图像旋转木马消失的箭头

时间：2017-04-18 18:44:45

标签： html css

我在下面的代码中使用了html和css的图片轮播。我怎样才能这样做，只有当你的鼠标悬停在旋转木马上时才会出现左右箭头，当它没有时，箭头会消失。什么都有帮助，谢谢。

答案 1 :(得分：1)

使箭头不透明：0;然后悬停，不透明度：1; 

<div class="thing">
  <div class="arrow">Arrow</div>
</div>

... 

.thing {
  border: 1px solid red;
}

.thing .arrow {
  opacity: 0;
  transition: .3s;
}

.thing:hover .arrow {
  opacity: 1;
}

尝试向后阅读CSS选择器...... “任何箭头 - 在一个悬停的'东西'里面，做这个......”
