Additional styling is done only with classes. For example, we reboot some `<table>` 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 `<html>` and `<body>` 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 `<html>`, but `16px` is assumed (the browser default). `font-size: 1rem` is applied on the `<body>` for easy responsive type-scaling via media queries while respecting user preferences and ensuring a more accessible approach. -- The `<body>` 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 `<body>` 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 %} -$font-family-sans-serif: - // Safari for OS X and iOS (San Francisco) - -apple-system, - // Chrome < 56 for OS X (San Francisco) - BlinkMacSystemFont, - // Windows - "Segoe UI", - // Android - "Roboto", - // Basic web fallback - "Helvetica Neue", Arial, sans-serif, - // Emoji fonts - "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol" !default; -{% endhighlight %} - -This `font-family` is applied to the `<body>` and automatically inherited globally throughout Bootstrap. To switch the global `font-family`, update `$font-family-base` and recompile Bootstrap. - -## Headings and paragraphs - -All heading elements—e.g., `<h1>`—and `<p>` are reset to have their `margin-top` removed. Headings have `margin-bottom: .5rem` added and paragraphs `margin-bottom: 1rem` for easy spacing. - -<table> - <thead> - <tr> - <th>Heading</th> - <th>Example</th> - </tr> - </thead> - <tbody> - <tr> - <td> - {% markdown %}`<h1></h1>`{% endmarkdown %} - </td> - <td><span class="h1">h1.

Here are some of the most notable changes: - -- `<fieldset>`s have no borders, padding, or margin so they can be easily used as wrappers for individual inputs or groups of inputs. -- `<legend>`s, like fieldsets, have also been restyled to be displayed as a heading of sorts. -- `<label>`s are set to `display: inline-block` to allow `margin` to be applied. -- `<input>`s, `<select>`s, `<textarea>`s, and `<button>`s are mostly addressed by Normalize, but Reboot removes their `margin` and sets `line-height: inherit`, too. -- `<textarea>`s are modified to only be resizable vertically as horizontal resizing often "breaks" page layout. - -These changes, and more, are demonstrated below. - -<form class="bd-example"> - <fieldset> - <legend>Example legend</legend> - - <p> - <label for="input">Example input</label> - <input type="text" id="input" placeholder="Example input"> - </p> - - <p> - <label for="select">Example select</label> - <select id="select"> - <option value="">Choose...</option> - <optgroup label="Option group 1"> - <option value="">Option 1</option> - <option value="">Option 2</option> - <option value="">Option 3</option> - </optgroup> - <optgroup label="Option group 2"> - <option value="">Option 4</option> - <option value="">Option 5</option> - <option value="">Option 6</option> - </optgroup> - </select> - </p> - - <p> - <label> - <input type="checkbox" value=""> - Check this checkbox - </label> - </p> - - <p> - <label> - <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked> - Option one is this and that - </label> - <label> - <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2"> - Option two is something else that's also super long to demonstrate the wrapping of these fancy form controls. - </label> - <label> - <input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled> - Option three is disabled - </label> - </p> - - <p> - <label for="textarea">Example textarea</label> - <textarea id="textarea" rows="3"></textarea> - </p> - - <p> - <label for="date">Example date</label> - <input type="date" id="date"> - </p> - - <p> - <label for="time">Example time</label> - <input type="time" id="time"> - </p> - - <p> - <label for="output">Example output</label> - <output name="result" id="output">100</output> - </p> - - <p> - <button type="submit">Button submit</button> - <input type="submit" value="Input submit button"> - <input type="button" value="Input button"> - </p> - - <p> - <button type="submit" disabled>Button submit</button> - <input type="submit" value="Input submit button" disabled> - <input type="button" value="Input button" disabled> - </p> - </fieldset> -</form> - -## Misc elements - -### Address - -The `<address>` element is updated to reset the browser default `font-style` from `italic` to `normal`. `line-height` is also now inherited, and `margin-bottom: 1rem` has been added. `<address>`s are for presenting contact information for the nearest ancestor (or an entire body of work). Preserve formatting by ending lines with `<br>`. - -<div class="bd-example"> - <address> - <strong>Twitter, Inc.</strong><br> - 1355 Market St, Suite 900<br> - San Francisco, CA 94103<br> - <abbr title="Phone">P:</abbr> (123) 456-7890 - </address> - - <address> - <strong>Full Name</strong><br> - <a href="mailto:#">first.last@example.com</a> - </address> -</div> - -### Blockquote - -The default `margin` on blockquotes is `1em 40px`, so we reset that to `0 0 1rem` for something more consistent with other elements. - -<div class="bd-example"> - <blockquote class="blockquote"> - <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p> - <footer>Someone famous in <cite title="Source Title">Source Title</cite></footer> - </blockquote> -</div> - -### Inline elements - -The `<abbr>` element receives basic styling to make it stand out amongst paragraph text. - -<div class="bd-example"> - Nulla <abbr title="attribute">attr</abbr> vitae elit libero, a pharetra augue. -</div> - -### Summary - -The default `cursor` on summary is `text`, so we reset that to `pointer` to convey that the element can be interacted with by clicking on it. - -<div class="bd-example"> - <details> - <summary>Some details</summary> - <p>More info about the details.</p> - </details> - - <details open> - <summary>Even more details</summary> - <p>Here are even more details about the details.</p> - </details> -</div> - -## HTML5 `[hidden]` attribute - -HTML5 adds [a new global attribute named `[hidden]`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden), which is styled as `display: none` by default. Borrowing an idea from [PureCSS](https://purecss.io/), we improve upon this default by making `[hidden] { display: none !important; }` to help prevent its `display` from getting accidentally overridden. While `[hidden]` isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem. - -{% highlight html %} -<input type="text" hidden> -{% endhighlight %} - -{% callout warning %} -##### jQuery incompatibility - -`[hidden]` is not compatible with jQuery's `$(...).hide()` and `$(...).show()` methods. Therefore, we don't currently especially endorse `[hidden]` over other techniques for managing the `display` of elements. -{% endcallout %} - -To merely toggle the visibility of an element, meaning its `display` is not modified and the element can still affect the flow of the document, use [the `.invisible` class]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/visibility/) instead.
