resize

Set the Playwright viewport size. Both width and height must be positive integers.

Syntax

When I resize to "<width>" by "<height>"

Qualifier	Role	Example
`to`	Viewport width in pixels	`resize to "375" by "812"`
`by`	Viewport height in pixels	`resize to "375" by "812"`

by here is not a find hint — it pairs with to for height. Find hints use by aria-label / by id / … — see Find hints.

Item	Contract
Element / control shape	None — viewport size
How the label binds	Width `to` and height `by` are positive integer payloads (`by` here is not a find hint)
Qualifiers that change resolve	`to` + `by`
Platform	Web only
Wrong shape → use instead	N/A
