Release v3.1.0

New features

  • Three new templates: Blog, Cover, and Dashboard.
  • #10884: Add .info variant to contextual table classes.
  • #11138: Add contextual styles to list groups.
  • #11162: Add new sizes, .modal-lg and .modal-sm, to modals for quicker settings on modals. Only applies to modals above the small breakpoint.
  • #11193: Add <kbd> element styles to indicate user input via keyboard.
  • #11244: Add .animation() mixins.
  • #11572: Add contextual background-color classes to match our existing text classes. (This also moves both sets of classes to the Helper Classes section of the CSS docs.)
  • #11675: Add .text-justify class to round out the text alignment classes.
  • #11836: Add new form control feedback classes to toggle icons for each validation state. Works on regular forms, horizontal, and inline.

While we originally wanted v3.1 to include RTL support, we decided to hold back on that for some potentially beneficial unreleased tooling. We'll share more on that when we know more, but suffice to say it's been bumped to v3.2.

CSS changes

  • #10951: Add outline: 0 to .modal to prevent a focus outline from appearing in Chrome for Windows.
  • #11107: Add @modal-backdrop-opacity variable for customizable modal backdrop.
  • #11266: Apply a pixel-based line-height that matches the height to date inputs for iOS 7 for proper vertical alignment of text in the form control.
  • #11286: Add @well-border variable.
  • #11302: Refactor the responsive utility classes to cut a few hundred lines of CSS (more context in #11214).
  • #11435: Prevent the double borders between multiple buttons in an input group.
  • #11561: Add float: left; to .form-controls within input groups to prevent IE9 from screwing up placeholder text and select menu arrows.
  • #11588: Scope font-size to only <p> elements in .jumbotrons and remove the super-sized line-height from the base class to avoid interference with sub-components.
  • #11676: Add -webkit-overflow-scrolling: touch; to modals for smooth scrolling on iOS devices.
  • #11744: Clean up some incompatible properties in forms.less: block level inputs no longer receive vertical-align: middle; unless necessary, e.g. in inline forms.
  • #11748: Updated .scale() mixin so that it accepts optional vertical scale as second parameter.
  • #11750: Reverts v3.0.3's refactor to contextual table classes to ensure they work with striped tables.

  • #11741: Don't set @headings-font-family to the same font stack as the <body>; instead, just use inherit for same default CSS.
  • #11786: Nest media queries within print utilities for mixin-friendliness.
  • #11790: With switch to LESS compiler, remove duplicate CSS generated from the nested .clearfix class and mixin by switching to &:extend(.clearfix all).
  • #11801: Use correct variables for grid containers.
  • #11817: Rework input groups to use the font-size: 0; and white-space: nowrap hack for a more durable component with regards to code formatting and custom font size changes.
  • #11829: Add .make-xs-column mixins to complement the recently added extra small predefined grid classes.
  • #11836: Along with the form validation update, we reset some key form and icon styles:
    • All .form-controls within inline forms are set to width: auto; to prevent stacking of .form-label within a .form-group.
    • Removes all select.form-control settings since those are now inherited by the above change
    • Removes the width: 1em; from the Glyphicons because it was virtually impossible to override.
  • #11841: Breadcrumb padding values now use variables.
  • #11859: Restore @dropdown-caret-color variable, but deprecate it.
  • #11861: Add @list-group-active-text-color variable for improved customization on active list group items.
  • #11868: Cleanup modal z-index values in modals.less.

  • #12249: Add and use @modal-md Less variable for uniformity.
  • #12250: Remove print margins per upstream H5BP change, thus deferring to browser defaults, or users' custom values should they set them.

  • #12353: Scope table border reset in panels to first-child rows.
  • #12359: Reset min-width on <fieldset>s so they don't break responsive tables and behave more like standard block level elements.
  • #12406: Upgrade to Normalize v3.
  • #12422: Reset height on select[multiple] in .input-size() mixin.
  • #12424: Given Normalize v3 upgrade, account for change on <figure> element so that we don't cause backward compatibility issues.
  • #12388: Apply a fixed height to .navbar-brand to ensure adding a Glyphicon doesn't increase it's height.

Remote modal content

If you currently use the modal's remote option, be aware this release may break your modals. Yes, this is a breaking change, but it's first and foremost a bug fix one that corrects a rather longstanding and overlooked error. Our apologies for any headaches it may cause, but it's been missed in the last few patch releases.

See the #11933 pull request for details on the code changes.

Deprecations

  • #10370: Deprecated the .pull-right method for aligning dropdown menus. Includes the following changes:
    • Removed an old and unused pair of selectors that didn’t properly target the right-aligned navbar alignment of dropdown menus.
    • Deprecates the .pull-right alignment in favor of a more specific and unique class name.
    • Adds .dropdown-menu-right as the new alignment class. This is then mixin-ed into the .navbar-right.navbar-nav dropdown menus for auto-alignment (keeping the current behavior we have today).
    • Adds new ability to override that auto-alignment though with the new .dropdown-menu-left, which is mixin-ed in the same way to provide the appropriate specificity of an override. This should never need to be used except for within right-aligned .navbar-nav components.
  • #11660: Deprecate small and .small in blockquote citation in favor of footer element.
  • #12398: Deprecate .box-shadow() mixin.

Documentation

  • #10486: Add note about data-toggle dropdown dependency.

    • Dropped grunt-recess for grunt-contrib-less to get the latest version of LESS (v1.5.x) since Recess was still quite behind.
    • Adds CSScomb to take place of Recess's CSS linting. Includes custom .csscomb.json in project root with basically the same property order as Recess.
