<h2 id="approach">Approach</h2>
|
||
|
||
<p>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 <code class="highlighter-rouge"><table></code> styles for a simpler baseline and later provide <code class="highlighter-rouge">.table</code>, <code class="highlighter-rouge">.table-bordered</code>, and more.</p>
|
||
|
||
<p>Here are our guidelines and reasons for choosing what to override in Reboot:</p>
|
||
|
||
<ul>
|
||
<li>Update some browser default values to use <code class="highlighter-rouge">rem</code>s instead of <code class="highlighter-rouge">em</code>s for scalable component spacing.</li>
|
||
<li>Avoid <code class="highlighter-rouge">margin-top</code>. Vertical margins can collapse, yielding unexpected results. More importantly though, a single direction of <code class="highlighter-rouge">margin</code> is a simpler mental model.</li>
|
||
<li>For easier scaling across device sizes, block elements should use <code class="highlighter-rouge">rem</code>s for <code class="highlighter-rouge">margin</code>s.</li>
|
||
<li>Keep declarations of <code class="highlighter-rouge">font</code>-related properties to a minimum, using <code class="highlighter-rouge">inherit</code> whenever possible.</li>
|
||
</ul>
|
||
|
||
<h2 id="page-defaults">Page defaults</h2>
|
||
|
||
<p>The <code class="highlighter-rouge"><span class="nt"><html></span></code> and <code class="highlighter-rouge"><body></code> elements are updated to provide better page-wide defaults. More specifically:</p>
|
||
|
||
<ul>
|
||
<li>The <code class="highlighter-rouge">box-sizing</code> is globally set on every element—including <code class="highlighter-rouge">*:before</code> and <code class="highlighter-rouge">*:after</code>, to <code class="highlighter-rouge">border-box</code>. This ensures that the declared width of element is never exceeded due to padding or border.
|
||
<ul>
|
||
<li>No base <code class="highlighter-rouge">font-size</code> is declared on the <code class="highlighter-rouge"><span class="nt"><html></span></code>, but <code class="highlighter-rouge">16px</code> is assumed (the browser default). <code class="highlighter-rouge">font-size: 1rem</code> is applied on the <code class="highlighter-rouge"><body></code> for easy responsive type-scaling via media queries while respecting user preferences and ensuring a more accessible approach.</li>
|
||
</ul>
|
||
</li>
|
||
<li>The <code class="highlighter-rouge"><body></code> also sets a global <code class="highlighter-rouge">font-family</code>, <code class="highlighter-rouge">line-height</code>, and <code class="highlighter-rouge">text-align</code>. This is inherited later by some form elements to prevent font inconsistencies.</li>
|
||
<li>For safety, the <code class="highlighter-rouge"><body></code> has a declared <code class="highlighter-rouge">background-color</code>, defaulting to <code class="highlighter-rouge">#fff</code>.</li>

</ul>

<h2 id="native-font-stack">Native font stack</h2>
|

<p>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.

<p>Various form elements have been rebooted for simpler base styles. Here are some of the most notable changes:</p>
|
||
|
||
<ul>
|
||
<li><code class="highlighter-rouge"><fieldset></code>s have no borders, padding, or margin so they can be easily used as wrappers for individual inputs or groups of inputs.</li>
|
||
<li><code class="highlighter-rouge"><legend></code>s, like fieldsets, have also been restyled to be displayed as a heading of sorts.</li>
|
||
<li><code class="highlighter-rouge"><label></code>s are set to <code class="highlighter-rouge">display: inline-block</code> to allow <code class="highlighter-rouge">margin</code> to be applied.</li>
|
||
<li><code class="highlighter-rouge"><input></code>s, <code class="highlighter-rouge"><select></code>s, <code class="highlighter-rouge"><textarea></code>s, and <code class="highlighter-rouge"><button></code>s are mostly addressed by Normalize, but Reboot removes their <code class="highlighter-rouge">margin</code> and sets <code class="highlighter-rouge">line-height: inherit</code>, too.</li>
|
||
<li><code class="highlighter-rouge"><textarea></code>s are modified to only be resizable vertically as horizontal resizing often “breaks” page layout.</li>

