+Anytime you need to display a piece of content—like an image with an optional caption, consider using a ``.
+
+Use the included `.figure` , `.figure-img` and `.figure-caption` classes to provide some baseline styles for the HTML5 `` and `` elements. Images in figures have no explicit size, so be sure to add the `.img-fluid` class to your `
` to make it responsive.

+## Responsive images
+
+Images in Bootstrap are made responsive with `.img-fluid`. `max-width: 100%;` and `height: auto;` are applied to the image so that it scales with the parent element.

+##### SVG images and IE 10
+
+In Internet Explorer 10, SVG images with `.img-fluid` are disproportionately sized. To fix this, add `width: 100% \9;` where necessary. This fix improperly sizes other image formats, so Bootstrap doesn't apply it automatically.
+{% endcallout %}

+## Image thumbnails

+In addition to our [border-radius utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.

+title: Reboot
+description: Reboot, a collection of element-specific CSS changes in a single file, kickstart Bootstrap to provide an elegant, consistent, and simple baseline to build upon.
+group: content
+redirect_from: "/docs/4.0/content/"
+toc: true
+---
+
+## Approach
+
+Reboot builds upon Normalize, providing many HTML elements with somewhat opinionated styles using only element selectors. Additional styling is done only with classes. For example, we reboot some `` styles for a simpler baseline and later provide `.table`, `.table-bordered`, and more.
+
+Here are our guidelines and reasons for choosing what to override in Reboot:
+
+- Update some browser default values to use `rem`s instead of `em`s for scalable component spacing.
+- Avoid `margin-top`. Vertical margins can collapse, yielding unexpected results. More importantly though, a single direction of `margin` is a simpler mental model.
+- For easier scaling across device sizes, block elements should use `rem`s for `margin`s.
+- Keep declarations of `font`-related properties to a minimum, using `inherit` whenever possible.
+
+## Page defaults
+
+The `` and `` elements are updated to provide better page-wide defaults. More specifically:
+
+- The `box-sizing` is globally set on every element—including `*::before` and `*::after`, to `border-box`. This ensures that the declared width of element is never exceeded due to padding or border.
+ - No base `font-size` is declared on the ``, but `16px` is assumed (the browser default). `font-size: 1rem` is applied on the `` for easy responsive type-scaling via media queries while respecting user preferences and ensuring a more accessible approach.
+- The `` also sets a global `font-family`, `line-height`, and `text-align`. This is inherited later by some form elements to prevent font inconsistencies.
+- For safety, the `` has a declared `background-color`, defaulting to `#fff`.
+
+## Native font stack
+
+The default web fonts (Helvetica Neue, Helvetica, and Arial) have been dropped in Bootstrap 4 and replaced with a "native font stack" for optimum text rendering on every device and OS. Read more about [native font stacks in this *Smashing Magazine* article](https://www.smashingmagazine.com/2015/11/using-system-ui-fonts-practical-guide/).
+
+{% highlight sass %}
+$font-family-sans-serif:
+ // Safari for OS X and iOS (San Francisco)
+ -apple-system,
+ // Chrome < 56 for OS X (San Francisco)
+ BlinkMacSystemFont,
+ // Windows
+ "Segoe UI",
+ // Android
+ "Roboto",
+ // Basic web fallback
+ "Helvetica Neue", Arial, sans-serif,
+ // Emoji fonts
+ "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol" !default;
+{% endhighlight %}
+
+This `font-family` is applied to the `` and automatically inherited globally throughout Bootstrap. To switch the global `font-family`, update `$font-family-base` and recompile Bootstrap.
+
+## Headings and paragraphs
+
+All heading elements—e.g., ``—and `
` are reset to have their `margin-top` removed. Headings have `margin-bottom: .5rem` added and paragraphs `margin-bottom: 1rem` for easy spacing.
+
+
+
+
+ | Heading |
+ Example |
+
+
+
+
+ |
+ {% markdown %}``{% endmarkdown %}
+ |
+ h1. Bootstrap heading |
+
+
+ |
+ {% markdown %}``{% endmarkdown %}
+ |
+ h2. Bootstrap heading |
+
+
+ |
+ {% markdown %}``{% endmarkdown %}
+ |
+ h3. Bootstrap heading |
+
+
+ |
+ {% markdown %}``{% endmarkdown %}
+ |
+ h4. Bootstrap heading |
+
+
+ |
+ {% markdown %}``{% endmarkdown %}
+ |
+ h5. Bootstrap heading |
+
+
+ |
+ {% markdown %}``{% endmarkdown %}
+ |
+ h6. Bootstrap heading |
+
+
+
+
+## Lists
+
+All lists—``, ``, and ``—have their `margin-top` removed and a `margin-bottom: 1rem`. Nested lists have no `margin-bottom`.
+
+
+{% markdown %}
+* Lorem ipsum dolor sit amet
+* Consectetur adipiscing elit
+* Integer molestie lorem at massa
+* Facilisis in pretium nisl aliquet
+* Nulla volutpat aliquam velit
+ * Phasellus iaculis neque
+ * Purus sodales ultricies
+ * Vestibulum laoreet porttitor sem
+ * Ac tristique libero volutpat at
+* Faucibus porta lacus fringilla vel
+* Aenean sit amet erat nunc
+* Eget porttitor lorem
+
+1. Lorem ipsum dolor sit amet
+2. Consectetur adipiscing elit
+3. Integer molestie lorem at massa
+4. Facilisis in pretium nisl aliquet
+5. Nulla volutpat aliquam velit
+6. Faucibus porta lacus fringilla vel
+7. Aenean sit amet erat nunc
+8. Eget porttitor lorem
+{% endmarkdown %}
+
+
+For simpler styling, clear hierarchy, and better spacing, description lists have updated `margin`s. `- `s reset `margin-left` to `0` and add `margin-bottom: .5rem`. `
- `s are **bolded**.
+
+
+{% markdown %}
+
+ - Description lists
+ - A description list is perfect for defining terms.
+ - Euismod
+ - Vestibulum id ligula porta felis euismod semper eget lacinia odio sem.
+ - Donec id elit non mi porta gravida at eget metus.
+ - Malesuada porta
+ - Etiam porta sem malesuada magna mollis euismod.
+
+{% endmarkdown %}
+
+
+## Preformatted text
+
+The `` element is reset to remove its `margin-top` and use `rem` units for its `margin-bottom`.
+
+
+{% markdown %}
+
+.example-element {
+ margin-bottom: 1rem;
+}
+
+{% endmarkdown %}
+
+
+## Tables
+
+Tables are slightly adjusted to style ``s, collapse borders, and ensure consistent `text-align` throughout. Additional changes for borders, padding, and more come with [the `.table` class]({{ site.baseurl }}/docs/{{ site.docs_version }}/content/tables/).
+
+
+
+
+ This is an example table, and this is its caption to describe the contents.
