Hello CHUNGKWU3,Add this code at the bottom of Theme-> edit code-> assets -> theme.scss.liquid
can you share screen shot of code.
I made the changes around "responsive show/hide helper. And I removed your script already. The pages destroyed./*================ Responsive Show/Hide Helper ================*/
That is not script its just simple CSS , You have to add this on bottom of css only.
I have added the script to the bottom, but still negative result.
Here is my expected position. Move the play button upward to the center.
