Bootstrap 4 has made significant strides in modern web development, but it has unfortunately dropped support for Internet Explorer 8 and 9. However, fear not! With a little bit of clever coding wizardry using conditional statements and polyfills, you can bring Bootstrap 4 back to life for these older browsers. This guide will walk you through the steps you need to follow to set up your project successfully.
Quick Start Options
To integrate Bootstrap 4 into IE8 and IE9, you can choose from several quick start options:
- Download the latest release
- Clone the repository:
git clone https://github.com/coliff/bootstrap-ie8.git - Install with npm:
npm install bootstrap-ie8 - Install with yarn:

composer require coliff/bootstrap-ie8:4.3.1

Next, you’ll want to add conditional statements in your `
` section to include the appropriate CSS files:<!--[if IE 9]>

<script src="https://cdn.jsdelivr.net/g/html5shiv@3.7.3"></script>
