<h2 id="customizing-variables">Customizing variables</h2>
<p>Every Sass variable in Bootstrap 4 includes the <code class="highlighter-rouge">!default</code> flag, meaning you can override that default value in your own Sass even after that original variables been defined. Copy and paste variables as needed, modify the values, remove the <code class="highlighter-rouge">!default</code> flag, and recompile.</p>
<p>For example, to change out the <code class="highlighter-rouge">background-color</code> and <code class="highlighter-rouge">color</code> for the <code class="highlighter-rouge">&lt;body&gt;</code>, youd do the following:</p>
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nv">$body-bg</span><span class="p">:</span> <span class="nv">$gray-900</span><span class="p">;</span>
<span class="nv">$body-color</span><span class="p">:</span> <span class="nv">$gray-600</span><span class="p">;</span></code></pre></figure>
<p>Do the same for any variable you need to override, including the global options listed below.</p>
<h2 id="global-options">Global options</h2>
<p>Customize Bootstrap 4 with our built-in custom variables file and easily toggle global CSS preferences with new <code class="highlighter-rouge">$enable-*</code> Sass variables. Override a variables value and recompile with <code class="highlighter-rouge">npm run test</code> as needed.</p>
<p>You can find and customize these variables for key global options in our <code class="highlighter-rouge">_variables.scss</code> file.</p>

<h2 id="color">Color</h2>
<p>Many of Bootstraps various components and utilities are built through a series of colors defined in a Sass map. This map can be looped over in Sass to quickly generate a series of rulesets.</p>
<h3 id="all-colors">All colors</h3>
<p>All colors available in Bootstrap 4, available as Sass variables and a Sass map in our <code class="highlighter-rouge">scss/_variables.scss</code> file. This will be expanded upon in subsequent minor releases to add additional shades, much like the <a href="#grays">grayscale palette</a> we already include.</p>

<p>Heres how you can use these in your Sass:</p>

<p><a href="/bootstrap-material-design/docs/4.0/utilities/colors/">Color utility classes</a> are also available for setting <code class="highlighter-rouge">color</code> and <code class="highlighter-rouge">background-color</code>.</p>
<div class="bd-callout bd-callout-info">
<p>In the future, well aim to provide Sass maps and variables for shades of each color as weve done with the grayscale colors below.</p>
</div>
<h3 id="theme-colors">Theme colors</h3>
<p>We use a subset of all colors to create a smaller color palette for generating color schemes, also available as Sass variables and a Sass map in our <code class="highlighter-rouge">scss/_variables.scss</code> file.</p>

<p>Within <code class="highlighter-rouge">_variables.scss</code>, youll find our color variables and Sass map. Heres an example of the <code class="highlighter-rouge">$colors</code> Sass map:</p>
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nv">$colors</span><span class="p">:</span> <span class="p">(</span>

<span class="no">green</span><span class="o">:</span> <span class="nv">$green</span><span class="o">,</span>

<span class="p">)</span> <span class="o">!</span><span class="nb">default</span><span class="p">;</span></code></pre></figure>
<p>Add, remove, or modify values within the map to update how theyre used in many other components. Unfortunately at this time, not <em>every</em> component utilizes this Sass map. Future updates will strive to improve upon this. Until then, plan on making use of the <code class="highlighter-rouge">${color}</code> variables and this Sass map.</p>
