CSSJanus

Convert CSS stylesheets between left-to-right and right-to-left.

Basic usage

```php $rtlCss = CSSJanus::transform( $ltrCss ); ```

Advanced usage

transform( $css, $swapLtrRtlInURL = false, $swapLeftRightInURL = false )

  • $css (string) Stylesheet to transform
  • $swapLtrRtlInURL (boolean) Swap 'ltr' and 'rtl' in URLs
  • $swapLeftRightInURL (boolean) Swap 'left' and 'right' in URLs

Preventing flipping

Use a /* @noflip comment to protect a rule from being changed.

```css .rule1 { /* Will be converted to margin-right margin-left: 1em; } /* .rule2 { /* Will be preserved as margin-left margin-left: 1em; } ```

Port

This is a PHP port of the Node.js implementation of CSSJanus.

Feature requests and bugs related to the actual CSS transformation or test cases of it, should be submitted upstream at https://github.com/cssjanus/cssjanus.

Upstream releases will be ported here.
