Question

您好，我想制作一个番茄钟。我通过删除边框右边和增加边框左边宽度来创建一个三角形来制作播放按钮。

我的问题是 - 如何应用border-radius？

  <div id="all-buttons" class="buttons">
    <!-- play button -->
    <div id="play" class="play-button"></div>
    <!-- pause button -->
    <div id="pause">
      <div class="line-1"></div>
      <div class="line-2"></div>
    </div>
  <!-- end of play and pause button-->
  </div> 

.play-button {
    z-index: 2;
    width: 48px;
    height: 48px;
    border-style: solid;
    border-width: 24px 0px 24px 48px;
    border-color: white white white #FF8F83;
}

Answer 1

HTML播放按钮：

＆＃13;

.circle_inner{
    position: relative;
    height: 100%;
}
.circle_inner:before{
    content: "";
    display: block;
    width: 0;
    height: 0;
    border-style: solid;
    border-width: 10px 0 10px 20px;
    border-color: transparent transparent transparent #000;
    position: absolute;
    top: 50px;
    left: 50%;
    margin: -10px 0 0 -7px;
}

＆＃13;

        <div class="circle_inner">
            
        </div>

＆＃13;

尝试this（减去）

<div class="control play">
  <span class="left"></span><span class="right"></span>
</div>

.control {
  @color: #ffb160;
  @highlight: darken(@color, 10%);
  @duration: 0.4s;
  @sin:  0.866;
  @size: 112px;

  border-radius: 50%;
  margin: 20px;
  padding: @size*0.25;
  width: @size;
  height: @size;
  font-size: 0;
  white-space: nowrap;
  text-align: center;
  cursor: pointer;

  &, .left, .right, &:before {
    display: inline-block;
    vertical-align: middle;
    transition: border @duration, width @duration, height @duration, margin @duration;
    transition-tiomig-function: cubic-bezier(1, 0, 0, 1);
  }

  &:before {
    content: "";
    height: @size;
  }

  &.pause {
    .left, .right {
      margin: 0;
      border-left: @size*0.33 solid @color;
      border-top: 0 solid transparent;
      border-bottom: 0 solid transparent;
      height: @size*@sin;
    } 

    .left {
      border-right: @size*0.2 solid transparent;
    }
  }

  &.play {
    @border: @size/4;

    .left {
      margin-left: @size/6;
      border-left: @size*@sin/2 solid @color;
      border-top: @border solid transparent;
      border-bottom: @border solid transparent;
      border-right: 0px solid transparent;
      height: @size - 2*@border;
    } 

    .right {
      margin: 0;
      border-left: @size*@sin/2 solid @color;
      border-top: @border solid transparent;
      border-bottom: @border solid transparent;
      height: 0px;
    }
  }

  &:hover {
    border-color: @highlight;

    .left, .right {
      border-left-color: @highlight;
    }
  }
}
