Bootstrap 4 is the newest version of the most popular web framework for developing responsive, mobile-first websites. It’s easy to use and customize with its new grid system, dozens of predefined components, and intuitive Sass variables that allow you to modify all aspects of your site without breaking a sweat. There are some big changes in the latest release (e.g., responsiveness across browsers), but if you’re using an older version like 3 or 2 it might be worth upgrading before any major updates come out. The tradeoffs between these two versions will depend on what kind of website you want to develop – whether it needs more customization options or something simpler like making sure everything works cross-browser (Bootstrap 4). Bootstrap 3 and Bootstrap 4 are different frameworks. The major difference is that bootstrap3 has JavaScript while Bootstrap4 does not. This means the developer must add scripts to their page for it to function properly with Bootstarp3, but this script will be included by default in a new project created using Bootstrapt4 which makes it easier for beginners to use. -Bootstrap 3 lacks many features of newer web development languages such as HTML5 tags or CSS3 properties, so developers need to implement these features manually if they want them on pages built with this framework. Developers have also found that when working with large-scale projects using Bootstrapt3 there’s been an increased chance of errors cropping up due to its reliance on jQuery.
