Creates a responsive layout with a content area and a sidebar.

- Use `display: grid` on the parent container, to create a grid layout.
- Use `minmax()` for the second column (sidebar) to allow it to take up between `150px` and `20%`.
- Use `1fr` for the first column (main content) to take up the rest of the remaining space.

```html
<div class="container">
  <main>
    This element is 1fr large.
  </main>
  <aside>
    Min: 150px / Max: 20%
  </aside>
</div>
```

```css
.container {
  display: grid;
  grid-template-columns: 1fr minmax(150px, 20%);
  height: 100px;
}

main, aside {
  padding: 12px;
  text-align: center;
}

main {
  background: #d4f2c4;
}

aside {
  background: #81cfd9;
}
```
