如何让span正确环绕图标

Question

我有以下 HTML 代码，用于显示带有计数器徽章的购物车图标。 SVG 图标包装在容器 SPAN 中。但是，正如您在附图中所看到的，由于某种原因，该容器（红色边框）和图标（蓝色边框）之间存在一些未对齐，并且图标溢出到容器之外。

有什么办法可以让容器的边界和图标正确贴合吗？

HTML：

<ul class="site-header-cart">
    <li>
        <a class="cart-contents" href="https://www.example.com/cart/">
            <span class="cart-button">
                <svg class="svg-icon" width="20" height="20" aria-hidden="true" role="img" focusable="false" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg" style="border: 1px solid blue;"><path d="M 7.499889,21 Q 6.7574042,21 6.2286651,20.47125 5.6999261,19.9425 5.6999261,19.2 5.6999261,18.4575 6.2286651,17.92875 6.7574042,17.4 7.499889,17.4 8.2423738,17.4 8.771113,17.92875 9.2998519,18.4575 9.2998519,19.2 9.2998519,19.9425 8.771113,20.47125 8.2423738,21 7.499889,21 Z M 16.499704,21 Q 15.757219,21 15.22848,20.47125 14.699741,19.9425 14.699741,19.2 14.699741,18.4575 15.22848,17.92875 15.757219,17.4 16.499704,17.4 17.242189,17.4 17.770928,17.92875 18.299667,18.4575 18.299667,19.2 18.299667,19.9425 17.770928,20.47125 17.242189,21 16.499704,21 Z M 6.7349048,6.6 8.8948603,11.1 H 15.194731 L 17.66968,6.6 Z M 5.8799223,4.8 H 19.15465 Q 19.672138,4.8 19.942133,5.2612499 20.212128,5.7225 19.964633,6.1949999 L 16.769698,11.955 Q 16.522203,12.405 16.105962,12.6525 15.689721,12.9 15.194731,12.9 H 8.4898688 L 7.499889,14.7 H 18.299667 V 16.5 H 7.499889 Q 6.4874098,16.5 5.9699205,15.611249 5.4524311,14.7225 5.9249213,13.845 L 7.1398964,11.64 3.899963,4.8 H 2.1 V 3 H 5.0249398 Z M 8.8948603,11.1 H 15.194731 Z"></path>

            </span>
        </a>
    </li>
</ul>

CSS：

.site-header-cart {
  position: relative;
  margin: 0;
  padding: 0;
  list-style: none;
}
.site-header-cart .cart-contents {
  display: inline-block;
  background-color: transparent;
  height: auto;
  width: auto;
  padding: 10px 0;
  color: #222;
  font-size: 0.875rem;
  text-decoration: none;
  border: 1px solid lightgray;
}
.site-header-cart .cart-contents .cart-button {
  position: relative;
  border: 1px solid red;
}
.site-header-cart .cart-contents .cart-button svg {
  display: inline-block;
  max-width: 100%;
  fill: currentColor;
  border: 1px solid blue;
}
.site-header-cart .cart-contents .cart-button .cart-badge {
  position: absolute;
  top: -5px;
  right: -5px;
  width: 15px;
  color: #fff;
  background-color: #999;
  border-radius: 100%;
  font-size: 0.563rem;
  line-height: 15px;
  text-align: center;
}

结果：

Answer 1

将

display: flex

与

align-items: center

和

justify-content: center

添加到

.site-header-cart .cart-contents .cart-button

选择器将在其容器内正确对齐 SVG 图标。

.site-header-cart {
  position: relative;
  margin: 0;
  padding: 0;
  list-style: none;
}
.site-header-cart .cart-contents {
  display: inline-block;
  background-color: transparent;
  height: auto;
  width: auto;
  padding: 10px 0;
  color: #222;
  font-size: 0.875rem;
  text-decoration: none;
  border: 1px solid lightgray;
}
.site-header-cart .cart-contents .cart-button {
  position: relative;
  display: flex; /* Added this */
  align-items: center; /* Added this */
  justify-content: center; /* Added this */
  border: 1px solid red;
}
.site-header-cart .cart-contents .cart-button svg {
  display: inline-block;
  max-width: 100%;
  fill: currentColor;
  border: 1px solid blue;
}
.site-header-cart .cart-contents .cart-button .cart-badge {
  position: absolute;
  top: -5px;
  right: -5px;
  width: 15px;
  color: #fff;
  background-color: #999;
  border-radius: 100%;
  font-size: 0.563rem;
  line-height: 15px;
  text-align: center;
}
