如何将焦点添加到没有 href 的锚点？

Question

我有一个大型站点，并且有数百个锚标记没有附加href 属性。与其冒险进行搜索/替换并添加href="#"，我更愿意使用CSS 来定位它们。我正在尝试将焦点状态应用于这些，但事实证明这很困难。我正在使用以下 :not([href]) 来定位那些非 href 链接，但我似乎无法专注于它。

/* Duru Sans */
@import url("https://fonts.googleapis.com/css2?family=Duru+Sans&display=swap");
/*resets*/
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

html,
body {
  font-family: "Duru Sans", sans-serif;
  font-size: 16px;
}

.container {
  display: flex;
  flex-direction: column;
  justify-content: space-around;
  align-items: center;
  height: 60vh;
}

a {
  text-decoration: none;
}
a.custom-bttn-anim:not([href]), a.custom-bttn-anim {
  align-items: center;
  border: 0;
  border-radius: 4px;
  box-shadow: 0px 12px 30px rgba(0, 0, 0, 0.12);
  cursor: pointer;
  display: inline-flex;
  font-size: 1.062rem;
  font-weight: 700;
  justify-content: center;
  min-width: 185px;
  outline: 0;
  padding: 1.25rem 0;
  position: relative;
  text-transform: none;
  transition: all 0.2s ease;
}
a.custom-bttn-anim:not([href]):hover, a.custom-bttn-anim:hover {
  box-shadow: 0px 8px 12px rgba(0, 0, 0, 0.08);
}
a.custom-bttn-anim:not([href]):before, a.custom-bttn-anim:before {
  content: "";
  position: absolute;
  border: solid 0px #005fec;
  top: 0px;
  bottom: 0px;
  left: 0px;
  right: 0px;
  opacity: 0;
  transition: all 0.2s ease;
  border-radius: 4px;
  filter: blur(4px);
}
a.custom-bttn-anim:not([href]):focus-visible:before, a.custom-bttn-anim:focus-visible:before {
  content: "";

  bottom: -8px;
  left: -8px;
  right: -8px;

a.custom-blue-bttn {
  background: #005fec;
  color: white;
}
a.custom-bttn-anim .bttn-txt {
  color: inherit;
  font-weight: inherit;
  display: inline-block;
  transform: translateX(0.625rem);
  transition: transform 0.2s;
}
a.custom-bttn-anim .learn-more-arrow {
  height: 0.75rem;
  opacity: 0;
  transition: opacity 0.2s, transform 0.2s;
}
a.custom-bttn-anim:hover .bttn-txt {
  transform: translate(0px);
  transition: transform 0.2s;
  margin-right: 0.3rem;
}
a.custom-bttn-anim:hover .learn-more-arrow {
  opacity: 1;
  transition: opacity 0.2s, transform 0.2s;
}

<div class="container">

没有href 属性的锚元素默认是不可聚焦的。

您可以使用 tabindex 属性使它们成为焦点，尽管我不确定这是否比添加 href="#" 更适合您。

例子：

<a tabindex="0">
    <!-- other stuff -->
</a>

您甚至可以使用一些 JavaScript 来动态添加属性：

document.querySelectorAll("a:not(a[href])").forEach(element => {
    element.setAttribute("tabindex", "0")
});

如果空锚标签不导航到 URI，那么这种配置可能会让使用辅助技术的人感到困惑，带有附加事件处理程序的按钮可能是更合适的选择。
