Do you set device width when designing responsive web applications?
When designing a responsive website, you need to make sure that the browser understands how to correctly render your website. Device-Width informs the browser what the size of the viewport should be.
Since we want our website to render corectly for all screen sizes, we specify that it should set the viewport to the size of the device's screen.
<meta name="viewport" content="width=device-width" />
This ensures the browser always renders at the correct resolution for the device.
