在弹性框中左对齐,居中和向右对齐元素

Question

我正在尝试使用flexbox创建这个顶部标题.

基本上我想将<div class="header-title">(机构机构1)与你看到的其他3个元素联系起来.(Institutioner,Ledere和Log ud)就像你在图像上看到的那样.

.nav {
    background: #e1e1e1;
}
ol, ul {
    list-style: none;
    display: flex;
    flex-direction: row;
    align-items: center;
    justify-content: flex-start;
}
.header-title {
  justify-content: center;
    align-self: center;
    display: flex;
}
.nav ul li.logout {
      margin-left: auto;
}
.nav ul li a {
    text-decoration: none;
    padding: 0px 20px;
    font-weight: 600;
}

<div class="nav mobilenav">
  <div class="header-title">
    Institution institution 1
  </div>
  <ul>
    <li><a href="/institutions/">Institutioner</a></li>
    <li>
      <a href="/leaders/">Ledere</a>
    </li>
    <li class="logout">
      <a class="button-dark" href="/user/logout">Log ud</a>
    </li>
  </ul>
</div>

Answer 1

使用嵌套的flex容器和flex-grow: 1.

这允许您在导航栏上创建三个等宽部分.

然后每个部分成为(嵌套的)flex容器,允许您使用flex属性垂直和水平对齐链接.

现在左右项目固定到容器的边缘,中间项目完全居中(即使左右项目的宽度不同).

.nav {
  display: flex;
  height: 50px;      /* optional; just for demo */
  background: white;
}

.links {
  flex: 1;          /* shorthand for: flex-grow: 1, flex-shrink: 1, flex-basis: 0 */
  display: flex;
  justify-content: flex-start;
  align-items: center;
  border: 1px dashed red;
}

.header-title {
  flex: 1;
  display: flex;
  justify-content: center;
  align-items: center;
  border: 1px dashed red;
}

.logout {
  flex: 1;
  display: flex;
  justify-content: flex-end;
  align-items: center;
  border: 1px dashed red;
}

.links a {
  margin: 0 5px;
  text-decoration: none;
}

<div class="nav mobilenav">

  <div class="links">
    <a href="/institutions/">Institutioner</a>
    <a href="/leaders/">Ledere</a>
  </div>

  <div class="header-title">Institution institution 1</div>

  <div class="logout"><a class="button-dark" href="/user/logout">Log ud</a></div>

</div>

justify-content: space-between;像这样使用：

.container {
  display: flex;
  justify-content: space-between;
}

<div class="container">
  <div>A</div>
  <div>B</div>
  <div>C</div>
</div>
