使用Tailwind CSS居中文本并将图标放在右侧

Question

我试着用Tailwind CSS建立一个侧边栏菜单。但是我不能像LI-tag的文本一样使图标居中。

    <ul id="sidemenu" class="text-center border-b-2 border-gray-200">
      <li class="border-t-2 border-gray-200">
        <div href="#" class="block cursor-pointer block py-3 relative">
          <span class="">Title 1</span>
          <svg xmlns="http://www.w3.org/2000/svg" class="h-4 w-4 absolute right-1 top-1/2" fill="none" viewBox="0 0 24 24" stroke="currentColor">
            <path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M19 9l-7 7-7-7" />
          </svg>
        </div>
        <ul class="bg-gray-50 border-t-2 border-gray-100">
          <li class="py-2">Sub-Item-1</li>
          <li class="py-2">Sub-Item-2</li>
          <li class="py-2">Sub-Item-3</li>
        </ul>
      </li>
      <li class="border-t-2 border-gray-200">
        <span class=" block py-3 cursor-pointer">Title 2</span>
      </li>
      <li class="border-t-2 border-gray-200">
        <span class=" block py-3 cursor-pointer">Title 3</span>
      </li>
    </ul>

下面是它现在看起来的一个例子：https://jsfiddle.net/j6y3sznq/

Answer 1

类.top-1\/2缺少transform属性，请考虑添加transform: translateY(-50%)以使其居中对齐。

​

.top-1\/2 {
  transform: translateY(-50%);
}

解决方案二:顺风类名。只需将transform -translate-y-2/4添加到svg元素即可。
