skunka Hi
Unfortunately, Chrome’s Reading Mode only recognizes specific HTML tags to identify the main content. To make it work correctly, you can adjust the article layout slightly.
Open the file: /templates/ja_alpha/html/com_content/article/default.php
Then wrap the main content <div> with a <main> tag, like so:
<main id="main-content">
<div class="com-content-article item-page<?php echo $this->pageclass_sfx; ?>" itemscope itemtype="https://schema.org/Article">
...
</div>
</main>
I’ve also attached the updated file here for your reference:
