<h2 id="introduction">Introduction</h2>
|
||
|
||
<p>In Bootstrap 3, theming was largely driven by variable overrides in LESS, custom CSS, and a separate theme stylesheet that we included in our <code class="highlighter-rouge">dist</code> files. With some effort, one could completely redesign the look of Bootstrap 3 without touching the core files. Bootstrap 4 provides a familiar, but slightly different approach.</p>
|
||
|
||
<p>Now, theming is accomplished by Sass variables, Sass maps, and custom CSS. There’s no more dedicated theme stylesheet; instead, you can enable the built-in theme to add gradients, shadows, and more.</p>
|
||
|
||
<h2 id="sass">Sass</h2>
|
||
|
||
<p>Utilize our source Sass files to take advantage of variables, maps, mixins, and more.</p>
|
||
|
||
<h3 id="file-structure">File structure</h3>
|
||
|
||
<p>Whenever possible, avoid modifying Bootstrap’s core files. For Sass, that means creating your own stylesheet that imports Bootstrap so you can modify and extend it. Assuming you’re using a package manager like npm, you’ll have a file structure that looks like this:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-plaintext" data-lang="plaintext">your-project/
|
||
├── scss
|
||
│ └── custom.scss
|
||
└── node_modules/
|
||
└── bootstrap
|
||
├── js
|
||
└── scss</code></pre></figure>
|
||
|
||
<p>If you’ve downloaded our source files and aren’t using a package manager, you’ll want to manually setup something similar to that structure, keeping Bootstrap’s source files separate from your own.</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-plaintext" data-lang="plaintext">your-project/
|
||
├── scss
|
||
│ └── custom.scss
|
||
└── bootstrap/
|
||
├── js
|
||
└── scss</code></pre></figure>
|
||
|
||
<h3 id="importing">Importing</h3>
|
||
|
||
<p>In your <code class="highlighter-rouge">custom.scss</code>, you’ll import Bootstrap’s source Sass files. You have two options: include all of Bootstrap, or pick the parts you need. We encourage the latter, though be aware there are some requirements and dependencies across our components. You also will need to include some JavaScript for our plugins.</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="c1">// Custom.scss
|
||
// Option A: Include all of Bootstrap
|
||
</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/bootstrap"</span><span class="p">;</span></code></pre></figure>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="c1">// Custom.scss
|
||
// Option B: Include parts of Bootstrap
|
||
</span>
|
||
<span class="c1">// Required
|
||
</span><span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/functions"</span><span class="p">;</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/variables"</span><span class="p">;</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/mixins"</span><span class="p">;</span>
|
||
|
||
<span class="c1">// Optional
|
||
</span><span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/reboot"</span><span class="p">;</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/type"</span><span class="p">;</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/images"</span><span class="p">;</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/code"</span><span class="p">;</span>
|
||
<span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/grid"</span><span class="p">;</span></code></pre></figure>
|
||
|
||
<p>With that setup in place, you can begin to modify any of the Sass variables and maps in your <code class="highlighter-rouge">custom.scss</code>. You can also start to add parts of Bootstrap under the <code class="highlighter-rouge">// Optional</code> section as needed. We suggest using the full import stack from our <code class="highlighter-rouge">bootstrap.scss</code> file as your starting point.</p>
|
||
|
||
<h3 id="variable-defaults">Variable defaults</h3>
|
||
|
||
<p>Every Sass variable in Bootstrap 4 includes the <code class="highlighter-rouge">!default</code> flag allowing you to override the variable’s default value in your own Sass without modifying Bootstrap’s source code. Copy and paste variables as needed, modify their values, and remove the <code class="highlighter-rouge">!default</code> flag. If a variable has already been assigned, then it won’t be re-assigned by the default values in Bootstrap.</p>
|
||
|
||
