Description

We have 5709 in sequenceserver.min.css. Just learnt this through codeclimate bot in PR #496.

I doubt splitting the CSS for search form and results into two files will help, as I don't think we have 1500+ custom selectors on each page. The bulk is coming from frameworks.

It might help to create multiple CSS bundles: bootstrap, other vendor, custom. Can also check if upgrading frameworks can help minimise the number of selectors.

Contributor guide

Research direction
Investigate the CSS bundling configuration (e.g., Webpack, Rails asset pipeline) and split the CSS into multiple files to avoid the Internet Explorer 4096 selector limit. Consider separating vendor CSS from custom CSS and upgrading frameworks to reduce selector count.
