How to add spaces between Slick carousel items

Maintaining central alignment

With borders added to the .slick-slide items, your carousel might need some help staying in the center. Use negative margins on the .slick-list to counterbalance your slide margins:

.slick-list {
    /* Leveling the seesaw */ 
    margin-left: -5px; 
} 
.slick-slide {
    /* Life in space */ 
    margin-right: 10px; 
}


Ensuring responsive design

Your item spacing should be responsive, adapting smoothly to different viewport sizes. Achieve this by assigning percentage-based margins or using media queries:

.slick-slide { 
    /* Spacing? It's relative */
    margin-right: 2%; 
}


Or, for more meticulous control:

@media (max-width: 768px) {
    .slick-slide { 
        margin-right: 5px; 
    }
}
@media (min-width: 769px) {
    .slick-slide { 
        margin-right: 10px;
    }
}


Alleviating alignment oddities

Occasionally, slide margins make your carousel lose its alignment. Offset this by adjusting the slidesToShow property or applying left margin to .slick-track:

.slick-track { 
    /* A slight shuffle to the left */
    margin-left: -10px; 
}


Retaining interactive content

Spacing may block click events, especially when interactive content lies near the edge of the container. Use pointer-events in your CSS to ensure carousel items can still interact:

.slick-slide:not(.slick-active) {
    /* Only interact when you're in the spotlight */ 
    pointer-events: none;
}
.slick-active {
    pointer-events: auto;
}


Advanced spacing strategies

Want to venture further into the carousel cosmos? Here are some more techniques:

Conditional item spacing

For conditional spacing between specific items, apply CSS selectors:

.slick-slide:not(:last-child) { 
    /* Last child enjoys all the space */
    margin-right: 10px; 
}


Responsive container size

Different-sized items may need a responsive container. Utilize Flexbox inside the .slick-slide to manage variable content sizes while keeping consistent legal spacing:

.slick-slide { 
    display: flex; 
    justify-content: center; 
}


Gradient borders for spacing

For visual flair, use CSS gradients as item dividers:

.slick-slide {
    /* Blending a bond of modern art in middle space */
    background: linear-gradient(90deg, transparent, transparent 10px, #eaeaea 10px, #eaeaea 11px, transparent 11px);
}


Counteracting scroll overflow

Margins may cause overflow, resulting in unintended horizontal scroll. Apply overflow:hidden to the carousel container to keep scroll in check:

.carousel-container { 
    /* Overflow fashion statement? I don't think so. */
    overflow: hidden; 
}
