I’ve heard so many people talking about mobile 1st.
From my understanding the idea is that to keep the default CSS rules to the minimum.
And adding more parts and rules in media queries.
Therefore when your site loads on mobile, it will load a lot faster.
The thing that I am still confused with is how do we implement this kind of technique?
So in order to do a mobile 1st site, when I started I just need to resize my browser to mimic a mobile viewport?
Then start from there?
Like in the pic above?
Then what if I want to implement bootstrap into this whole site, when do I add in bootstrap’s elements in it?
From the beginning or after I finished my mobile version of the site 1st, then I add in bootstrap elements ?
If someone is more experienced please leave a comment below about how to efficiently use bootstrap to build a mobile 1st website. And which part of the site I need to create myself and which part of the website I just need to grab from bootstrap’s library. For example: the nav bar, do I go all in and write it myself? Or just grab the ones that are included in bootstrap and only use CSS to change its look.
I’m a newbie, so please be as elaborate as possible. Thanks!
