How can I create an image that spans the entire width of the screen, Swiper?

var swiper = new Swiper('.swiper-container', {
      pagination: {
        el: '.swiper-pagination',
      },
  });
html,
    body {
      position: relative;
      height: 100%;
    }

    body {
      background: #eee;
      font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
      font-size: 14px;
      color: #000;
      margin: 0;
      padding: 0;
    }

    .swiper-container {
      width: 100%;
      height: 500px;
    }

    .swiper-slide {
      text-align: center;
      font-size: 18px;
      background: #fff;

      /* Center slide text vertically */
      display: -webkit-box;
      display: -ms-flexbox;
      display: -webkit-flex;
      display: flex;

I am utilizing the swiper library to craft a mobile image slider on my application. You can view a simple demo from . The first slide's image does not take up the entire available width. I have tried changing the width to 100vw but it is not helping. Is there a single line of code that can achieve this? Your assistance in resolving this issue would be greatly appreciated. Thank you in advance.

Answer №1

Adjust the image width to 100% for it to occupy the entire width of its parent element. Maintain the image's aspect ratio by setting the height to auto and utilize the object-fit property to resize the image accordingly:

.swiper-container .swiper-zoom-container>img {
    width: 100%;
    height: auto;
    object-fit: cover;
    object-position: center;
}

Additionally, you can use the object-position property to specify the alignment of your image.

var swiper = new Swiper('.swiper-container', {
  pagination: {
    el: '.swiper-pagination',
  },
});
html,
body {
  position: relative;
  height: 100%;
}

body {
  background: #eee;
  font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
  font-size: 14px;
  color: #000;
  margin: 0;
  padding: 0;
}

.swiper-container {
  width: 100%;
  height: 500px;
}

.swiper-slide {
  text-align: center;
  font-size: 18px;
  background: #fff;
  /* Center slide text vertically */
  display: -webkit-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-box-pack: center;
  -ms-flex-pack: center;
  -webkit-justify-content: center;
  justify-content: center;
  -webkit-box-align: center;
  -ms-flex-align: center;
  -webkit-align-items: center;
  align-items: center;
}

.swiper-container .swiper-zoom-container>img {
    width: 100%;
    height: auto;
    object-fit: cover;
    object-position: center;
}

Answer №2

Make sure to include this code in your CSS file for the swiper to function correctly. Adding !important is necessary to override any default properties that may interfere with your custom styles.

.swiper-lazy-loaded {
     object-fit: cover !important;
     width: 100% !important;
     max-width: none !important;
}


var swiper = new Swiper('.swiper-container', {
      pagination: {
        el: '.swiper-pagination',
      },
  });
html,
    body {
      position: relative;
      height: 100%;
    }

    body {
      background: #eee;
      font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
      font-size: 14px;
      color: #000;
      margin: 0;
      padding: 0;
    }

    .swiper-container {
      width: 100%;
      height: 500px;
    }

    .swiper-slide {
      text-align: center;
      font-size: 18px;
      background: #fff;

      /* Center slide text vertically */
      display: -webkit-box;
      display: -ms-flexbox;
      display: -webkit-flex;
      display: flex;
      -webkit-box-pack: center;
      -ms-flex-pack: center;
      -webkit-justify-content: center;
      justify-content: center;
      -webkit-box-align: center;
      -ms-flex-align: center;
      -webkit-align-items: center;
      align-items: center;
    }
    .swiper-lazy-loaded {
     object-fit: cover !important;
     width: 100% !important;
     max-width: none !important;
}
