CSS CSS Layout CSS Media Queries Targeting Media Features

about media queries

In the video, the instructor change the overall css so it works on mobile phone and then use media queries to make it work on larger device

is it a standard practice to have the overall css written in terms of mobile devices then use media queries to adjust layout to larger screen size?

What's being described here is called a "mobile first" approach. Which is when your optimise your design for the smaller devices first and then introduce more complicated layouts as you target your styles for the larger devices (i.e. desktop PC's)

So, it's common practice now in CSS to define some base styles that are common in all devices and then introduce and/or override styles using Media Queries. Media Queries are how you change the design so it works on multiple devices.
