hi, I have a textarea field called episode_explanation and this is in a repeater. What I want to do is I can assign a css class to this field to define the style for the frontend with the following function.php file or in a different way.
With “frontend” you mean the public facing website? Or the admin area? Because all the text field does in the templates is output the text, so, if you need a class you need to wrap the output with an element:
<div class="example"><?php the_sub_field('episode_explanation'); ?></div>
And if you need a unique identifier you can use get_row_index() and add it as ID or class:
<div class="example" id="ex<?= get_row_index() ?>"><?php the_sub_field('episode_explanation'); ?></div>
