## Supporting Internet Explorer 8-9
|
||||
|
||||
As of v4, Bootstrap no longer supports IE8 or IE9. **If you require IE8-9 support, we recommend you use Bootstrap 3.** It's still supported by our team for bugfixes and documentation changes, but no new features will be added to it.
|
||||
|
||||
Alternatively, you may add some third party JavaScript to backfill support for IE8-9 to Bootstrap 4. You'll need the following:
|
||||
|
||||
* [The HTML5 shiv](https://en.wikipedia.org/wiki/HTML5_Shiv)
|
||||
* [Respond.js](https://github.com/scottjehl/Respond)
|
||||
* [Rem unit polyfill](https://github.com/chuckcarpenter/REM-unit-polyfill)
|
||||
|
||||
No support will be provided for this, though you may find some help from the community in [our Slack channel]({{ site.slack }}).
|
||||
|
||||
## IE Compatibility modes
|
||||
|
||||
Bootstrap is not supported in the old Internet Explorer compatibility modes. To be sure you're using the latest rendering mode for IE, consider including the appropriate `<meta>` tag in your pages:
|
||||
|
||||
{% highlight html %}
|
||||
<meta http-equiv="X-UA-Compatible" content="IE=edge">
|
||||
{% endhighlight %}
|
||||
|
||||
Confirm the document mode by opening the debugging tools: press <kbd>F12</kbd> and check the "Document Mode".
|
||||
|
||||
This tag is included in all of Bootstrap's documentation and examples to ensure the best rendering possible in each supported version of Internet Explorer.
|
||||
|
||||
See [this StackOverflow question](https://stackoverflow.com/questions/6771258/what-does-meta-http-equiv-x-ua-compatible-content-ie-edge-do) for more information.
|
||||
**If you require IE8-9 support, use Bootstrap 3.** It's the most stable version of our code and is still supported by our team for critical bugfixes and documentation changes. However, no new features will be added to it.
