# Bootstrap 5.3 Content

Bootstrap provides typography, image, table, and other content styles built on top of Reboot, a normalized baseline.

## Reboot

Bootstrap Reboot normalizes default browser styles for consistent cross-browser rendering. It provides a foundation for the typography and content styles that follow.

### Code Elements

```html
<!-- Inline code -->
<p>Use <code>&lt;section&gt;</code> for page sections.</p>

<!-- Code blocks (use pre for preformatted text) -->
<pre><code>&lt;p&gt;Sample text here...&lt;/p&gt;
&lt;p&gt;And another line.&lt;/p&gt;</code></pre>

<!-- Variables -->
<var>y</var> = <var>m</var><var>x</var> + <var>b</var>

<!-- User input (keyboard) -->
<p>Press <kbd>Ctrl</kbd> + <kbd>C</kbd> to copy.</p>
<p>Or type <kbd>cd</kbd> to change directory.</p>

<!-- Nested kbd for key combinations -->
<kbd><kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd></kbd>

<!-- Sample output -->
<samp>This text is meant to be sample output from a program.</samp>
```

### Address

```html

  <strong>Company Name</strong><br>
  123 Main Street<br>
  City, State 12345<br>

## Typography

### Headings

Standard HTML headings with Bootstrap styling:

```html
<h1>h1. Bootstrap heading</h1>  <!-- 2.5rem -->
<h2>h2. Bootstrap heading</h2>  <!-- 2rem -->
<h3>h3. Bootstrap heading</h3>  <!-- 1.75rem -->
<h4>h4. Bootstrap heading</h4>  <!-- 1.5rem -->
<h5>h5. Bootstrap heading</h5>  <!-- 1.25rem -->
<h6>h6. Bootstrap heading</h6>  <!-- 1rem -->

<!-- Heading classes for non-heading elements -->
<p class="h1">h1 styled paragraph</p>
<p class="h3">h3 styled paragraph</p>
```

### Display Headings

Larger, more opinionated headings:

```html
<h1 class="display-1">Display 1</h1>  <!-- 5rem -->
<h1 class="display-2">Display 2</h1>  <!-- 4.5rem -->
<h1 class="display-3">Display 3</h1>  <!-- 4rem -->
<h1 class="display-4">Display 4</h1>  <!-- 3.5rem -->
<h1 class="display-5">Display 5</h1>  <!-- 3rem -->
<h1 class="display-6">Display 6</h1>  <!-- 2.5rem -->
```

### Lead Text

Make a paragraph stand out:

```html
<p class="lead">
  This is a lead paragraph. It stands out from regular paragraphs.
</p>
```

### Inline Text Elements

```html
<mark>Highlighted text</mark>
<del>Deleted text</del>
<s>Strikethrough (no longer accurate)</s>
<ins>Inserted text</ins>
<u>Underlined text</u>
<small>Fine print</small>
<strong>Bold text</strong>
<em>Italicized text</em>
```

<p class="fs-4">fs-4 text (1.5rem)</p>

<!-- Text decoration -->
<p class="text-decoration-underline">Underlined</p>
<p class="text-decoration-line-through">Line through</p>

```

### Text Alignment

  </figcaption>
</figure>
```

  <li>On this list</li>
</ul>

### Reset Color

```html
<!-- Inherit color from parent instead of link styling -->
<p class="text-muted">
  Muted text with a <a href="#" class="text-reset">reset link</a>.
</p>
```

### Customizing Headings

Add secondary, faded text to headings:

```html
<h3>
  Fancy display heading
  <small class="text-body-secondary">With faded secondary text</small>
</h3>

<h1 class="display-4">
  Display heading
  <small class="text-body-secondary">Secondary text</small>
</h1>
```

### Responsive Font Sizes

Bootstrap 5 enables RFS (Responsive Font Sizes) by default, automatically scaling `font-size` based on viewport dimensions. See `references/typography-reference.md` for RFS details and Sass customization options.

```html
<img src="..." class="img-fluid" alt="Responsive image">
