<h2>Shuffle with Flexbox (Bootstrap 4)</h2>
|
|
<p>On this page, I have added the minified bootstrap css file from the <a href="https://www.bootstrapcdn.com/">Bootstrap CDN</a> (which is also why some of the site-styles are being overriden).</p>
|
|
<p>The <a href="https://getbootstrap.com/docs/4.0/layout/grid/">Bootstrap 4 grid</a> system uses flexbox with padding for gutters.</p>
|
|
<p>The best way to handle this is to have the shuffle container element (<code>#grid</code> in this case), to be a <code>.row</code> so that all the shuffle items remain flex-items.</p>
|
|
<p class="mb-0">If you cannot make the shuffle container element a <code>.row</code>, you will need to set a <code>width</code> for each column (like <code>width: 25%;</code>).</p>

<p>The one change I've made to the grid is to allow grid columns to fit on mobile.</p>
|
|
<p>By default, bootstrap 4 grid gutters are 30px, even on mobile, and they use as 12 column grid. At 320px, each column would need to be 26.667px for 12 columns to fit, but since there is 30px of inner gutter, the columns are always >= 30px, so they don't fit for us.</p>
|
|
<p>If you're using Bootstrap's sass files, you can customize the gutter width via the <code>$grid-gutter-widths</code> map. In this example, I'm overriding it instead.</p>
