When first I started to build the layout of my web pages I was using the Bootstrap grid system without realizing that there is a powerful layout system inside CSS. Styling takes time and not only an hour but probably days and weeks if you are working on a big project and specifically when it is time to work as a freelancer alone. Many frameworks like Bootstrap and libraries have been built to reduce development time and styling time but I think not every time we need to use those frameworks and libraries, an obvious example is CSS GRID LAYOUT SYSTEM. Not only frameworks and libraries get enhanced but languages like HTML, CSS, and JS are getting enhanced.

Many developers at first struggle to find a good place to start learning CSS grid layout, and I think this can be a reason for developers to avoid using the CSS grid and try to use frameworks and libraries. In this ( my first ) writing I tried to look up some great places from the internet to learn and practice CSS grid layout and I found the following 7 places are best, I recommend to anyone to start from first place (basic and simple) and then move on gradually to others in the list
