Counter

An animated number that counts up when it scrolls into view — for stats, milestones and results.

The block renders through the counter element — the same PHP that runs in the page builder, so the front end is identical either way.

What the sidebar exposes

Option	What it does
number	The value to count up to
start	The value the count begins at
prefix	Text before the number, e.g. $
suffix	Text after the number, e.g. + or %
decimals	Digits after the decimal point
separator	Insert thousands separators
duration	Animation length in milliseconds
easing	Count-up easing curve
alignment	Horizontal alignment
number_font	Typography for the number
number_color	Number colour

Anything not listed stays available in the page builder, and round-trips untouched — the block only writes the values you change, so an element styled in the builder keeps every setting this sidebar does not show.

The preview shows the final number, not the animation

The canvas preview is deliberately static and shows the target value. Replaying the count-up would reset it to the start value every time the editor scrolled the block into view, which reads as the preview flickering while you work. Visitors see the animation.
