Why "Mobile First"?

Hi Experts,

I took a CSS course, and was thought that when designing a website with @media breakpoints, start from the smallest (mobile) and work up to tablet, desktop, etc... Is there a specific reason for this?

Personally, I'd prefer the opposite - laying out all my elements on my desktop, then work down to tablet, then finally mobile?

Any feedback will be appreciated.

Mobile screens are the ones that will display the least (and smallest content).

You get it right on mobile and then add extra for desktop.

This is thought to be better than designing for desktop and then trying to take away for mobile.

Basically, getting bigger is easier than getting smaller.

So, this is a matter of preference basically?

It should not have any external affect, like SEO, etc...?

Google gives higher rankings to mobile friendly sites so it is relevant if you are expecting to serve pages to people on mobile devices.

If however you are building a site / application that is going to be used only (or predominantly) by desktop users then obviously this design paradigm does not apply.

Basically, if you need to cater to mobile - then designing for mobile first and scaling up is much easier than doing it the other way around.