<p>Variable overrides within the same Sass file can come before or after the default variables. However, when overriding across Sass files, your overrides must come before you import Bootstrap’s Sass files.</p>
|
||
|
||
<p>Here’s an example that changes the <code class="highlighter-rouge">background-color</code> and <code class="highlighter-rouge">color</code> for the <code class="highlighter-rouge"><body></code> when importing and compiling Bootstrap via npm:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="c1">// Your variable overrides
|
||
</span><span class="nv">$body-bg</span><span class="p">:</span> <span class="mh">#000</span><span class="p">;</span>
|
||
<span class="nv">$body-color</span><span class="p">:</span> <span class="mh">#111</span><span class="p">;</span>
|
||
|
||
<span class="c1">// Bootstrap and its default variables
|
||
</span><span class="k">@import</span> <span class="s2">"node_modules/bootstrap/scss/bootstrap"</span><span class="p">;</span></code></pre></figure>
|
||
|
||
<p>Repeat as necessary for any variable in Bootstrap, including the global options below.</p>
|
||
|
||
<h3 id="maps-and-loops">Maps and loops</h3>
|
||
|
||
<p>Bootstrap 4 includes a handful of Sass maps, key value pairs that make it easier to generate families of related CSS. We use Sass maps for our colors, grid breakpoints, and more. Just like Sass variables, all Sass maps include the <code class="highlighter-rouge">!default</code> flag and can be overridden and extended.</p>
|
||
|
||
<p>Some of our Sass maps are merged into empty ones by default. This is done to allow easy expansion of a given Sass map, but comes at the cost of making <em>removing</em> items from a map slightly more difficult.</p>
|
||
|
||
<h4 id="modify-map">Modify map</h4>
|
||
|
||
<p>To modify an existing color in our <code class="highlighter-rouge">$theme-colors</code> map, add the following to your custom Sass file:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nv">$theme-colors</span><span class="p">:</span> <span class="p">(</span>
|
||
<span class="s2">"primary"</span><span class="o">:</span> <span class="mh">#0074d9</span><span class="o">,</span>
|
||
<span class="s2">"danger"</span><span class="o">:</span> <span class="mh">#ff4136</span>
|
||
<span class="p">);</span></code></pre></figure>
|
||
|
||
<h4 id="add-to-map">Add to map</h4>
|
||
|
||
<p>To add a new color to <code class="highlighter-rouge">$theme-colors</code>, add the new key and value:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nv">$theme-colors</span><span class="p">:</span> <span class="p">(</span>
|
||
<span class="s2">"custom-color"</span><span class="o">:</span> <span class="mh">#900</span>
|
||
<span class="p">);</span></code></pre></figure>
|
||
|
||
<h4 id="remove-from-map">Remove from map</h4>
|
||
|
||
<p>To remove colors from <code class="highlighter-rouge">$theme-colors</code>, or any other map, use <code class="highlighter-rouge">map-remove</code>:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nv">$theme-colors</span><span class="p">:</span> <span class="nf">map-remove</span><span class="p">(</span><span class="nv">$theme-colors</span><span class="o">,</span> <span class="s2">"success"</span><span class="o">,</span> <span class="s2">"info"</span><span class="o">,</span> <span class="s2">"danger"</span><span class="p">);</span></code></pre></figure>
|
||
|
||
<h4 id="required-keys">Required keys</h4>
|
||
|
||
<p>Bootstrap assumes the presence of some specific keys within Sass maps as we used and extend these ourselves. As you customize the included maps, you may encounter errors where a specific Sass map’s key is being used.</p>
|
||
|
||
<p>For example, we use the <code class="highlighter-rouge">primary</code>, <code class="highlighter-rouge">success</code>, and <code class="highlighter-rouge">danger</code> keys from <code class="highlighter-rouge">$theme-colors</code> for links, buttons, and form states. Replacing the values of these keys should present no issues, but removing them may cause Sass compilation issues. In these instances, you’ll need to modify the Sass code that makes use of those values.</p>
|
||
|
||
<h3 id="functions">Functions</h3>
|
||
|
||
<p>Bootstrap utilizes several Sass functions, but only a subset are applicable to general theming. We’ve included three functions for getting values from the color maps:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="k">@function</span> <span class="nf">color</span><span class="p">(</span><span class="nv">$key</span><span class="o">:</span> <span class="s2">"blue"</span><span class="p">)</span> <span class="p">{</span>
