Bootstrap 5 for IE 11
Bootstrap 5 drops support for Internet Explorer 11, but you can add support back by simply adding a CSS file and a few JavaScript polyfills.
Quick start
- Download the latest release
- Clone the repository
git clone https://github.com/coliff/bootstrap-ie11.git
- Install with npm
npm install bootstrap-ie11
- Install with yarn
yarn add bootstrap-ie11
- Install with Composer
composer require coliff/bootstrap-ie11
Usage
Just add this in the <head>
which will load the CSS and JS - just for IE users.
If you'd prefer to load the bootstrap-ie11 CSS without JavaScript you could use an IE-only media query as follow:
The CSS can be loaded via a CDN:
Splitting the document.write
Method
To enhance the maintainability and readability of your HTML, you can split the document.write
method when adding Bootstrap 5 and necessary polyfills for Internet Explorer 11. Below is an example of how you can split the document.write
method:
Getting local copies of dependencies
For environments where you need local copies of the dependencies, follow these steps to download and reference them locally:
- Bootstrap CSS - download the .css and corresponding .map files
- Bootstrap JS - download the .js and corresponding .map files
- IE11 Custom Properties
- Element QSA Scope
- PolyFill - this seems to load dynamically based on what functionality the browser making the requests is missing, here's what I did as a workaround:
- Open IE11 or Edge in IE11 mode (search "IE mode" in Edge settings to find and enable)
- Copy/paste the URI in the
src
attribute of the<script>
tag into the browser's URI bar and hit enter, the response will be whatever your app would receive - Copy/paste the text on the page and save it to a new file, now you have a local copy
After downloading the dependencies, update your script to reference these local files:
Forcing IE11 Out of Compatibility Mode
If Internet Explorer is running in Compatibility Mode, it'll behave like an earlier version which could prevent bootstrap-ie11 from working properly. To ensure Internet Explorer 11 does not run your site in compatibility mode, add the following meta tag to your page:

Known Issues
- Internet Explorer 11 does not support vertical alignment of flex items when the flex container has a
min-height
. See Flexbugs #3 for more details. - The ie11CustomProperties polyfill currently removes the
!important
from any CSS variables with that set. See ie11CustomProperties issue #62. - SVG images with
.img-fluid
are sometimes disproportionately sized. To fix this, addwidth: 100%;
or.w-100
where necessary. This fix improperly sizes other image formats, so this isn't applied automatically. - There is a slight delay before the ie11CustomProperties polyfill works its magic. Consider adding
body{font-family:"Segoe UI", Arial, sans-serif;}
to your IE11-only style sheet so there isn't a delay in the text displaying. - View a list of known issues at https://github.com/coliff/bootstrap-ie11/issues.
- From Bootstrap 5.2 onwards, CSS custom properties are used extensively which can cause issues with the ie11CustomProperties polyfill.
