html5 - Difference between initial scale and user scalable -

-

what difference between initial-scale , user-scalable ? because feel there no difference between them.

initial-scale , user-scalable serve different purposes, , far being same:

  • initial-scale:

    • specifies initial zoom factor window or viewing area.
    • it translates zoom property.
    • internally, values translated numeric values in range [0.1, 10].

  • user-scalable:

    • specifies if user able change zoom factor.
    • it translates user-zoom.
    • internally, values translated zoom or fixed.

so use initial-scale specify how zoomed/scaled page when loads, , use user-scalable specify if user able zoom in/out interacting page.
