Right to Left Text (RTL)

Enabling RTL support in Hyvä requires minimal modifications.

Hyvä generally works well with RTL languages, except for static properties like margins and text alignments that need to be adjusted to accommodate a right-to-left layout.

Specifying HTML Text Direction

Before applying RTL styles, ensure the dir attribute is added to the HTML tag alongside the lang attribute.

By adding dir="rtl" or dir="ltr" (the default value) to the HTML tag, the text direction is applied globally to the entire page.

For information on the dir attribute see the developer mozilla docs

Method 1: Static, set by the theme

The simplest approach is to set the dir tag statically using XML via your theme's default_head_blocks.xml file:

<?xml version="1.0"?>
        <attribute name="dir" value="rtl"/>


While some examples recommend adding the dir attribute to the body tag, it is recommended to place it on the html tag along with the lang tag for proper document semantics.

Method 2: Conditionally, based on the store language

To add the dir attribute to the HTML tag conditionally based on the current language, you'll need to create a module with an observer.

Create a module with an etc/frontend/events.xml file:

<?xml version="1.0"?>
    <event name="layout_load_before">

Create the Observer/AddDirSupport.php file in your module:

Code Sample for the Observer AddDirSupport


namespace <VENDOR>\<MODULE>\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Locale\ResolverInterface;
use Magento\Framework\View\Page\Config as PageConfig;

class AddDirSupport implements ObserverInterface
    private $localeResolver;
    private $pageConfig;

    public function __construct(
        ResolverInterface $localeResolver,
        PageConfig $pageConfig
    ) {
        $this->localeResolver = $localeResolver;
        $this->pageConfig = $pageConfig;

     * @inheritDoc
    public function execute(Observer $observer)
        $currentLang = strtolower(substr($this->localeResolver->getLocale(), 0, 2));
        $rtlLanguages = array('ar', 'arc', 'dv', 'fa', 'ha', 'he', 'khw', 'ks', 'ku', 'ps', 'ur', 'yi');
        $isRtl = in_array($currentLang, $rtlLanguages);
            $isRtl ? 'rtl' : 'ltr'

Using RTL Tailwind Utilities

Starting with Tailwind v3.0, you can add specific styles for RTL direction using the rtl modifier.

For example, to add margin to the left and remove margin from the right in RTL: mr-4 rtl:mr-0 rtl:ml-4.

For more details on usage, refer to the Tailwind documentation

Using Direction-Aware Tailwind Utilities

Tailwind v3.3 introduced direction-aware utilities, allowing you to maintain consistent styling across LTR and RTL text directions with less effort.

Instead of using the traditional pl-4 for left padding in RTL, you can simply employ ps-4, which automatically applies pl-4 for LTR and pr-4 for RTL.

This functionality relies on the introduction of new utility classes using s for "start" direction and e for "end" direction.

For instance, instead of using pl-2 for left padding in RTL, you can utilize ps-2, ensuring consistent styling regardless of text direction.

To delve deeper into this feature, refer to the Tailwind v3.3 release blog post:

For those still using an earlier Tailwind version, the Tailwind RTL Plugin: community plugin offers backward compatibility and provides direction-aware utilities.
