写一下思路，先定义一个钟表的大小位置，用absolute,从1点到12点用ul,li。每个li可以用nth-child(对应第几个)来控制位置，角度用transform，然后分钟的刻度也是照样子分别控制位置，要用48个li，这个就要慢慢算了。
<div id="watch"> <ul class="minute-marks"> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> <li></li><li></li><li></li><li></li><li></li><li></li> </ul> <ul class="digits"> <li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li> <li>7</li><li>8</li><li>9</li><li>10</li><li>11</li><li>12</li> </ul></div>
