如何用一行 CSS 分别实现 10 种现代布局？

前言

更新于 2020/7/12，和 Una Kravets 邮件确认了下，最近她在 web.dev 也发布了新的关于视频里面布局的 blog，有兴趣的可以前去一观 one line layouts

周日在家看 web.dev 的 2020 三天 live，发现不少有意思的东西，其中有一项是关于 CSS 的，主播是 Una Kravets（chrome team 成员）。虽然我已经好几个月没有深入研究 CSS 的东西了，不过以前的底子还在（有兴趣的可以看我一年前发布的关于 CSS 的东西，虽然由于太过底层没啥人愿意看, sad）。

注意：下面大部分代码已经由各大主流最新浏览器实现，切记不要使用在 production 当中

注意：本文所有的代码来自于 Una Kravets。网络较好的，可以看 Una Kravets 的为 web.dev 专门写的网址，里面有所有的demo - 1linelayouts

01. 超级居中

在没有 flex 和 grid 之前，垂直居中一直不能很优雅的实现。而现在，我们可以结合 grid 和 place-items 优雅的同时实现水平居中和垂直居中。

<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent blue"</span> &gt;</span>
  <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box coral"</span> <span class="hljs-attr">contenteditable</span>&gt;</span>
    :)
  <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
<span class="copy-code-btn">复制代码</span>
<span class="hljs-selector-class">.ex1</span> <span class="hljs-selector-class">.parent</span> {
    <span class="hljs-attribute">display</span>: grid;
    <span class="hljs-attribute">place-items</span>: center;
  }
<span class="copy-code-btn">复制代码</span>

02. 可解构的自适应布局(The Deconstructed Pancake)

flex: 0 1 <baseWidth>

这种布局经常出现在电商网站：

  1. 在 viewport 足够的时候，三个 box 固定宽度横放
  2. 在 viewport 不够的时候（比如在 mobile 上面），宽度仍然固定，但是自动解构（原谅我的中文水平），不在同一水平面上
<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent white"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box green"</span>&gt;</span>1<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box green"</span>&gt;</span>2<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box green"</span>&gt;</span>3<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
  <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
<span class="copy-code-btn">复制代码</span>
<span class="hljs-selector-class">.ex2</span> <span class="hljs-selector-class">.parent</span> {
    <span class="hljs-attribute">display</span>: flex;
    <span class="hljs-attribute">flex-wrap</span>: wrap;
    <span class="hljs-attribute">justify-content</span>: center;
  }

  <span class="hljs-selector-class">.ex2</span> <span class="hljs-selector-class">.box</span> {
    <span class="hljs-attribute">flex</span>: <span class="hljs-number">1</span> <span class="hljs-number">1</span> <span class="hljs-number">150px</span>; <span class="hljs-comment">/*  flex-grow: 1 ，表示自动延展到最大宽度 */</span>
    <span class="hljs-attribute">flex</span>: <span class="hljs-number">0</span> <span class="hljs-number">1</span> <span class="hljs-number">150px</span>; <span class="hljs-comment">/*  No stretching: */</span>
    <span class="hljs-attribute">margin</span>: <span class="hljs-number">5px</span>;
  }
<span class="copy-code-btn">复制代码</span>

当我们设置 flex: 1 1 150px; 时候：

03. 经典的 sidebar

grid-template-columns: minmax(<min>, <max>) ...

同样使用 grid layout，可以结合 minmax() 实现弹性的 sidebar（这在你要适应大屏幕的时候很有用）。minmax(<min>, <max>) 就是字面意思。结合 <flex> 单位，非常优雅，避免了数学计算宽度等不灵活的手段（比如我们设置 gap 的时候）。

<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"section yellow"</span> <span class="hljs-attr">contenteditable</span>&gt;</span>
    Min: 150px / Max: 25%
    <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"section purple"</span> <span class="hljs-attr">contenteditable</span>&gt;</span>
      This element takes the second grid position (1fr), meaning
      it takes up the rest of the remaining space.
    <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
  <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
<span class="copy-code-btn">复制代码</span>
<span class="hljs-selector-class">.ex3</span> <span class="hljs-selector-class">.parent</span> {
    <span class="hljs-attribute">display</span>: grid;
    <span class="hljs-attribute">grid-template-columns</span>: <span class="hljs-built_in">minmax</span>(150px, 25%) <span class="hljs-number">1</span>fr;
  }
<span class="copy-code-btn">复制代码</span>

04. 固定的 header 和 footer

grid-template-rows: auto 1fr auto

固定高度的 header 和 footer，占据剩余空间的 body 是经常使用的布局，我们可以利用 grid 和 fr 单位完美实现。

<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">header</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"blue section"</span> <span class="hljs-attr">contenteditable</span>&gt;</span>Header<span class="hljs-tag">&lt;/<span class="hljs-name">header</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">main</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"coral section"</span> <span class="hljs-attr">contenteditable</span>&gt;</span>Main<span class="hljs-tag">&lt;/<span class="hljs-name">main</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">footer</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"purple section"</span> <span class="hljs-attr">contenteditable</span>&gt;</span>Footer Content<span class="hljs-tag">&lt;/<span class="hljs-name">footer</span>&gt;</span>
  <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
<span class="copy-code-btn">复制代码</span>
<span class="hljs-selector-class">.ex4</span> <span class="hljs-selector-class">.parent</span> {
    <span class="hljs-attribute">display</span>: grid;
    <span class="hljs-attribute">grid-template-rows</span>: auto <span class="hljs-number">1</span>fr auto;
  }
<span class="copy-code-btn">复制代码</span>

