Amber Monitor Text
An amber phosphor screen types a command, each fresh letter flaring white-hot then cooling to amber, and the screen fades out slowly with afterglow before the next run. Curved glass and scanlines.
Also known as: amber monitor css, crt effect css, retro terminal text, terminal typing animation.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
