Question

当我调整浏览器大小时，图像会调整大小。这很好，因为这是我想要做的。但是，黑色区域的下半部分不会调整大小。因此在移动浏览器中，图像下方有黑色区域。我想解决它，但我不知道该怎么做。你能给我建议吗？

使用：Bootstrap，jQuery，BxSlider

Answer 1

给予身高：100％;用于图像标记

Answer 2

删除所有父元素的高度

 div#berry {
    /* height: 250px; */
 }

Answer 3

删除身高

.bxslider li {
    height: 250px;
}
div#berry {
    height: 250px;
}

它应该有效

另外你可以使用下面的代码替换你现有的h2.juice代码，这也将删除剩余的黑色空间

h2.juice {
    position: absolute;
    z-index: 10;
    top: 50%;
    margin: 0;
    left: 20%;
}

不要忘记过刷新页面，请参阅图片以供参考here
