Four years have passed after it was introduced, and it still continues to enjoy the popular support of all the companies employing Bootstrap designers.
With version 2 came the responsive design components, and with version 3, Bootstrap has moved to a mobile first approach. On its fourth anniversary, its founders have come out with the Alpha release of Bootstrap 4. So what can be its anticipated? What are its features, up gradations? Let us analyze…
Enhanced Grid system
Right from Bootstrap 3, the grid system has been really wonderful, enabling to design responsive sites effectively and with less effort. Container, row, and column would be the 3 main components of Bootstrap 4 grid system. While the container be utilized for fixed width, container-fluid could be used for full-width rows. Each of the five grid tiers – extra small, small, medium, large, extra large – are to be used based on the minimum width.
More Sass ( Syntactically Awesome Stylesheets)
While, in all its previous versions, Bootstrap has used Less as its preprocessor as a way to compile variables, for the version 4, it uses Sass. Sass is considered to be more powerful and even has a wide developer community. Customization options will henceforth be handled as Sass variables. These options include round-corner angles, transitions, gradients, etc. Using the Bootstrap’s Customizer, it is easy to automate the build process.
An opt-in Flex box support
A new layout mode for CSS – Flexible Boxes is designed for accommodating elements for numerous screen sizes, resolutions, and layouts. Unlike the previous versions of Bootstrap, the version 4.0 offers Flex box as an opt-in ingredient. That said, it needs a CSS recompilation. Flex box support is accessible to the entire grid system and input groups.
Reebot.css: the new reset component
Normalize.css was previously used by Bootstrap as CSS reset. With Bootstrap 4, reset and base styles are clubbed into a single file. Hence, it would be effective to use just reebot.css
Bootstrap 4 version has Glyphicon support withdrawn. In Bootstrap 3, Glyphicons icon font has been handy in adding iconography. There is nothing, however, to replace the withdrawn Glyphicon. Nevertheless, you can replace with MIT-licenced Ionicons through manual integration with Bootstrap.
