Important Notes

Use ring-offset classes to add space between the element and the ring color.

Outline colors and widths can be combined but may behave differently across browsers.

Rings do not affect layout size, so they won't push other elements away.

Summary

Ring colors add a colored glow around elements without changing layout.

Outline colors create a border-like effect that can be styled with thickness and color.

Use these styles to improve focus visibility and add visual emphasis.
