Question

平我可能会困，或者有些东西真的缺失了，我没有得到它。做一个教程（时钟），全部编码，不复制粘贴，第二个句柄与原始句柄位于不同的位置。检查，重新检查，找不到任何可以改变它的东西。如果我只是复制粘贴，实际代码就可以工作。

我的代码：

    html{
    background: #018DED url(http://unsplash.it/1500/1000?image=881&blur=50);
    background-size: cover;
    font-family: 'helvetica neue';
    text-align: center;
    font-size: 10px;
}

body{
     margin: 0;
     font-size: 2rem; /*ver a diferença que faz a seguir com o html*/
     display: flex;
     flex:1;
     min-height: 100vh;
     align-items: center;
}

.clock{
    width:30rem;
    height: 30rem;
    border:20px solid white;
    border-radius: 50%;
    margin: 50px auto;  /*centra*/
    position: relative;
    padding: 2rem;
    box-shadow: 
      0 0 0 4px rgba(0,0,0,0.1),
      inset 0 0 0 3px #EFEFEF,
      inset 0 0 10px black,
      0 0 10px rgba(0,0,0,0.2);
}

.clock-face {
    position:relative;
    width: 100%;
    height: 100%
    transform: translateY(-3px);  /* account for the height of the clock hands */
}

.hand {
    width:50%;
    height:6px;
    background: yellow;
    position: absolute;
    top:50%;
}

你丢失了分号。

这里：

.clock-face {
    position:relative;
    width: 100%;
    height: 100% // Missing semicolon here
    transform: translateY(-3px);  /* account for the height of the clock hands */
}

相同的代码，不同的结果css？
