Natura11y includes localization support for the 12 right-to-left (RTL) languages around the world:
Two key HTML attributes affect the localization of an document: direction (dir) and language (lang). Both attributes should be present on the <html> tag.
The dir attribute declares the default text direction. A value of ltr sets a left to right text direction. While a value of rtl sets a right to left text direction.
The lang attribute sets the document’s default language. A value of en sets the language to English.
A document written in Arabic, for example, requires both dir="rtl" and a lang="ar" attributes (Figure 1, line 3).
<!DOCTYPE html>
<html dir="rtl" lang="ar">
<head> ... </head>
<body> ... </body>
</html>Natura11y declares all text alignment, margin, padding, position, and border styles using CSS Logical Properties.
With the aformentioned dir="rtl" attribute present on the html tag, all left and right directional styles flip automatically.

The association between hermit crabs and their shelters has significantly influenced their biology.
Natura11y’s directional icons flip horizontally when the dir="rtl" attribute is present. Consider the following directional icons:
Arrow Left
Double Chevron Left
Checkbox Checked
Confirm
The example below illustrates how an Arabic page flows within the Natura11y Framework:
