Chapter 8, Problem 1RQ

Program Description Answer

Viewport is the visible area of a webpage for a user . The Meta tag used to configure display for mobile devices is Viewport.

Hence, the correct answer is option “A”.

Explanation of Solution

Tag used to configure mobile devices:

• The webpages designed for computer resolution cannot be viewed the same way on a mobile device.
• Once the viewport tag is configured, the page can be zoomed and scaled to a width that is easy for a user to read.
• The “<meta>” tag is used to let web designers take control over the viewport.

In HTML 5, it can be used as:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Here,

• The “<meta>” gives instructions to the browser to control the page dimension and scaling.
• “width=device-width” is used to set the width of the page similar to the screen width of the mobile device.
• The “initial-scale=1.0” sets the zoom level when the browser loads the page.

Explanation for incorrect options:

Handheld:

Handheld value informs the server that the user has optimized the page and the optimized version can be viewed using a mobile device. It is not used to configure display for mobile devices.

Hence, option “B” is wrong.

Mobile:

There is no mobile tag present in HTML to configure display for mobile devices.

Hence, option “C” is wrong.

Screen:

There is no screen tag present in HTML to configure display for mobile devices.

Hence, option “D” is wrong.
