Re: Good or bad practice to hide elements with CSS, as opposed to doing it with jQuery…

Modernizr is a great tool. I use it in all my projects.

This is how html markup looks when JavaScript is OFF:

In your CSS you would target users with JavaScript off, like so `.no-js`.

This is how html markup looks when JavaScript is ON:

The classes that get added depend on what features users browser supports, so you can hook into something like `flexbox` and provide enhanced experience.

You can custom build Modernizr, supporting only features you need. This decreases file size. Modernizr also provides HTML5shiv and many other things.