05. 经典的圣杯布局(classical holy Grail layout)

grid-template: auto 1fr auto / auto 1fr auto

我们可以轻松的使用 Grid 布局来实现圣杯布局，并且是弹性的。

<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">header</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"pink section"</span>&gt;</span>Header<span class="hljs-tag">&lt;/<span class="hljs-name">header</span>&gt;</span>

06. 有意思的叠块

使用 grid-template-columns 和 grid-column 可以实现如下图所示的布局。进一步说明了 repeat 和 fr 的便捷性。

07. RAM 技巧

grid-template-columns: repeat(auto-fit, minmax(<base>, 1fr))

Una Kravets 称之为 repeat, auto, minmax 技巧。这在弹性布局 图片/box 这类非常有用(一行可以排放的卡片数量自动适应)。

<span class="hljs-selector-class">.ex7</span> <span class="hljs-selector-class">.parent</span> {
    <span class="hljs-attribute">display</span>: grid;
    <span class="hljs-attribute">grid-gap</span>: <span class="hljs-number">1rem</span>;
    <span class="hljs-attribute">grid-template-columns</span>: <span class="hljs-built_in">repeat</span>(auto-fit, minmax(150px, 1fr));
  }
<span class="copy-code-btn">复制代码</span>
<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent white"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box pink"</span>&gt;</span>1<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box purple"</span>&gt;</span>2<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box blue"</span>&gt;</span>3<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"box green"</span>&gt;</span>4<span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
  <span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
<span class="copy-code-btn">复制代码</span>

其效果是如果能够满足多个 box 的最小宽度（比如上面的 150px），自动弹性适应放在多行。 举个例子:

  1. 当前宽度是 160px（不考虑 gap），那么上面四个 box 的宽度会自适应为 160px,并且分为 4 行
  2. 当前宽度是 310px （不考虑 gap），上面四个 box 分成两行，两个 box 平分宽度
  3. 当满足一行放下 3 个box 时，第三个 box 自动到第一行
  4. 当满足一行放下 4 个 box 时，第四个 box 自动到第一行

如果我们将 auto-fit 改为 auto-fill:

08. 卡片弹性自适应

justify-content: space-between，结合 grid 和 flex 实现完美的卡片布局。

无论是宽度或高度的收缩还是延展，都可以完美的展现 card 的布局。

09. 使用 clamp 实现 fluid typography

clamp(<min>, <actual>, <max>)

使用最新的 clamp() 方法可以一行实现 fluid typography。提高 UX，非常适合包含阅读内容的 card，因为我们不希望一行字太短或太长。

<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent white"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"card purple"</span>&gt;</span>
      <span class="hljs-tag">&lt;<span class="hljs-name">h1</span>&gt;</span>Title Here<span class="hljs-tag">&lt;/<span class="hljs-name">h1</span>&gt;</span>

<span class="copy-code-btn">复制代码</span>
<span class="hljs-selector-class">.ex9</span> <span class="hljs-selector-class">.parent</span> {
    <span class="hljs-attribute">display</span>: grid;
    <span class="hljs-attribute">place-items</span>: center;
  }

  <span class="hljs-selector-class">.ex9</span> <span class="hljs-selector-class">.card</span> {
    <span class="hljs-attribute">width</span>: <span class="hljs-built_in">clamp</span>(23ch, 50%, 46ch);
    <span class="hljs-attribute">display</span>: flex;
    <span class="hljs-attribute">flex-direction</span>: column;
    <span class="hljs-attribute">padding</span>: <span class="hljs-number">1rem</span>;
  }

  <span class="hljs-selector-class">.ex9</span> <span class="hljs-selector-class">.visual</span> {
      <span class="hljs-attribute">height</span>: <span class="hljs-number">125px</span>;
      <span class="hljs-attribute">width</span>: <span class="hljs-number">100%</span>;
    }
  
<span class="copy-code-btn">复制代码</span>

10. 完美实现比例

aspect-ratio: <width> / <height>

在展现 CMS 或其他设计内容时，我们会期望图片、video、卡片能够按照固定的比例进行布局。而最新的 aspect-ratio 就能优雅的实现该功能(使用 chrome 84+)

<span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"parent white"</span>&gt;</span>
    <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"card blue"</span>&gt;</span>
      <span class="hljs-tag">&lt;<span class="hljs-name">h1</span>&gt;</span>Video Title<span class="hljs-tag">&lt;/<span class="hljs-name">h1</span>&gt;</span>
      <span class="hljs-tag">&lt;<span class="hljs-name">div</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"visual green"</span>&gt;</span><span class="hljs-tag">&lt;/<span class="hljs-name">div</span>&gt;</span>
      <span class="hljs-tag">&lt;<span class="hljs-name">p</span>&gt;</span>Descriptive Text. This demo works in Chromium 84+.<span class="hljs-tag">&lt;/<span class="hljs-name">p</span>&gt;</span>
