Should I use META viewport tag if using only desktop viewports?

Question

As title says, should I use META viewport tag if I'm using only >991px and >1199px media queries in Bootstrap?

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

Answer 1

If you're building your website exclusively for desktop browsing (so no mobile site / responsive site), then no. The viewport tag is only there to tell mobile browsers that you've taken their smaller screens into account.
