Hello,
It is possible to modify the text and style of the “out of stock product” message on the WooCommerce My Account page.
To change the text, you can use a translation plugin like Loco Translate or WPML to override the default text string. This will allow you to change “out of stock product” to “Out of Stock Product” or any other text that you prefer.
To change the style, you can add custom CSS to your theme or child theme to target the “out of stock product” message and apply styling to it. For example, you could add an icon or change the color and font size of the text. https://www.heb-partnernet.com/
Overall, modifying the “out of stock product” message requires some technical knowledge and understanding of WooCommerce and web development, so you may want to consult a developer or a WooCommerce expert if you need further assistance.
