<p dir="auto"><a href="https://github.com/openstreetmap/openstreetmap-website/blob/3a534ea895fd60d2c5cccc66251e5472868c0f4e/app/assets/stylesheets/common.scss#L29-L31">https://github.com/openstreetmap/openstreetmap-website/blob/3a534ea895fd60d2c5cccc66251e5472868c0f4e/app/assets/stylesheets/common.scss#L29-L31</a></p>
<p dir="auto">This property then cascades down to every element. Setting dir="auto" on a child element is not enough to override this global text-align. But if we omit the text alignment altogether, everything works fine by default. Having dir=rtl on the body makes everything right-aligned by default, and where we specify dir="auto", then the alignment will automatically flip based on content (since there is no overriding text-align set).</p>
<p dir="auto">Unfortunately bootstrap 4 has <a href="https://github.com/twbs/bootstrap/blob/349a373ff62bf530135ad95d7d1d3f1be6abbf22/scss/_reboot.scss#L53"><code>text-align: left</code> hardcoded</a> and expects RTL-only sites to override this. But in bootstrap 5, which has additional focus on RTL, that was <a href="https://github.com/twbs/bootstrap/pull/28989" data-hovercard-type="pull_request" data-hovercard-url="/twbs/bootstrap/pull/28989/hovercard">removed</a>, and the <a href="https://github.com/twbs/bootstrap/blob/520cc8de92ca48d7ac60102d992d7afe9788b239/scss/_variables.scss#L401">default <code>text-align</code> is now null</a> allowing dir="auto" to work as intended.</p>
<p dir="auto">So fixing this is split into three parts:</p>
<ul dir="auto">
<li>Upgrade to bootstrap 5 (<a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="927086260" data-permission-text="Title is private" data-url="https://github.com/openstreetmap/openstreetmap-website/issues/3230" data-hovercard-type="issue" data-hovercard-url="/openstreetmap/openstreetmap-website/issues/3230/hovercard" href="https://github.com/openstreetmap/openstreetmap-website/issues/3230">#3230</a>).</li>
<li>Remove the global <code>text-align</code> from our own CSS.</li>
<li>Check the other <code>text-align</code> declarations in our CSS, and see which can be removed.</li>
</ul>
