<p>Page zooming inevitably presents rendering artifacts in some components, both in Bootstrap and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.</p>

<p>While <code class="highlighter-rouge">:hover</code> isn’t possible on most touch devices, iOS emulates this behavior, resulting in “sticky” hover styles that persist after tapping one element. These hover styles are only removed when users tap another element. This behavior is considered largely undesirable and appears to not be an issue on Android or Windows devices.</p>

<p>Throughout our v4 alpha and beta releases, we included incomplete and commented out code for opting into a media query shim that would disable hover styles in touch device browsers that emulate hovering. This work was never fully completed or enabled, but to avoid complete breakage, we’ve opted to deprecate <a href="https://github.com/twbs/mq4-hover-shim">this shim</a> and keep the mixins as shortcuts for the pseudo-classes.</p>
