CSS Scroll Snap used to be as soon as introduced to allow you to define snap problems for scrollable portions. It promises that the scrolling lands precisely at the desired problems.

This new CSS feature is especially useful for rising carousels, slideshows, or any construction where you want to regulate the individual’s scrolling enjoy. Let’s see how it works.

Table of Contents

New Houses

The CSS Scroll Snap module introduces two number one new homes to offer us additional regulate of the scrolling habits:

scroll-snap-type: This belongings is performed to the container phase to stipulate the snapping habits. It can be set to x, y, or every to specify the axis of snapping. It moreover takes a second argument which can be set to vital or proximity. The vital price forces the scroll to snap to the nearest snap degree, while proximity allows the scroll to forestall at any degree all over the snap area.
scroll-snap-align: This belongings is performed to the scrollable portions all over the container to stipulate the snap problems. It can be set to get began, center, or end to specify where the phase should snap to the container. It can be set to none to disable snapping for a decided on phase.

Creating Carousel

First, let’s say we wish to create a horizontal carousel of images. We would really like every image to slide and right away snap into place as we scroll it. First, we place the HTML, as follows:

<div class="carousel">
    <div class="slide">
        <img src="/image-1.jpg" width="600" best="400" />
    </div>
    <div class="slide">
        <img src="/image-2.jpg" width="600" best="400" />
    </div>
    <div class="slide">
        <img src="/image-3.jpg" width="600" best="400" />
    </div>
    <div class="slide">
        <img src="/image-4.jpg" width="600" best="400" />
    </div>
</div>

Along with the categories.

.carousel {
    display: flex;
    overflow-x: scroll;
    scroll-snap-type: x vital;
}

.image {
    flex: 0 0 100%;
    scroll-snap-align: center;
    
    /* Stylistic portions */
    width: 100%;
    best: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    font-size: 2rem;
    background-color: #dddddd;
}

In this example, we set the scroll-snap-type belongings to x vital on the .carousel container, indicating that the scroll snapping should happen horizontally and be vital. We moreover set the scroll-snap-align belongings to center on the .image portions, that suggests every image will snap to the center of the container as you scroll.

To make it scroll vertically, we will be able to simply set the scroll-snap-type price to y, and change the direction of our Flex construction so every phase would stack vertically.

.carousel {
    display: flex;
    flex-direction: column;
    overflow-y: scroll;
    best: 100vh;
    scroll-snap-type: y vital;
}

/* ...Ultimate code... */
