<h1>Responsive Auto Layout Columns</h1>
<p>In Bootstrap 5, there is an easy way to create equal width columns: just use the <code>.col-md</code> class on a specified number of col elements. Bootstrap will recognize how many columns there are, and each column will get the same width.</p>
<p>If the screen size is <strong>less than 768px</strong>, the columns will stack horizontally.</p>
