Customizing Swiper slider to display optimized images based on screen size for enhanced user experience

I am currently working on an ionic app that utilizes the ion-slides directive with a swiper slider to create an image slider. Here is a snippet of how it appears in the view:

<ion-slides ng-if="slider.length > 0 && article.external_media.length < 1" class="slides">
  <ion-slide-page ng-repeat="item in slider">
    <img ng-if="item.image" ng-src="{{ fileServer }}/imagecache/cover/{{ item.image }}" class="cover">
    </ion-slide-page>
</ion-slides>

In addition, this is the corresponding CSS styling for the slider:

.slider {    
  &:after {
    content: "";
    display: block;
    position: absolute;
    width: 200%;
    height: 100%;
    box-shadow: 0px 1.5rem 4.8rem 3rem rgba(0, 0, 0, 0.4) inset;
    bottom: 5px;
    left: -50%;
  }
}

.cover {
  width:100%;
  position: relative;

  &:after {
    content: "";
    display: block;
    position: absolute;
    width: 200%;
    height: 100%;
    box-shadow: 0px -5rem 4.8rem 3rem rgba(0, 0, 0, 0.4) inset;
    bottom: 5px;
    left: -50%;
  }
}

.slides {
  height: 325px;
}

The issue arises when I either do not assign a height to the slides class or set it to 100% or auto. This results in the images not being visible due to the unset height. On the other hand, if I specify a fixed height for the slides class, the images do not resize correctly and end up stretching horizontally on larger screens. How can I address this problem?

Answer №1

By default, Swiper sets the position of swiper-wrapper to absolute. I made a change to set it to relative, allowing me to then adjust the height of the slides to auto. This is the solution that ultimately resolved my issue:

.slides {
  height: auto;
}

.swiper-wrapper {
  position: relative;
}
