To add responsive image sizes when using Slick for sliders with lazy loading in Webflow, you can follow these steps:

  1. Prepare your images: Before adding them to your Webflow project, make sure you have different sized versions of each image. This ensures that the most appropriately sized image is loaded on different devices and screen resolutions.

  2. Use the Webflow Image element: In your Webflow project, add an Image element to your slider. Choose the appropriate layout for your image (e.g., contain, cover, or auto).

  3. Set up the Slick slider: Install the Slick slider plugin using Webflow's custom code feature, or use the Slick Carousel component from Webflow's Asset Marketplace.

  4. Customize the Slick settings: In the settings of the Slick slider, locate the lazyLoad parameter and set it to ondemand. This enables lazy loading of images, which improves performance by only loading images when they're needed.

  5. Add custom code: In the Webflow Designer or Editor, go to the page where you have the Slick slider. Open the custom code settings for that page (in the page settings or site settings).

  6. Add the code: In the Head Code section, add a <style> block with the following CSS code:

.slick-slide img {  width: 100%;  height: auto;}.slick-slide:not(.slick-initialized) img[data-lazy] {  width: 100%;  height: auto;  object-fit: contain;}[data-wf-slick-slider="YOUR_SLIDER_NAME"] img[data-lazy] {  object-fit: contain;}[data-wf-slick-slider="YOUR_SLIDER_NAME"] img[data-lazy].responsive-width {  width: 100%;  height: auto;}
  1. Adjust the code: Replace YOUR_SLIDER_NAME with the actual name of your Slick slider component.

  2. Add the responsive image sizes: Go back to the Designer or Editor and select the Image element within your Slick slider. Add the class responsive-width to the Image element.

  3. Publish your website: After making all the necessary changes, publish your website to see the responsive image sizes in action.

By following these steps, you can ensure that your Slick slider with lazy loading in Webflow displays responsive images with appropriate sizes for different devices and screen resolutions.
