Renders the HTML meta viewport element.

Usage & Scenarios

Renders the HTML <meta name="viewport" ... /> element. This element ensures proper rendering and touch zooming on mobile devices.

See details on https://getbootstrap.com/docs/4.3/getting-started/introduction/#responsive-meta-tag.

Sample 1: MetaViewport

Place the control inside the head element. It uses Bootstrap API to control zooming and presentation on mobile devices.

The MetaViewport control has the Width property which sets the width of the page.

The InitialScale property is used to set initial zoom level which is applied when the page is first loaded. The MaximumScale property defines maximum zoom level the user can set.

It is also possible to disable zooming at all with the IsUserScalable property.

<!-- Default meta viewport -->
<bs:MetaViewport/>

<!-- Custom meta viewport -->
<bs:MetaViewport Width="320" InitialScale="2" MaximumScale="4" />

<!-- Meta viewport with disabled user scaling -->
<bs:MetaViewport IsUserScalable="false" />
