[BOOTSTRAP 3] Mobile first or Desktop first?

Question

Bootstrap

I've been typesetting for about 2 years, I've always used my grid. But the other day I realized that it is not perfect.
I did not want to refer to the bootstrap grid) Now I decided. Generated a pure grid.
Now I've run into a problem. What is the best way to type Mobile first or Desktop first?
Personally, I'm used to typesetting DESKTOP FIRST. Mobile FIRST is somehow not familiar to me and I don't understand its benefits?
It’s just that when you make Desktop First, you make up the whole site and then you remake the structure for different media queries, and in MOBILE First it’s the other way around for a mobile phone and then for a PC. Somehow not very convenient.

Answer 1

The main idea in mobile first is that we make a beautiful cripple but as informative as possible (with a minimum of functionality and js) and then we treat a little to desctop`a (Where the maximum functionality and everything flies and shines)! ;)

Answer 2

According to the documentation and examples of bootstrap, it’s mobile first, I also used to make up first for the desktop, then mobile, and almost always had to redo something.

Answer 3

When you type mobile-first, you get less code thanks to min-width : $breakpoint media queries.
I, too, for example, first make up the desktop, and then the mobile. But I always get media queries from mobile to desktop - it turns out mobile-first.
