Reseponsive Bookmark Landing page using Sass

*Bookmark Landing page:

the project was fun but it took more time than expected. but had a great experience. I always do google white building projects. The same goes here. Some concepts I implemented through google. The sassy page looks cool.

In the project, the Design part was not so hard. HTML and sass were the design core. But in the Js I had to go with deep thinking and googling stuff, using the console all the time. I think some of the Js code is not beginner friendly. Although, Js part was fun!

I found the main challenge while making it responsive for all screen sizes. It took me about 4hours and a messy scss folder to make it responsive. According to google and W3schools, one should build a mobile interface first and then make it for desktop. I did the opposite. Overall fun project! I really enjoyed it.

My question to everyone: how do you make a responsive webpage? mobile or Desktop first and why? it'll be very helpful to have a detailed answere
