What methods can I use to identify if the browser my users are using does not have support for Bootstrap 4?

My recent project heavily utilizes the advanced features of Bootstrap 4/CSS, making it incompatible with older browsers still in use by some of my visitors.

How can I effectively identify when a user's browser does not support bootstrap 4 so that I can make necessary adjustments? (I'm seeking assistance with detection rather than redirection)

I have come across solutions for detecting compatibility issues with different frameworks, but nothing specific to bootstrap 4 has worked for me yet.

My tech stack includes JavaScript, PHP7, and Bootstrap 4. If this information is relevant, please let me know.

I've heard of Modernizr, but unsure if it fits my needs. What code should I use for detection?

In case I have to resort to UserAgent (which is unreliable), are there any existing solutions available to avoid starting from scratch?

Appreciate your help!
