4.0.0-0 (2020-10-30)

⚠ BREAKING CHANGES

The new version overhauls the style definitions of littlefoot elements. This is a breaking change because users will experience visual changes.

Additionally, changes may affect users who have customised their button or popover templates, those who have custom styles applied to footnote elements, or those targetting elements using custom logic.

2.0.0 (2019-06-10)

littlefoot has been rewritten in TypeScript, which enabled a cleaner architecture and slight reduction in bundle size. Browser compatibility is not as extensive as with 1.0.x, and I will no longer support older versions of Internet Explorer.

Testing framework was replaced with Jest and Cypress, and tests were adapted for simplicity.

This version introduces a number of breaking changes to advanced features. If you've been using littlefoot without relying on custom templates or its .activate() and .dismiss() methods, and don't need to provide support for older browsers, it should be safe to upgrade.

Added

  • New .unmount() method to completely remove littlefoot footnotes from the document and return it to its original structure.

Changed

  • Breaking change: .activate() and .dismiss() methods now receive the footnote identifier instead of a selector. The identifier is the sequential ordering of all footnotes in the document, starting from 1.
  • Default contentTemplate and buttonTemplate templates include fewer attributes and improperly-defined custom templates are now less likely to break functionality.
  • Improved pixel size calculations to determine popover height.
  • Improved handling of popover hover state when dismissing.
  • Resolved an issue with the anchorParentSelector element not being hidden (#17).
  • Resolved an issue with inherited font weights and sizes when a footnote was included inside header or <strong> tags (#18).
  • Reduced dependency on DOM element properties for critical functionality.

Removed

  • Breaking change: The .activate() method no longer takes a custom class name to be added to the popover, as the feature is redundant. You can manipulate both the button and the popover upon activation via the activateCallback setting.
  • Breaking change: The footnote-processed class is no longer applied to processed footnotes. Only the footnote-print-only is used now.
  • Breaking change: The is-hover class is no longer applied to hovered footnotes.
  • The purpose of the footnoteParentClass setting ported over from Bigfoot wasn't clear, and it did not appear to change behaviour, so it was removed.

Differences from Bigfoot.js

In forking the Bigfoot.js project and adapting it for simplicity, I have embraced a Decisions, not options philosophy. As such, some features provided by Bigfoot.js have been replaced with simpler alternatives, a sensible set of defaults, and in some cases removed altogether.

Users planning to migrate from Bigfoot should therefore be aware of the following changes.

Settings

Changed settings

  • allowMultipleFN was renamed to allowMultiple.
  • anchorParentTagname was renamed to anchorParentSelector.
  • deleteOnUnhover was renamed to dismissOnUnhover.
  • footnoteTagname was renamed to footnoteSelector.
  • popoverCreateDelay was renamed to activateDelay.
  • popoverDeleteDelay was renamed to dismissDelay.
  • buttonMarkup was replaced with buttonTemplate. Please refer to the documentation for a list of valid tokens.
  • contentMarkup was replaced with contentTemplate. Please refer to the documentation for a list of valid tokens.
  • useFootnoteOnlyOnce was replaced with allowDuplicates. The truth value should be flipped.

Removed settings

  • actionOriginalFN was removed. All original footnotes are only hidden, leaving you free to select footnote DOM elements for removal if you need them gone from the document.
  • breakpoints was removed. All size-aware display changes should be declared via CSS @media queries.
  • footnoteParentClass was removed. After some tests, I couldn't determine its purpose or benefits.
  • maxWidthRelativeTo was removed. It was undocumented and will not be missed.
  • preventPageScroll was removed. Scrolling inside a scrollable footnote will not trigger a page scroll.
  • positionContent was removed. Popover positioning is now always in effect.

Methods

Methods on the returning object were overhauled, removing breakpoint logic.

Changed methods

  • activate() will no longer return a list of activated popovers, it takes a footnote ID instead of a selector, and no longer allows setting a custom class on the popover element through it. Use activateCallback if you wish to manipulate the button or popover elements.
  • close() was renamed dismiss(), it optionally takes a footnote ID instead of a selector, and will no longer return the list of deactivated buttons.

Removed methods

  • addBreakpoint() and removeBreakpoint() were removed, set breakpoint-dependent styles using CSS.
  • The createPopover() alias was removed, use activate().
  • The removePopovers() alias was removed, use dismiss().
  • reposition() and repositionFeet() were removed.

Presentation

All style variants have been folded into a single stylesheet. The footnote popover is now automatically fixed to the bottom of the viewport on smaller screens, and you may alter this behaviour by overriding the CSS.

Breakpoint methods were dropped in favour of a CSS-based approach. Override the stylesheets to customize screen width limits.

The markup for the footnote button ellipsis changed from three <svg> elements with a <circle> each to a single <svg> element containing all three <circle>s.
