> transform-origin specifies the origin of an element's transformation. If only one value is set, the other value is 50%. If both values are set, the first value indicates the position on the x-axis, and the second value indicates the position on the y-axis.
> After the transform attributes are set, the child element changes with the parent element. Value changing of other attributes (such as height and width) of the parent element will not affect the child element.

## Implementing Redirection
To make the launch method of the <button> component take effect, the redirection logic needs to be implemented in the .js file of the page. Call router.push() to add the page URI to the route stack, that is, to jump to the page specified by the URI. You need to import the router module before calling the router method.
