how to show website with full width on mobile devices

Problem

Here is one website which is not responsive but it accommodate full width of mobile screen. http://www.tones.be (try to open on mobile device then you will understand what i mean. it don't have horizontal scroll bar and it is zoom in version of desktop website). I also want to build similar website but unable to figure out how to do so. I know how to use media query for handling screen size. Any suggestion will be helpful.

Solution

Put the meta tag in the head

<head>
    <title>My Website</title>
    <meta name="viewport" content="user-scalable = no">
</head>

You could try to add this in your page head:

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

This will attempt to make the browser display the page at full-width.
