Hello
I would suggest that in wp-content/themes/basel/seachform.php you change:
<input type="text" placeholder="<?php echo esc_attr_x( 'Search', 'submit button', 'basel' ); ?>" value="<?php echo get_search_query(); ?>" name="s" id="s" />
to:
<input type="text" placeholder="<?php echo esc_attr_x( 'Search for products', 'submit button', 'basel' ); ?>" value="<?php echo get_search_query(); ?>" name="s" id="s" />
to make it consistent with what you have in the Ajax search form 😉 (which is more user friendly).
Regards
