Some More Changes.

  • Glyphicons are not supported in bootstrap 4.
  • Dropdowns can be created using <ul> or <div>. firstly, Dropdowns were made with the help of the <ul> and <li> tag. But now it has provided the ease of developing to the user.

New feature in Bootstrap 4 is:
 New Utility Classes for Spacing: 
a) Bootstrap 3  uses the clearfix just to adjust the floating <div>. 
b) This simply means that it uses  .m-a-0  to  Set all the margins set to zero. Margins are styled by m prefix and padding are styled and use the prefix  p.

 

I hope it will help you understand it quickly.
