如何在CSS / html中创建垂直标尺？

Question

我想在css和html中创建一个垂直标尺。也许这张照片显示了我的目的。创建这个垂直标尺？

我的代码是：

<div>
 <li class='ruler'>0</li>
 <li class='ruler'>5</li>
 <li class='ruler'>10</li>
 <li class='ruler'>15</li>
 <li class='ruler'>20</li>
 </div>

.ruler {
 background: #ffffff;
 box-shadow: 0 -1px 1em hsl(60, 60%, 84%) inset;
 border-radius: 2px;
 border-left: 6px solid #000;
 border-bottom: 1px solid #CCCCCC;
 color: #000000;
 margin: 0;
 height: 80px;
 list-style: none;
 text-align: right;
 width: 60px;
 } 

Answer 1

这就是我（可能）尝试实现这个想法的方式：

ol,
li {
  /* removing the default list counters/markers: */
  list-style-type: none;
}
ol {
  /* resetting the counter so every <ol>
     has an independent count: */
  counter-reset: marker;
}
li {
  /* 'real world' measurements are perhaps not
     entirely faithful on screen: */
  height: 1cm;
  border-top: 1px solid #000;
  /* including the border in the height of the element: */
  box-sizing: border-box;
  width: 2.5em;
  /* incrementing the counter: */
  counter-increment: marker;
  /* to position the counter relative
     to the <li>: */
  position: relative;
  border-left: 2px solid #000;
}
li:first-child,
li:nth-child(5n) {
  /* longer mark for the first and
     every fifth marker: */
  width: 5em;
}
/* preventing a 'tail' on the <ol> from the
   height of the last <li> (the counter is
   displayed at the top, not the bottom): */
li:last-child {
  height: 0;
}
li:first-child::after,
li:nth-child(5n)::after {
  /* positioning the pseudo-element that
     contains the counter: */
  position: absolute;
  /* vertically-centering it alongside the
     top border: */
  top: -0.5em;
  /* moving it the full width of the element,
     outside of the right side of the element: */
  left: 100%;
  height: 1em;
  line-height: 1em;
  width: 2em;
  text-align: center;
  /* specifying the counter to use: */
  content: counter(marker);
}

<ol id="rule">
  <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>
</ol>