|
||
<span class="k">@return</span> <span class="nf">map-get</span><span class="p">(</span><span class="nv">$colors</span><span class="o">,</span> <span class="nv">$key</span><span class="p">);</span>
|
||
<span class="p">}</span>
|
||
|
||
<span class="k">@function</span> <span class="nf">theme-color</span><span class="p">(</span><span class="nv">$key</span><span class="o">:</span> <span class="s2">"primary"</span><span class="p">)</span> <span class="p">{</span>
|
||
<span class="k">@return</span> <span class="nf">map-get</span><span class="p">(</span><span class="nv">$theme-colors</span><span class="o">,</span> <span class="nv">$key</span><span class="p">);</span>
|
||
<span class="p">}</span>
|
||
|
||
<span class="k">@function</span> <span class="nf">gray</span><span class="p">(</span><span class="nv">$key</span><span class="o">:</span> <span class="s2">"100"</span><span class="p">)</span> <span class="p">{</span>
|
||
<span class="k">@return</span> <span class="nf">map-get</span><span class="p">(</span><span class="nv">$grays</span><span class="o">,</span> <span class="nv">$key</span><span class="p">);</span>
|
||
<span class="p">}</span></code></pre></figure>
|
||
|
||
<p>These allow you to pick one color from a Sass map much like how you’d use a color variable from v3.</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nc">.custom-element</span> <span class="p">{</span>
|
||
<span class="nl">color</span><span class="p">:</span> <span class="nf">gray</span><span class="p">(</span><span class="s2">"100"</span><span class="p">);</span>
|
||
<span class="nl">background-color</span><span class="p">:</span> <span class="nf">theme-color</span><span class="p">(</span><span class="s2">"dark"</span><span class="p">);</span>
|
||
<span class="p">}</span></code></pre></figure>
|
||
|
||
<p>We also have another function for getting a particular <em>level</em> of color from the <code class="highlighter-rouge">$theme-colors</code> map. Negative level values will lighten the color, while higher levels will darken.</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="k">@function</span> <span class="nf">theme-color-level</span><span class="p">(</span><span class="nv">$color-name</span><span class="o">:</span> <span class="s2">"primary"</span><span class="o">,</span> <span class="nv">$level</span><span class="o">:</span> <span class="m">0</span><span class="p">)</span> <span class="p">{</span>
|
||
<span class="nv">$color</span><span class="p">:</span> <span class="nf">theme-color</span><span class="p">(</span><span class="nv">$color-name</span><span class="p">);</span>
|
||
<span class="nv">$color-base</span><span class="p">:</span> <span class="nf">if</span><span class="p">(</span><span class="nv">$level</span> <span class="o">></span> <span class="m">0</span><span class="o">,</span> <span class="mh">#000</span><span class="o">,</span> <span class="mh">#fff</span><span class="p">);</span>
|
||
<span class="nv">$level</span><span class="p">:</span> <span class="nf">abs</span><span class="p">(</span><span class="nv">$level</span><span class="p">);</span>
|
||
|
||
<span class="k">@return</span> <span class="nf">mix</span><span class="p">(</span><span class="nv">$color-base</span><span class="o">,</span> <span class="nv">$color</span><span class="o">,</span> <span class="nv">$level</span> <span class="o">*</span> <span class="nv">$theme-color-interval</span><span class="p">);</span>
|
||
<span class="p">}</span></code></pre></figure>
|
||
|
||
<p>In practice, you’d call the function and pass in two parameters: the name of the color from <code class="highlighter-rouge">$theme-colors</code> (e.g., primary or danger) and a numeric level.</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nc">.custom-element</span> <span class="p">{</span>
|
||
<span class="nl">color</span><span class="p">:</span> <span class="nf">theme-color-level</span><span class="p">(</span><span class="n">primary</span><span class="o">,</span> <span class="m">-10</span><span class="p">);</span>
|
||
<span class="p">}</span></code></pre></figure>
|
||
|
||
<p>Additional functions could be added in the future or your own custom Sass to create level functions for additional Sass maps, or even a generic one if you wanted to be more verbose.</p>
