         <p>Several Bootstrap components utilize <code>z-index</code>, the CSS property that helps control layout by providing a third axis to arrange content. We utilize a default z-index scale in Bootstrap that&rsquo;s been designed to properly layer navigation, tooltips and popovers, modals, and more.</p>
 <p>These higher values start at an arbitrary number, high and specific enough to ideally avoid conflicts. We need a standard set of these across our layered components—tooltips, popovers, navbars, dropdowns, modals—so we can be reasonably consistent in the behaviors. There&rsquo;s no reason we couldn&rsquo;t have used <code>100</code>+ or <code>500</code>+.</p>
