Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@material/rtl) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

RTL

UIs for languages that are read from right-to-left (RTL), such as Arabic and Hebrew, should be mirrored to ensure content is easy to understand.

Usage

Sass Mixins

rtl is the most flexible mixin, because it can work with multiple CSS properties. All other RTL mixins logic could be engineered by only using rtl, but we provide these mixins for convenience.

Both reflexive-property and reflexive-box work with one base box-model property, e.g. margin, border, padding. But reflexive-property is more flexible because it accepts different left and right values. reflexive-box assumes the left and right values are the same, and therefore that the box-model is symmetrical.

reflexive-position is the least flexible mixin. It only works with one horizontal position property, "left" or "right". It also assumes the left and right values are the same.

Mixin	Description
`rtl($root-selector)`	Creates a rule that is applied when the root element is within an RTL context
`reflexive-box($base-property, $default-direction, $value, $root-selector)`	Applies the value to the `#{$base-property}-#{$default-direction}` property in a LTR context, and flips the direction in an RTL context. This mixin zeros out the original value in an RTL context.
`reflexive-property($base-property, $left-value, $right-value, $root-selector)`	Emits rules that assign `#{$base-property}`-left to `#{left-value}` and `#{base-property}`-right to `#{right-value}` in a LTR context, and vice versa in a RTL context. Basically it flips values between a LTR and RTL context.
`reflexive-position($position-property, $value, $root-selector)`	Applies the value to the specified position in a LTR context, and flips the direction in an RTL context. `$position-property` is a horizontal position, either "left" or "right".
`reflexive($left-property, $left-value, $right-property, $right-value, $root-selector)`	Applies the pair of property values to the specified position in a LTR context, and flips the direction in an RTL context.

A note about [dir="rtl"]: rtl($root-selector) checks for [dir="rtl"] on the ancestor element. This works in most cases, it will sometimes lead to false negatives for more complex layouts, e.g.

<html dir="rtl">
  <!-- ... -->
  <div dir="ltr">
    <div class="mdc-foo">Styled incorrectly as RTL!</div>
  </div>
</html>

Unfortunately, we've found that this is the best we can do for now. In the future, selectors such as :dir will help us mitigate this.
