变换旋转菜单项圆形菜单

Question

我修改了一个发现on this pen的圆形菜单 但是我无法在主圆上旋转菜单项。默认情况下，这只笔的按钮的底部垂直于它的相对位置，但是由于我用字体图标更改了它们，所以它们看起来上下颠倒或弯曲。

我是CSS菜鸟，所以需要一些帮助，已经工作了几个小时！

我尝试了一些类似的事情：

menu li::after{
  transform: rotate(0deg);
  -webkit-transform: rotate(0deg);
}

或类似的

menu li li:nth-of-type(1) {
  -webkit-transform: rotate(180deg) translate(0, 0);
  transform: rotate(180deg) translate(0, 0);
}

它们似乎都不起作用。目前，我的组件如下所示：

这是我完整的CSS和HTML ...

menu {
  transition: all 0.25s ease-in-out;
  transition-delay: 0.75s;
  -webkit-transform: rotate(0deg);
  transform: rotate(0deg);
  background-color: #2e7bbd;
  margin: -45px 0 0 -45px;
  position: fixed;
  width: 90px;
  height: 90px;
  border-radius: 50%;
  cursor: pointer;
  right: 2%;
  bottom: 2%;
  z-index: 99999;
}

menu:before, menu:after {
  content: "";
  z-index: 2;
  position: fixed;
  width: 3px;
  height: 22.5px;
  cursor: pointer;
  background-color: #fbfdff;
  top: 50%;
  left: 50%;
}

menu:before {
  -webkit-transform: translate(-50%, -50%) rotate(-90deg);
  transform: translate(-50%, -50%) rotate(-90deg);
}
menu:after {
  -webkit-transform: translate(-50%, -50%) rotate(0deg);
  transform: translate(-50%, -50%) rotate(0deg);
}

menu li {
  transition: all 0.25s ease-in-out;
  transition-delay: 0.75s;
  width: 59.4px;
  height: 59.4px;
  margin: -29.7px 0 0 -29.7px;
  opacity: 0;
  text-align: center;
  font-size: 18px;
  font-family: Helvetica, sans-serif;
  font-weight: 100;
  line-height: 59.4px;
  color: #fbfdff;
  border-radius: 50%;
  background-color: #428dce;
  list-style-type: none;
  position: fixed;
  z-index: 100;
  left: 50%;
  top: 50%;
}

menu li::after{
  transform: rotate(0deg);
  -webkit-transform: rotate(0deg);
}

menu li li:nth-of-type(1) {
  -webkit-transform: rotate(180deg) translate(0, 0);
  transform: rotate(180deg) translate(0, 0);
  animation-name: crazy;
  animation-duration: 2s;
  animation-delay: 1s;
  animation-iteration-count: infinite;
}

menu li li:nth-of-type(2) {
  -webkit-transform: rotate(0deg) translate(0, 0);
  transform: rotate(0deg) translate(0, 0);
}

menu li li:nth-of-type(3) {
  -webkit-transform: rotate(0deg) translate(0, 0);
  transform: rotate(0deg) translate(0, 0);
}

menu:hover {
  -webkit-transform: rotate(-180deg);
  transform: rotate(-180deg);
  transition-delay: 0s;
}

menu:hover li {
  transition-delay: 0.1s;
  opacity: 1;
}

menu:hover li:nth-of-type(1) {
  -webkit-transform: rotate(359deg) translate(0, 90px);
  transform: rotate(359deg) translate(0, 90px);
}

menu:hover li:nth-of-type(2) {
  -webkit-transform: rotate(310deg) translate(0, 90px);
  transform: rotate(310deg) translate(0, 90px);
}

menu:hover li:nth-of-type(3) {
  -webkit-transform: rotate(260deg) translate(0, 90px);
  transform: rotate(260deg) translate(0, 90px);
}

<!--<menu>
    <li><i className="fas fa-bell"></i></li>
    <li><i className="fas fa-cog"></i></li>
    <li><i className="fas fa-terminal"></i></li>
</menu>-->

<menu>
    <li>1</li>
    <li>2</li>
    <li>3</li>
</menu>

编辑：我不知道为什么该按钮在代码段中看起来像一个椭圆，但是为了这个参数，让我们忽略它。在我的应用上看起来不错：）

这已解决您的轮换问题。请检查我的代码。

我在每个li之后添加了一个，然后在其中设置了旋转，这是我添加的代码。

menu li i{
  content: "1";
  display: flex !important;
  align-items: center;
  justify-content: center;
  transform-origin: center;
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  border-radius: 100%;
}

menu li:nth-of-type(1) i {
  transform: rotate(180deg);
}

menu li:nth-of-type(2) i {
  transform: rotate(230deg);
}

menu li:nth-of-type(3) i {
  transform: rotate(280deg);
}

这是您的完整代码。

  transform: rotate(310deg) translate(0, 90px);
}

}

menu li:nth-of-type(2) i {
  transform: rotate(230deg);
}

menu li:nth-of-type(3) i {
  transform: rotate(280deg);
}

这是HTML

    <menu>
    <li><i class="fas fa-bell"></i></li>
    <li><i class="fas fa-cog"></i></li>
    <li><i class="fas fa-terminal"></i></li>
</menu>

  transform: rotate(260deg) translate(0, 90px);
}
li a {
  transform :rotate(180deg);
  display:block;
}

<menu>
  <li><a>1</a></li>
    <li><a>2</a></li>
    <li><a>3</a></li>
</menu>

像我一样将列表内容包装在block元素或inline元素中！并将这个元素旋转180度！

Answer 3

这将解决您的轮换问题。

li a {
  transform :rotate(180deg);
}

此外，如果您需要对+图标进行适当的圆形设计，则需要为CSS中的width类修复height和.menu，如下所示：

  width: 30px;
  height: 70px;
