URL Bar Typing Animation
Three letters type into a browser address bar, the rest of the address appears as a highlighted inline suggestion, then Enter accepts it and a thin loading bar runs along the bottom.
Also known as: address bar autocomplete animation, browser url typing css, inline autocomplete effect.

}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.
