Start and End in place of Left and Right in Utility Class

To support RTL languages, Bootstrap has renamed the direction properties left and right in favor start and end.

The only breaking change is when you use utility class directly from bootstrap with the class attribute (ie without using for instance the spacing utility for instance).

They have been renamed and we can't do much in this case

The left and right spacing utility have been renamed to support text direction.

• in place of l (left), you get a s (start) - for classes that set margin-left or padding-left in LTR, margin-right or padding-right in RTL
• in place of r (right), you get a e (end)- for classes that set margin-right or padding-right in LTR, margin-left or padding-left in RTL

Theme

The colors have changed in the default Bootstrap them to add more contrast. Unfortunately, it means that the default colors are more bright.

Example with the info color

Deleted

The following elements are deleted in Bootstrap 5 but preserved in Combostrap.

• Card Columns was deleted from Bootstrap 4 but we maintain it as explained in this example
• Jquery is no more a dependency for Bootstrap.
• jumbotron was deleted.

Modified

• The bs namespace has been added to all variables:
  • color names. We maintain the old color scheme without the prefix name by applying the new prefix transparently.
  • data attributes
• auto margin used in the Navgroup with the expand attribute has been renamed from mr-auto to me-auto.
• the assistive technologies class given in the search bar has changed from sr-only to visually-hidden
• badge uses now background class to specify the background color. The colors have changed slightly.
• spacing and Float uses now also the start and end positioning
