API
Functions
Right-to-left uses the following low-level functions to implement its right-to-left support.
extract-1-to-4-values($one, $two: null, $three: null, $four: null)
Returns a Sass List containing four values conforming to CSS specifications regarding the number of arguments of 1-to-4 declarations: if it is passed four values, they are returned as-it; if
$four
is missing, it is the same as$two
; if$three
is missing, it is the same as$one
; if$two
is missing, it is the same as$one
.
Mixins
Right-to-left uses the following low-level mixins to implement its right-to-left support. Feel free to use them to provide right-to-left support to declarations that are not (yet ^^) supported by rtl-sass.
declaration($property, $leftToRightValue, $rightToLeftValue)
The lowest-level API mixin, called by all other mixins of the rtl-sass API. Provides right-to-left support by explicitly passing ltr and rtl values.
To mimic the hypothetical CSS declaration...
[dir="ltr"] .dummy { dummy-property: left-to-right-value; } [dir="rtl"] .dummy { dummy-property: right-to-left-value; }
...this mixin would be called with the following form:
@include declaration(dummy-property, left-to-right-value, right-to-left-value);
declaration-1-to-4($property, $top, $right: null, $bottom: null, $left: null)
Used to provide right-to-left support for side-related declarations using 1-to-4 value syntax - for example
margin: 20px 10px
. This mixin conforms to CSS specifications regarding the number of arguments: if it is passed four values, they set top, right, bottom and left in that order; if$left
is missing, it is the same as$right
; if$bottom
is missing, it is the same as$top
; if$right
is missing, it is the same as$top
.$property
can be either a Sass String or a Sass List. In the latter case, the first element of the list is considered as the property prefix and the second one (if any) as the property suffix. Any additional element of the list is ignored.To add right-to-left support for the hypothetical CSS declaration
dummy: 20px 10px 5px 0px
, this mixin would be called with one of the following forms:@include declaration-1-to-4(dummy, 20px, 10px, 5px, 0px);
@include declaration-1-to-4((dummy), 20px, 10px, 5px, 0px);
...and would compile into:
.test { dummy-top: 20px; dummy-bottom: 5px; } [dir=ltr] .test { dummy-right: 10px; dummy-left: 0; } [dir=rtl] .test { dummy-right: 0; dummy-left: 10px; }
To add right-to-left support for the hypothetical CSS declaration
dummy-width: 20px 10px 5px 0px
, this mixin would be called with the following form...@include declaration-1-to-4((dummy, width), 20px, 10px, 5px, 0px);
...and would compile into:
.test { dummy-top-width: 20px; dummy-bottom-width: 5px; } [dir=ltr] .test { dummy-right-width: 10px; dummy-left-width: 0; } [dir=rtl] .test { dummy-right-width: 0; dummy-left-width: 10px; }
declaration-1-to-4-corner($property, $topLeft, $topRight: null, $bottomRight: null, $bottomLeft: null)
Used to provide right-to-left support for corner-related declarations using 1-to-4 value syntax - for example
radius: 20px 10px
. This mixin conforms to CSS specifications regarding the number of arguments: if it is passed four values, they set top-left, top-right, bottom-right and bottom-left in that order; if$bottomLeft
is omitted it is the same as$topRight
; if$bottomRight
is omitted it is the same as$topLeft
; if$topRight
is omitted it is the same as$topLeft
.$property
can be either a Sass String or a Sass List. In the latter case, the first element of the list is considered as the property prefix and the second one (if any) as the property suffix. Any additional element of the list is ignored.To add right-to-left support for the hypothetical CSS declaration
dummy: 20px 10px 5px 0px
, this mixin would be called with one of the following forms:@include declaration-1-to-4-corner(dummy, 20px, 10px, 5px, 0px);
@include declaration-1-to-4-corner((dummy), 20px, 10px, 5px, 0px);
...and would compile into:
[dir=ltr] .test { dummy-top-left: 20px; dummy-top-right: 10px; dummy-bottom-right: 5px; dummy-bottom-left: 0; } [dir=rtl] .test { dummy-top-left: 10px; dummy-top-right: 20px; dummy-bottom-right: 0; dummy-bottom-left: 5px; }
To add right-to-left support for the hypothetical CSS declaration
dummy-radius: 20px 10px 5px 0px
, this mixin would be called with the following form...@include declaration-1-to-4-corner((dummy, radius), 20px, 10px, 5px, 0px);
...and would compile into:
[dir=ltr] .test { dummy-top-left-radius: 20px; dummy-top-right-radius: 10px; dummy-bottom-right-radius: 5px; dummy-bottom-left-radius: 0; } [dir=rtl] .test { dummy-top-left-radius: 10px; dummy-top-right-radius: 20px; dummy-bottom-right-radius: 0; dummy-bottom-left-radius: 5px; }
declaration-value($property, $value)
Used to provide right-to-left support for declarations where the position is the value of the property - for example
text-align: left
.To add right-to-left support for the hypothetical CSS declaration
dummy: left
, this mixin would be called with the following form:@include declaration-value(dummy, left);
How to use
First, install rtl-sass:
npm i rtl-sass
Then use the module:
@use "{relative/path/to/node_modules}/rtl-sass" as Rtl;
.foo {
Rtl.border-color(orangered);
}
You can also use each module independently:
@use "{relative/path/to/node_modules}/rtl-sass/api" as Api;
@use "{relative/path/to/node_modules}/rtl-sass/border" as Border;
.foo {
@include Api.declaration(float, left, right);
@include Border.border-color(black);
}
