#### Details and Summary
Content can be collapsed using HTML's [`<details>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details) and [`<summary>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/summary) tags. This is especially useful for collapsing long logs so they take up less screen space.
<p>
<details>
<summary>Click me to collapse/fold.</summary>
These details will remain hidden until expanded.
<pre><code>PASTE LOGS HERE</code></pre>
</details>
</p>
**Note:** Unfortunately Markdown is not supported inside these tags, as described by the [markdown specification](https://daringfireball.net/projects/markdown/syntax#html). You can work around this by using HTML, for example you can use `<pre><code>` tags instead of [code fences](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/user/markdown.md#code-and-syntax-highlighting).
```html
<details>
<summary>Click me to collapse/fold.</summary>
These details will remain hidden until expanded.
<pre><code>PASTE LOGS HERE</code></pre>
</details>
```
