CSSJanus

Convert CSS stylesheets between left-to-right and right-to-left. This is a PHP port of CSSJanus (written in Python).

Basic usage

$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.

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