<p>This page is outdated and is no longer applicable to the latest versions of Bootstrap. It’s here purely for historical purposes now and will be removed in our next major release.

<p>Bootstrap currently works around several outstanding browser bugs in major browsers to deliver the best cross-browser experience possible. Some bugs, like those listed below, cannot be solved by us.</p>
|
|
<p>We publicly list browser bugs that are impacting us here, in the hopes of expediting the process of fixing them. For information on Bootstrap’s browser compatibility, <a href="/docs/4.6/getting-started/browsers-devices/#supported-browsers">see our browser compatibility docs</a>.</p>
