Changing text size of nested submenu items

Hi guys, I just needed help figuring out how to change the text size of a nested submenu item, I’ve tried .header__submenu .header__menu-item { font-size: 15px; } and that didn’t work so I was wondering if anyone had any ideas of how to change the test size

My website is recreation-creation.com

password is admin

I’ve attached a photo to show where I want the change

Hello There,

  1. In your Shopify Admin go to online store > themes > actions > edit code
  2. Find Asset > base.css and paste this at the bottom of the file:
ul#HeaderMenu-MenuList-3 .header__menu-item {
font-size: 15px!important;
}
ul#HeaderMenu-MenuList-4 .header__menu-item {
font-size: 15px!important;
}
