围绕内联编号圈出

Question

我试图在这样的数字周围创建一个圆形边框：

但到目前为止，我所有的尝试都产生了一个椭圆形：

Codepen to see it live 到目前为止的SCSS代码

$browser-context: 16;

@function em($pixels, $context: $browser-context) {
    @return #{$pixels/$context}em;
}

body {
    line-height: 1.6;
    display: flex;
    flex-direction: column;
    min-height: 100vh;
    font-family: 'PT Sans', sans-serif;
    background: #e5dde1;
}

ul {
    margin: 0;
    padding: 0;
    list-style: none;
}

.header-nav {
    background-color: #ff4c61;
    color: white;
    font-family: 'Oswald', sans-serif;
}

.category-nav ul {
  background-color: #212d5b;
  color: #ff4c61;
  display: flex;
  justify-content: space-evenly;
}

.category-nav a {
  font-size: em(34);  
  text-decoration: none;
}

.category-nav .circled {
      border-radius: 50%;
      width: em(12);
      height: em(12);
      padding: em(4);
      border: em(1) solid #ff4c61;
}

HTML：

<header class="header-nav">
  <h1> APP</h1>
</header>
<nav class="category-nav">
  <ul>
    <li><a href="#">A</a></li>
    <li><a href="#">B</a></li>
    <li><a href="#">C <span class="circled">3</span></a></li>
  </ul>
</nav>

到目前为止，我一直在尝试不同的解决方案，我认为问题主要来自于数字的容器是内联元素（span）的事实。每当我将类.circled转换为div而不是将显示设置为阻塞时，我会得到一个完美的圆圈但是数字被推出并且它会破坏弹性布局。我想知道是否有办法让圆圈与跨度一起工作？

Answer 1

对于colors.html课程，您需要添加以下样式：

.circled

Answer 2

你可以把它变成一个内联块。将此添加到您的示例中对我有用：

  display: inline-block;
  line-height: em(12);
  text-align: center;
