Question

在“Codepen.io”上，我找到了一个很好的圆形菜单 CSS，我想使用它。 (https://codepen.io/oliver_merz/pen/zqXZQG)。但是正如您所看到的，标签(按钮)是空的。里面应该有图片。我用随机图像 ( https://image.flaticon.com/icons/svg/771/771605.svg ) 对此进行了测试。不幸的是，什么都没有出现..

它是关于下面的CSS代码:

.cssplay-menu .segment label {
  display: block;
  position: absolute;
  left: 50%;
  top: 50%;
  width: 50%;
  height: 50%;
  background: #008080;
  border: 1px solid #fff;
  cursor: pointer;
  transform-origin: left top;
  transition: 0.25s cubic-bezier(0, 0, 1, 1);
  transition: 0.25s ease;
}

Answer 1

您需要调整一些 CSS 以使它们可见，因为实际上它们是隐藏的:

.cssplay-menu .segment label span {
  display: block;
  position: absolute;
  left: 0;
  top: 0;
  right: 50%; /*changed*/
  bottom: 10%; /*changed*/
  margin: auto;
  width: 35px;
  height: 35px;
  background-position: center center;
  background-repeat: no-repeat;
}
