html - PrismJs 不会溢出 CSS 网格

Question

我有一个页面布局，其中包含 flex 内容 div 和右侧固定宽度的列。为此，我有以下基本结构:

<div class="grid">
  <div class="content">
    Content here
  </div>
  <div class="column">
    Fixed right column
  </div>
</div>

还有 CSS:

.grid {
    display: grid;
    grid-gap: 10px;
    grid-template-columns: auto 280px;
    width: 500px;
}

.content {
  background: tomato;
}

.column {
  background: deepskyblue;
}

我希望 auto 内容填满总空间减去固定列宽。确实会发生这种情况，除非作为棱镜标签的 div 的内容超出了该宽度。它不是在 PrismJs div 上生成水平滚动条，而是简单地溢出内容 div 并将列进一步向右推。

关于如何让滚动条出现在 div 上而不是插入列有什么想法吗？

请注意，如果我为内容宽度设置一个固定值，它会按预期工作。

举个例子:

.grid {
    display: grid;
    grid-gap: 10px;
    grid-template-columns: auto 280px;
    width: 500px;
}

.content {
  background: tomato;
}

.column {
  background: deepskyblue;
}

<div class="grid">
  <div class="content">
    <pre><code class="language-javascript">@Component({
        selector: "main",
        directives: [],
        template: `
            &lt;button
                (tap) = "onTapMe()"
                text = "tap me" /&gt;
        `
    })
    class MainPage {
        onTapMe() {
            alert("Hello from Angular 2");
        }
        // long coment pushing the right column further right !!!
    }
    </code></pre>
  </div>
  <div class="column">
  
  </div>
</div>

默认情况下网格元素有min-width: auto和min-height: auto(就像flex元素).所以你可以设置 min-width: 0 并添加 oveflow: auto 来修复这个 - 请看下面的演示:

.grid {
    display: grid;
    grid-gap: 10px;
    grid-template-columns: auto 280px;
    width: 500px;
}

.content {
  background: tomato;
  min-width: 0; /* added */
  overflow: auto; /* added */
}

.column {
  background: deepskyblue;
}

<div class="grid">
  <div class="content">
    <pre><code class="language-javascript">@Component({
        selector: "main",
        directives: [],
        template: `
            &lt;button
                (tap) = "onTapMe()"
                text = "tap me" /&gt;
        `
    })
    class MainPage {
        onTapMe() {
            alert("Hello from Angular 2");
        }
        // long coment pushing the right column further right !!!
    }
    </code></pre>
  </div>
  <div class="column">
  
  </div>
</div>
