html - Focus-Within 适用于 chrome 但不适用于 Firefox

Question

我有一个小的焦点选择器，用于每个页面的表单上的单选按钮，每个页面都有不同的颜色，具体取决于页面，它在 chrome 中运行良好，但在 Firefox 中没有。

#wedo-contact .frm_radio:focus-within{
    background-color:#D81B2D!important;
}


#wedo-contact .frm_radio:-moz-focus-inner{
    background-color:#D81B2D!important;
    outline:none!important;
}

它似乎与 Firefox Mac (Safari) 上的行为和无线电输入焦点有关：https ://bugzilla.mozilla.org/show_bug.cgi?id=756028

Roman Komarov 找到的解决方案是使用 tabindex：https ://www.kizu.ru/keyboard-only-focus/#x

<div class="frm_radio" id="frm_radio_18-0" tabindex="0">
  <label for="field_yhi3q-0" tabindex="-1">
    <input type="radio" name="item_meta[18]" id="field_yhi3q-0" value="WEB DESIGN &amp; DEVELOPMENT" data-invmsg="I would like to talk to you about is invalid" />
    WEB DESIGN &amp; DEVELOPMENT
  </label>
</div>
