+title: Content body
+description: Use the `.content-body` wrapper class to make long form content more easily without the need for specifying Bootstrap classes on every element. Especially useful for converting Markdown or MDX to HTML, or simply for making content heavy pages more readable.
+toc: true
+---
+
+## How it works
+
+Wrap your content in the `.content-body` class to get modified font-size, line-height, and spacing specifically designed for long form content that originals from source Markdown files or WYSIWYG editors. Here's what we do with that class:
+
+- Set a base `font-size`, `line-height`, and some local CSS variables on the parent element.
+- Normalize the spacing of lists
+- Set a default `margin-bottom` for headings.
+- Style blockquotes, code, and other inline elements.
+
+## Example
+
+This is an example of source Markdown that shows several types of HTML content supported in this `.content-body` wrapper class.
+
+<div class="bd-example content-body">
+# Lorem ipsum dolor sit amet
+Cum sociis natoque penatibus et magnis [dis parturient montes](#), nascetur ridiculus mus. *Aenean eu leo quam.* Pellentesque ornare sem lacinia quam venenatis vestibulum. Sed posuere consectetur est at lobortis. Cras mattis consectetur purus sit amet fermentum.
+
+> Curabitur blandit tempus porttitor. Nullam quis risus eget urna mollis ornare vel eu leo. Nullam id dolor id nibh ultricies vehicula ut id elit.
+
+Etiam porta **sem malesuada magna** mollis euismod. Cras mattis consectetur purus sit amet fermentum. Aenean lacinia bibendum nulla sed consectetur.
+
+## Inline HTML elements
+
+HTML defines a long list of available inline tags, a complete list of which can be found on the [Mozilla Developer Network](https://developer.mozilla.org/en-US/docs/Web/HTML/Element).
+
+- **To bold text**, use `<strong>`.
+- *To italicize text*, use `<em>`.
+- <mark>To highlight</mark>, use `<mark>`.
+- Abbreviations, like <abbr title="HyperText Markup Langage">HTML</abbr> should use `<abbr>`, with an optional `title` attribute for the full phrase.
+- Citations, like <cite>&mdash; Mark Otto</cite>, should use `<cite>`.
+- <del>Deleted</del> text should use `<del>` and <ins>inserted</ins> text should use `<ins>`.
+- Superscript <sup>text</sup> uses `<sup>` and subscript <sub>text</sub> uses `<sub>`.
+
+Most of these elements are styled by browsers with few modifications on our part.
+
+## Heading
+
+Vivamus sagittis lacus vel augue rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Morbi leo risus, porta ac consectetur ac, vestibulum at eros.
+
+### Code
+
+Inline code is available with the `<code>` element. Snippets of multiple lines of code are supported through Rouge. Longer lines will automatically scroll horizontally when needed. You may also use code fencing (triple backticks) for rendering code.
+
+```
+// Example can be run directly in your JavaScript console
+
+// Create a function that takes two arguments and returns the sum of those arguments
+var adder = new Function("a", "b", "return a + b");
+
+// Call the function
+adder(2, 6);
+// > 8
+```
