CSS zoom Property

The zoom property is used to scale the content. For scaling the content, you can also use the transform property set to "scale()".

This feature is non-standard and it is not recommended to use it for production sites, because it is not supported by Firefox. Therefore, you can use transform: scale to change a site element’s size.
