Hi @shengwenwen ,

This is Anthony from Beae Landing Page Builder, and I’m happy to assist you today.

While I acknowledge that this issue falls short of the desired outcome, I have an idea that I believe might be of help:

  1. Go to Online Store → Theme → Edit code
  2. Open your theme.liquid file
  3. Paste below code before :

Note: You can adjust value to fit your store

Best regrads,

Anthony

Hello there,

  1. In your Shopify Admin go to online store > themes > actions > edit code
  2. Find Asset > theme.css and paste this at the bottom of the file:
.h2.product-single__title {
font-size: 25px;
}

Hello @shengwenwen :waving_hand:

Inside Shopify Admin, go to Edit theme code, open file base.css and add this code at the bottom

.product-single__title {
    font-size: 32px;
}

Feel free to change the font size value as you need.