|
||
|
||
<h3 id="color-contrast">Color contrast</h3>
|
||
|
||
<p>One additional function we include in Bootstrap is the color contrast function, <code class="highlighter-rouge">color-yiq</code>. It utilizes the <a href="https://en.wikipedia.org/wiki/YIQ">YIQ color space</a> to automatically return a light (<code class="highlighter-rouge">#fff</code>) or dark (<code class="highlighter-rouge">#111</code>) contrast color based on the specified base color. This function is especially useful for mixins or loops where you’re generating multiple classes.</p>
|
||
|
||
<p>For example, to generate color swatches from our <code class="highlighter-rouge">$theme-colors</code> map:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="k">@each</span> <span class="nv">$color</span><span class="o">,</span> <span class="nv">$value</span> <span class="n">in</span> <span class="nv">$theme-colors</span> <span class="p">{</span>
|
||
<span class="nc">.swatch-</span><span class="si">#{</span><span class="nv">$color</span><span class="si">}</span> <span class="p">{</span>
|
||
<span class="nl">color</span><span class="p">:</span> <span class="nf">color-yiq</span><span class="p">(</span><span class="nv">$value</span><span class="p">);</span>
|
||
<span class="p">}</span>
|
||
<span class="p">}</span></code></pre></figure>
|
||
|
||
<p>It can also be used for one-off contrast needs:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nc">.custom-element</span> <span class="p">{</span>
|
||
<span class="nl">color</span><span class="p">:</span> <span class="nf">color-yiq</span><span class="p">(</span><span class="mh">#000</span><span class="p">);</span> <span class="c1">// returns `color: #fff`
|
||
</span><span class="p">}</span></code></pre></figure>
|
||
|
||
<p>You can also specify a base color with our color map functions:</p>
|
||
|
||
<figure class="highlight"><pre><code class="language-scss" data-lang="scss"><span class="nc">.custom-element</span> <span class="p">{</span>
|
||
<span class="nl">color</span><span class="p">:</span> <span class="nf">color-yiq</span><span class="p">(</span><span class="nf">theme-color</span><span class="p">(</span><span class="s2">"dark"</span><span class="p">));</span> <span class="c1">// returns `color: #fff`
|
||
</span><span class="p">}</span></code></pre></figure>
|
||
|
||
<h2 id="sass-options">Sass options</h2>
|
||
|
||
<p>Customize Bootstrap 4 with our built-in custom variables file and easily toggle global CSS preferences with new <code class="highlighter-rouge">$enable-*</code> Sass variables. Override a variable’s value and recompile with <code class="highlighter-rouge">npm run test</code> as needed.</p>

<h2 id="color">Color</h2>
|
||
|
||
<p>Many of Bootstrap’s 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, are 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>Add, remove, or modify values within the map to update how they’re 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">${color}</code> variables and this Sass map.</p>
|
||
|
||
<h2 id="components">Components</h2>
|
||
|
||
<p>Many of Bootstrap’s components and utilities are built with <code class="highlighter-rouge">@each</code> loops that iterate over a Sass map. This is especially helpful for generating variants of a component by our <code class="highlighter-rouge">$theme-colors</code> and creating responsive variants for each breakpoint. As you customize these Sass maps and recompile, you’ll automatically see your changes reflected in these loops.</p>
|
||
|
||
<h3 id="modifiers">Modifiers</h3>
|
||
|
||
<p>Many of Bootstrap’s components are built with a base-modifier class approach. This means the bulk of the styling is contained to a base class (e.g., <code class="highlighter-rouge">.btn</code>) while style variations are confined to modifier classes (e.g., <code class="highlighter-rouge">.btn-danger</code>). These modifier classes are built from the <code class="highlighter-rouge">$theme-colors</code> map to make customizing the number and name of our modifier classes.</p>
|
||
|
||
<p>Here are two examples of how we loop over the <code class="highlighter-rouge">$theme-colors</code> map to generate modifiers to the <code class="highlighter-rouge">.alert</code> component and all our <code class="highlighter-rouge">.bg-*</code> background utilities.</p>
