While it is very exciting to code using raw HTML and CSS, Bootstrap has changed it a lot. Fanboys may not like it, but it is what happened in the last decade. Creating a website got as easy as cut and paste.
This change didn't go unnoticed. A lot of similar frameworks came into existence. Some said they are more rich and colourful than Bootstrap. Some leaned on we are very light slogan and so on.
But as a web developer, have you ever tried any other Bootstrap framework for production ? How did it go ?
