scroll-snap-coordinate

Thescroll-snap-coordinate CSS property defines the x and y coordinate positions within an element that will align with its nearest ancestor scroll container's scroll-snap-destination for each respective axis.

/* Keyword value */
scroll-snap-coordinate: none;

/* <position> values */
scroll-snap-coordinate: 50px 50px;                   /* Single coordinate */
scroll-snap-coordinate: 100px 100px, 100px bottom;   /* Multiple coordinates */

/* Global values */
scroll-snap-coordinate: inherit;
scroll-snap-coordinate: initial;
scroll-snap-coordinate: unset;

If the element has been transformed, the snap coordinates are likewise transformed, thus aligning the snap points with the element as it is displayed.

Syntax

Values

none

Specifies that the element does not contribute to a snap point.

<position>

Specifies the offset of the snap coordinates from the start edge of the element’s border box. For each pairing, the first value gives the x coordinate of the snap coordinate, the second value its y coordinate.

Formal syntax

none | <position>#
where 
<position> = [ [ left | center | right ] || [ top | center | bottom ] | [ left | center | right | <length-percentage> ] [ top | center | bottom | <length-percentage> ]? | [ [ left | right ] <length-percentage> ] && [ [ top | bottom ] <length-percentage> ] ]
where 
<length-percentage> = <length> | <percentage>

Example

HTML

<div id="container">
  <div>
    <p>At coordinate (0, 0)</p>
    <div class="scrollContainer coordinate0">
      <div>1</div>
      <div>2</div>
      <div>3</div>
    </div>
  </div>

  <div>
    <p>At coordinate (25, 0)</p>
    <div class="scrollContainer coordinate25">
      <div>1</div>
      <div>2</div>
      <div>3</div>
    </div>
  </div>

  <div>
    <p>At coordinate (50, 0)</p>
    <div class="scrollContainer coordinate50">
      <div>1</div>

      <div>3</div>
    </div>
