How add spaces between Slick carousel item

I want to add space between two slick carousel items, but not want the space with padding, because it's reducing my element size(and I don't want that).

    $('.single-item').slick({
        initialSlide: 3,
        infinite: false
    });

.slick-slider {
    margin:0 -15px;
}
.slick-slide {
    padding:10px;
    background-color:red;
    text-align:center;
    margin-right:15px;
    margin-left:15px;
}

<div class="container">
    <div class="row">
        <div class="col-sm-12" style="background-color:gray;">
            <div class="slider single-item" style="background:yellow">
                <div>1</div>
                <div>2</div>
                <div>3</div>
                <div>4</div>
                <div>5</div>
                <div>6</div>
            </div>
        </div>
    </div>
</div>

Somehow I am getting space from both side, I am trying to remove that.

  /* the slides */
  .slick-slide {
      margin: 0 27px;
  }

  /* the parent */
  .slick-list {
      margin: 0 -27px;
  }

This problem reported as issue (#582) on plugin's github, btw this solution mentioned there too, (https://github.com/kenwheeler/slick/issues/582)

The slick-slide has inner wrapping div which you can use to create spacing between slides without breaking the design:

.slick-list {margin: 0 -5px;}
.slick-slide>div {padding: 0 5px;}

Since the latest versions you can simply add a margin to your slides:

.slick-slide {
  margin: 0 20px;
}

There's no need for any kind of negative margins, since slick's calculation is based on the elements outerHeight.

@Dishan TD's answer works nice, but I'm getting better results using only margin-left.

And to make this clearer to everyone else, you have to pay attention to the both opposite numbers: 27 and -27

  /* the slides */
  .slick-slide {
    margin-left:27px;
  }

  /* the parent */
  .slick-list {
    margin-left:-27px;
  }

An improvement based on the post by Dishan TD (which removes the vertical margin as well):

  .slick-slide{
    margin-left:  15px;
    margin-right:  15px;
  }

  .slick-list {
    margin-left: -15px;
    margin-right: -15px;
    pointer-events: none;
  }

Note: the pointer-events was necessary in my case, to be able to click on the left arrow.

Yup, I have found the solution for dis issue.

• Create one slider box with extra width from both side( Which we can use to add item space from both sides ).

• Create Inner Item Content with proper width & margin from both sides( This should be your actual wrapper size )

• Done

Just fix css:

/* the slides */
.slick-slider {
    overflow: hidden;
}
/* the parent */
.slick-list {
    margin: 0 -9px;
}
/* item */  
.item{
    padding: 0 9px;
}

simply add padding on to the slick-side class will do

.slick-slider .slick-slide {
  padding: 0 15px;
}

With the help of pseudo classes removed margins from first and last child, and used adaptive height true in the script. Try this fiddle

One more Demo

 $('.single-item').slick({
        initialSlide: 3,
        infinite: false,
        adaptiveHeight: true
    });

For example: Add this data-attr to your primary slick div: data-space="7"

                    $('[data-space]').each(function () {
                        var $this = $(this),
                            $space = $this.attr('data-space');

                        $('.slick-slide').css({
                            marginLeft: $space + 'px',
                            marginRight: $space + 'px'
                        });

                        $('.slick-list').css({
                            marginLeft: -$space + 'px',
                            marginRight: -$space/2 + 'px'
                        })
                    });

Add

centerPadding: '0'

Slider settings will look like:

$('.phase-slider-one').slick({
     centerMode: true,
     centerPadding: '0',
     responsive: [{breakpoint: 1024,},{breakpoint: 600,},{breakpoint: 480,}]
});

Thank you

Try to use pseudo classes like :first-child & :last-child to remove extra padding from first & last child.

Inspect the generated code of slick slider & try to remove padding on that.

Hope, it'll help!!!

If you want a bigger space between the slides + not to decrease the slide's width, it means you'll have to show less slides. In such case just add a setting to show less slides

    $('.single-item').slick({
      initialSlide: 3,
      infinite: false,
      slidesToShow: 3
    });

Another option is to define a slide's width by css without setting to amount of slides to show.

This approach works with the latest version of react-slick:

  .slick-list {
    margin: 0 -7px !important;
  }
  
  .slick-slide > div {
    padding: 0 7px !important;
  }

function slickSpacing(space, self){
    self.find('.slick-slide').css({
        marginLeft: space + 'em',
        marginRight: space + 'em'
    });
    self.find('.slick-list').css({
        marginLeft: -space + 'em',
        marginRight: -space/2 + 'em'
    });
}
function slickSlider(){
    $('.slick-slider').each(function () {
        var self = $(this);
        // var screenSize = String(self.attr('data-md')).match(/screen=([0-9]+)/);
        var spaceDefaultSize = String(self.attr('data-default')).match(/space=([0-9]+)/);
        var spaceSmSize = String(self.attr('data-sm')).match(/space=([0-9]+)/);
        var spaceMdSize = String(self.attr('data-md')).match(/space=([0-9]+)/);
        var spaceLgSize = String(self.attr('data-lg')).match(/space=([0-9]+)/);
        var spaceXlSize = String(self.attr('data-xl')).match(/space=([0-9]+)/);
        var spaceXxlSize = String(self.attr('data-xxl')).match(/space=([0-9]+)/);
        if(String(spaceDefaultSize) !== "null"){
            if($(window).innerWidth() >= 0){
                slickSpacing(spaceDefaultSize[1], self)
            }
        }
        if(String(spaceSmSize) !== "null"){
            if($(window).innerWidth() >= 576){
                slickSpacing(spaceSmSize[1], self)
            }
        }
        if(String(spaceMdSize) !== "null"){
            if($(window).innerWidth() >= 768){
                slickSpacing(spaceMdSize[1], self)
            }
        }
        if(String(spaceLgSize) !== "null"){
            if($(window).innerWidth() >= 992){
                slickSpacing(spaceLgSize[1], self)
            }
        }
        if(String(spaceXlSize) !== "null"){
            if($(window).innerWidth() >= 1200){
                slickSpacing(spaceXlSize[1], self)
            }
        }
        if(String(spaceXxlSize) !== "null"){
            if($(window).innerWidth() >= 1400){
                slickSpacing(spaceXxlSize[1], self)
            }
        }
    });
}
$(window).on('resize load', function(){
    slickSlider();
});

<div class="service-slider overflow-hidden" data-default="[space=1]" data-xl="[space=5]">
    <div></div>
    <div></div>
    <div></div>
</div>

.slick-slide > div {
  margin: 0 10px;
}
.slick-list {
  margin: 0 -10px;
