For almost the last 5 years, I have dedicated myself to working as a freelancer on the Internet. During that time, I have built various types of websites with HTML, CSS, JQuery, React.JS, and several frameworks such as Bootstrap and Foundation, but I prefer to use plain HTML, CSS with SASS (CSS PreProcessor), and Gulp Js to build some simple website; This also causes several reasons for increasing the page loading speed.
Besides, I am also used to developing sites with several popular CMS such as Wordpress and OpenCart.
I also use Jekyll, a static site generator, to develop sites with faster performance.
Each site with each method of making it has a good reason to be used for different purposes.