Borrowing an idea from <a href="https://purecss.io">PureCSS</a>, we improve upon this default by making <code class="highlighter-rouge">[hidden] { display: none !important; }</code> to help prevent its <code class="highlighter-rouge">display</code> from getting accidentally overridden. While <code class="highlighter-rouge">[hidden]</code> isn’t natively supported by IE10, the explicit declaration in our CSS gets around that problem.</p>

|

<p><code class="highlighter-rouge">[hidden]</code> is not compatible with jQuery’s <code class="highlighter-rouge">$(...).hide()</code> and <code class="highlighter-rouge">$(...).show()</code> methods. This could potentially change in jQuery 3, but we’re not holding our breath. Therefore, we don’t currently especially endorse <code class="highlighter-rouge">[hidden]</code> over other techniques for managing the <code class="highlighter-rouge">display</code> of elements.</p>
|

</div>
|
||
|
||
<p>To merely toggle the visibility of an element, meaning its <code class="highlighter-rouge">display</code> is not modified and the element can still affect the flow of the document, use <a href="/bootstrap-material-design/docs/4.0/utilities/visibility/">the <code class="highlighter-rouge">.invisible</code> class</a> instead.</p>

||
<h2 id="click-delay-optimization-for-touch">Click delay optimization for touch</h2>
|
||
|
||
<p>Traditionally, browsers on touchscreen devices have a delay of approximately 300ms between the end of a “tap” – the moment when a finger/stylus is lifted from screen – and the <a href="https://developer.mozilla.org/en-US/docs/Web/Events/click"><code class="highlighter-rouge">click</code> event</a> being fired. This delay is necessary for these browsers to correctly handle “double-tap to zoom” gestures without prematurely triggering actions or links after the first “tap”, but it can make your site feel slightly sluggish and unresponsive.</p>
|
||
|
||
<p>Most mobile browsers automatically optimize away this 300ms delay for sites that use the <code class="highlighter-rouge">width=device-width</code> property as part of their <a href="/bootstrap-material-design/docs/4.0/getting-started/introduction/#responsive-meta-tag">responsive meta tag</a> (as well as for sites that disable zooming, for instance with <code class="highlighter-rouge">user-scalable=no</code>, though this practice is strongly discouraged for accessibility and usability reasons). The biggest exceptions here are IE11 on Windows Phone 8.1, and iOS Safari (and any other iOS WebView-based browser) <a href="https://webkit.org/blog/5610/more-responsive-tapping-on-ios/">prior to iOS 9.3</a>.</p>
|
||
|
||
<p>On touch-enabled laptop/desktop devices, IE11 and Microsoft Edge are currently the only browsers with “double-tap to zoom” functionality. As the <a href="/bootstrap-material-design/docs/4.0/getting-started/introduction/#responsive-meta-tag">responsive meta tag</a> is ignored by all desktop browsers, using <code class="highlighter-rouge">width=device-width</code> will have no effect on the 300ms delay here.</p>

<p>To address this problem in IE11 and Microsoft Edge on desktop, as well as IE11 on Windows Phone 8.1, Bootstrap explicitly uses the <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/touch-action"><code class="highlighter-rouge">touch-action:manipulation</code> CSS property</a> on all interactive elements (such as buttons and links). This property essentially disables double-tap functionality on those elements, eliminating the 300ms delay.</p>
|
||
|
||
<p>In the case of old iOS versions (prior to 9.3), the suggested approach is to use additional scripts such as <a href="https://github.com/ftlabs/fastclick">FastClick</a> to explicitly work around the delay.</p>
|
||

<p>For further details, see the compatibility table for <a href="https://patrickhlauke.github.io/touch/tests/results/#suppressing-300ms-delay">suppressing 300ms delay for touchscreen interactions</a>.</p>
