Lisebelisoa tse arabelang

All @screen- variables have been removed in v4.0.0. Use the media-breakpoint-up(), media-breakpoint-down(), or media-breakpoint-only() Sass mixins or the $grid-breakpoints Sass map instead.

Our responsive utility classes have largely been removed in favor of explicit display utilities.

• The .hidden and .show classes have been removed because they conflicted with jQuery’s $(...).hide() and $(...).show() methods. Instead, try toggling the [hidden] attribute or use inline styles like style="display: none;" and style="display: block;".
• All .hidden- classes have been removed, save for the print utilities which have been renamed.
  • Removed from v3: .hidden-xs .hidden-sm .hidden-md .hidden-lg .visible-xs-block .visible-xs-inline .visible-xs-inline-block .visible-sm-block .visible-sm-inline .visible-sm-inline-block .visible-md-block .visible-md-inline .visible-md-inline-block .visible-lg-block .visible-lg-inline .visible-lg-inline-block
  • Removed from v4 alphas: .hidden-xs-up .hidden-xs-down .hidden-sm-up .hidden-sm-down .hidden-md-up .hidden-md-down .hidden-lg-up .hidden-lg-down
• Print utilities no longer start with .hidden- or .visible-, but with .d-print-.
  • Old names: .visible-print-block, .visible-print-inline, .visible-print-inline-block, .hidden-print
  • Lihlopha tse ncha: .d-print-block, .d-print-inline, .d-print-inline-block,.d-print-none
