slider__item">
    <img src="https://pp.userapi.com/c849132/v849132998/45c5c/RSTineyyvfE.jpg" alt="">
  </div>
  <div class="slider__item">
    <img src="https://pp.userapi.com/c849132/v849132998/45c5c/RSTineyyvfE.jpg" alt="">
  </div>
  <div class="slider__item">
    <img src="https://pp.userapi.com/c849132/v849132998/45c5c/RSTineyyvfE.jpg" alt="">
  </div>
  <div class="slider__item">
    <img src="https://pp.userapi.com/c849132/v849132998/45c5c/RSTineyyvfE.jpg" alt="">
  </div>
</div>

The principle is simple: use transform: scale(n) to scale down all the slides (where n is your desired factor - .5 in the example above). use transform:scale(1) on the centered one (has .slide-center class) to render it at its real scale (1:1).
And add a transition on transform.

Done.
