Is initial-scale not needed?

Does <meta name="viewport" content="width=device-width"> do the same thing as <meta name="viewport" content="width=device-width, initial-scale=1">?

Hi Megan,

As of February 19, 2021, the MDN article Using the viewport meta tag to control layout on mobile browsers still recommends writing your viewport meta tag as

<meta name="viewport" content="width=device-width, initial-scale=1">

You're using initial-scale=1 to fight the tendency by mobile browsers to automatically zoom out when encountering web layouts, a tendency that dates back to the initial launch of the iPhone. Back then, very few websites were mobile-optimized, so mobile browsers accounted for this by zooming out automatically. This behavior continues today since not all web pages are mobile-friendly.
