Add `` to the top of the of your page 2. Add the following conditional statements to the `` of your page but after the Bootstrap 4 CSS: ``` ``` #### Optional JavaScript Fix [](#optional-javascript-fix) To fix the dropdown menus and modals you can add the following to the footer: ``` ``` This will load jQuery, PopperJS and Bootstrap as normal on all browsers other than IE8. IE9 will load the `bootstrap-ie9.js` script. IE8 will load the latest compatible version of jQuery, the unminified Bootstrap JS (the minified version causes an error) and the `bootstrap-ie8.js` fix. ### FAQS [](#faqs) **Q. What does this fix/polyfill?** A. Internet Explorer 9 doesn't support flexbox so there is a float-based layout fallback and a couple of other minor fixes. Internet Explorer 8 doesn't support rem units so all units are specified in pixels. Media Queries are also not supported so IE8 has a fixed-width layout (min-width 998px). **Q. Is the CSS hosted on a CDN?** A. Yes, thanks to [JSDelivr](https://www.jsdelivr.com/package/gh/coliff/bootstrap-ie8?path=css) minified versions are available with the direct links: - - **Q. Will you provide LESS/SASS files?** A. Maybe in a future release I'll provide SASS file (with comments). **Q. Do I need the RespondJS polyfill for IE8 like Bootstrap 3 uses?** A. No. Instead the CSS is set to be fixed-width which makes things a lot easier. You don't need to change your HTML markup, the CSS will take care of it as the (min-width:992px) media queries are all set. **Q. Where can I see a demo?** A.
