Generally speaking, Bootstrap supports the latest versions of each major platform’s default browsers. Note that proxy browsers (such as Opera Mini, Opera Mobile’s Turbo mode, UC Browser Mini, Amazon Silk) are not supported.
| Chrome | Firefox | Safari | Android Browser & WebView | |
|---|---|---|---|---|
| Android | Supported | Supported | — | v6.0+ |
| iOS | Supported | Supported | Supported | — |
Desktop browsers
Similarly, the latest versions of most desktop browsers are supported.
| Chrome | Firefox | Microsoft Edge | Opera | Safari | |
|---|---|---|---|---|---|
| Mac | Supported | Supported | Supported | Supported | Supported |
| Windows | Supported | Supported | Supported | Supported | — |
For Firefox, in addition to the latest normal stable release, we also support the latest Extended Support Release (ESR) version of Firefox.
Unofficially, Bootstrap should look and behave well enough in Chromium and Chrome for Linux, and Firefox for Linux, though they are not officially supported.
Internet Explorer
Internet Explorer is not supported. If you require Internet Explorer support, please use Bootstrap v4.
Modals and dropdowns on mobile
Overflow and scrolling
Support for overflow: hidden; on the <body> element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices’ browsers, the <body> content will begin to scroll. See Chrome bug #175502 (fixed in Chrome v40) and WebKit bug #153852.
iOS text fields and scrolling
As of iOS 9.2, while a modal is open, if the initial touch of a scroll gesture is within the boundary of a textual <input> or a <textarea>, the <body> content underneath the modal will be scrolled instead of the modal itself. See WebKit bug #153856.
Navbar Dropdowns
The .dropdown-backdrop element isn’t used on iOS in the nav because of the complexity of z-indexing. Thus, to close dropdowns in navbars, you must directly click the dropdown element (or any other element which will fire a click event in iOS).
Browser zooming
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.
Validators
In order to provide the best possible experience to old and buggy browsers, Bootstrap uses CSS browser hacks in several places to target special CSS to certain browser versions in order to work around bugs in the browsers themselves. These hacks understandably cause CSS validators to complain that they are invalid. In a couple places, we also use bleeding-edge CSS features that aren’t yet fully standardized, but these are used purely for progressive enhancement.
These validation warnings don’t matter in practice since the non-hacky portion of our CSS does fully validate and the hacky portions don’t interfere with the proper functioning of the non-hacky portion, hence why we deliberately ignore these particular warnings.
