Implementation

Introduction

In this resource we use the "Watch CSS" option of Flickity to control when the slider is on/off. There are multiple ways to initialized and control Flickity.

Slider Group

Your slider should be wrapped in an element with the attribute [data-flickity-type="cards"]. When having multiple Flickty sliders you can also use another attribute value here, for example [data-flickity-type="gallery"]. The script assigns each of these containers a unique ID and sets attributes to store the number of slides [data-flickity-count] and the active status [data-flickity-status].‍

Slider List

Inside the slider container, include an element with the attribute [data-flickity-list]. This is the element on which Flickity is initialized to display your slides.‍

Slider Slides

Each individual slide should have the attribute [data-flickity-item].

Previous/Next Buttons *optional

Previous Button: An element with [data-flickity-control="prev"] lets users navigate to the previous slide. The script automatically disables this button when the first slide is active.
Next Button: An element with [data-flickity-control="next"] lets users navigate to the next slide. This button is disabled when there are no more slides to show—especially considering the number of visible slides.

Dots / Pagination *optional

Place elements with the attribute [data-flickity-dot] as pagination controls.
When a dot is clicked, the slider moves to the corresponding slide (or the maximum valid slide, if multiple items are in view).
The script updates dots during slide changes so that the dot matching the active (or last valid) slide gets marked with [data-flickity-dot="active"]. This lets you style the active dot (e.g., change its background color) via CSS.

Multiple Sliders

The script is built to handle multiple slider groups on a single page. Each slider group is independently initialized with a unique ID, ensuring that their navigation controls and dot updates don’t interfere with one another.

Responsive Behavior

Viewport Columns

The number of slides visible at one time is controlled by the CSS custom property var(--flick-col) on the slider container. The gap can be set via var(--flick-gap) variable.

Enable/Disable Flickity with CSS

If the total number of slides is less than what’s visible, you can disable the slider via CSS. Conversely, when there are enough slides for the current viewport, you can re-enable it.

/* Desktop */
@media screen and (min-width: 992px) {
  [data-flickity-type="cards"] {
    --flick-col: 3;
    --flick-gap: 2em;
  }
  /* Turn Flickity OFF & Hide Controls */
  [data-flickity-type="cards"]:is([data-flickity-count="1"], [data-flickity-count="2"], [data-flickity-count="3"]) [data-flickity-list]::after {content:""; display: block;}
  [data-flickity-type="cards"]:is([data-flickity-count="1"], [data-flickity-count="2"], [data-flickity-count="3"]) [data-flickity-list] {display: flex;}
  [data-flickity-type="cards"]:is([data-flickity-count="1"], [data-flickity-count="2"], [data-flickity-count="3"]) [data-flickity-controls] {display: none;}
  [data-flickity-type="cards"] [data-flickity-dot]:nth-last-child(-n+2) {display: none;} /* Hide last two dots */
}
