html - 如何在 jquery LightSlider 中使用居中图像设置固定高度？

Question

我有一个灯 slider ，上面有不同高度的不同图像。如果我将 isAdaptiveHeight 设置为 true，那么它会根据图像自动调整高度，但这对我来说不太好。

我想设置图像的固定高度，如果任何图像很小，那么我想将该图像设置在固定高度的中心。这是我的 fiddler :http://jsfiddle.net/mbjvc5u8/1/ .

第一张图片小，其他图片大，所以我不想调整 UI。我想要带有居中图像的固定高度的光 slider 。我试过了，但我做不到。

Answer 1

我希望这对你有用:

$('#lightSlider').lightSlider({
  gallery: true,
  item: 1,
  loop: true,
  slideMargin: 0,
  thumbItem: 9,
  onSliderLoad: function() {


    $("img").addClass("preferredHeight");



  }


});

.demo {
  width: 420px;
}

ul {
  list-style: none outside none;
  padding-left: 0;
  margin-bottom: 0;
}

li {
  display: block;
  float: left;
  margin-right: 6px;
  cursor: pointer;
}

img {
  display: block;
  height: auto;
  max-width: 100%;
}

.preferredHeight {
  max-height: 127px;
  position: relative;
  left: 50%;
  transform: translate(-50%);
}
