Hello
i have remove the title from the product page and in his place i put the promo text as a second title
is there a way to make it responsive in mobile or change the font-size
design/themes/THEME/templates/blocks/product_templates/default_template.tpl
replace the following part of code
{$product.product nofilter}
Then clear cache
If you are familiar with hooks, use the products:main_info_title hook and My changes module to do it
