 The `.focus-ring` helper removes the default `outline` on `:focus`, replacing it with a `box-shadow` that can be more broadly customized. The new shadow is made up of a series of CSS variables, inherited from the `:root` level, that can be modified for any element or component.

 The icon link helper component modifies our default link styles to enhance their appearance and quickly align any pairing of icon and text. Alignment is set via inline flexbox styling and a default `gap` value. We stylize the underline with a custom offset and color. Icons are automatically sized to `1em` to best match their associated text's `font-size`.

 Stacks offer a shortcut for applying a number of flexbox properties to quickly and easily create layouts in Bootstrap. All credit for the concept and implementation goes to the open source [Pylon project](https://almonk.github.io/pylon/).

 Bootstrap's default grid system represents the culmination of over a decade of CSS layout techniques, tried and tested by millions of people. But, it was also created without many of the modern CSS features and techniques we're seeing in browsers like the new CSS Grid.

 The `opacity` property sets the opacity level for an element. The opacity level describes the transparency level, where `1` is not transparent at all, `.5` is 50% visible, and `0` is completely transparent.
