html - float : left and float: right divs(block) doesn't fit on one line

Question

我想创建嵌套菜单。一些菜单项有快捷键，我尝试将它们放在同一行但与右侧对齐。 我尝试为此使用 float 左/右，但我在放置快捷方式时遇到问题，他们转移到下一行。我该如何解决？

你可以在这里看到代码:

.menu-item-container {}

.vert-menu {
  position: absolute;
  min-width: 180px;
  border: #aaa 1px solid;
  background: white;
}

.menu-item-vert {
  float: none;
}

.menu-item {
  font: 13px Arial, sans-serif;
  height:13px;
  color: black;
  padding: 3px 7px 5px 7px;
  white-space: nowrap;
  position: relative;
  background: white;
}

.menu-item-shortcut {
  float: right;
  padding: 0px 0px 0px 24px;
  position: relative;
  color: #777;
  left: auto;
  right: 5px;
  direction: ltr;
  text-align: right;
}

.menu-item-label {
  float:left;
  position: relative;
}

<div class="menu-item-container vert-menu" style="top: 22px; display: inline;">
  <div class="menu-item menu-item-vert">
    <span class="menu-item-label">New...</span>
    <span class="menu-item-shortcut">Ctr+N</span>
  </div>
  <div class="menu-item menu-item-vert">
    <div class="menu-item-container vert-menu" style="top: 0px; display: inline; left: 180px;">
      <div class="menu-item menu-item-vert">
        <span class="menu-item-label">File</span>
        <span class="menu-item-shortcut">Alt+ F</span>
      </div>
      <div class="menu-item menu-item-vert">
        <span class="menu-item-label">Long text that screws up the shortcut</span>
        <span class="menu-item-shortcut">Shift+Del</span>
      </div>
    </div>
    <span class="menu-item-label">Add</span>
    <span class="menu-item-shortcut">▶</span>
  </div>
</div>

Answer 1

您可以使用 flexbox 而不是 floating ，如下面的代码:

1. 将 display:flex 添加到父级。
2. 将 margin-left: auto 添加到 .menu-item-shortcut
3. 从子项中删除 float 属性。

.menu-item-container {}

.vert-menu {
  position: absolute;
  min-width: 180px;
  border: #aaa 1px solid;
  background: white;
}

.menu-item-vert {
  float: none;
  display:flex;
}

.menu-item {
  font: 13px Arial, sans-serif;
  height:13px;
  color: black;
  padding: 3px 7px 5px 7px;
  white-space: nowrap;
  position: relative;
  background: white;
}

.menu-item-shortcut {
  /*float: right;*/
  padding: 0px 0px 0px 24px;
  position: relative;
  color: #777;
  left: auto;
  right: 5px;
  direction: ltr;
  text-align: right;
  margin-left: auto;
}

.menu-item-label {
  /*float:left;*/
  position: relative;
}

<div class="menu-item-container vert-menu" style="top: 22px; display: inline;">
  <div class="menu-item menu-item-vert">
    <span class="menu-item-label">New...</span>
    <span class="menu-item-shortcut">Ctr+N</span>
  </div>
  <div class="menu-item menu-item-vert">
    <div class="menu-item-container vert-menu" style="top: 0px; display: inline; left: 180px;">
      <div class="menu-item menu-item-vert">
        <span class="menu-item-label">File</span>
        <span class="menu-item-shortcut">Alt+ F</span>
      </div>
      <div class="menu-item menu-item-vert">
        <span class="menu-item-label">Long text that screws up the shortcut</span>
        <span class="menu-item-shortcut">Shift+Del</span>
      </div>
    </div>
    <span class="menu-item-label">Add</span>
    <span class="menu-item-shortcut">▶</span>
  </div>
</div>
