Woo its 4 Year.
That’s great Bootstrap have successfully completed their 4 year. Firstly Congrat’s from TrickCollab Team to Mark Otto and Jacob Thornton for their first alpha release of Bootstrap 4. An alpha version means bootstrap is under development and available alpha version for testing and debugging. It’s means bootstrap makes lot of many changes in the coming days or months. Before launch final version of bootstrap 4, we pick the important features that change the front end developer future.
There are 6 most important Feature.
• Less Past, Sass Present.
In Bootstrap 3.0 mostly used less Css preprocessor, but In version 4 bootstrap provide more flexibility with Sass, Reason behind it why bootstrap move from less to sass because Sass more favorable by front-end developers. Sass also compiles faster thanks to libsass.
• Use em and rems units Instead of Pixels and percentage.
Older version like bootstrap 1, 2, 3 grid system, font size, padding, margin etc was totally depend on pixels and percentage. In Bootstrap 4 version, all pixels value swapped with rems and ems. It means bootstrap 4 more reliable to make responsive typography.
