Hey guys, 

I want to change the button to select the size on the product page to the following background color: #202A44 and the font color white. Thank you!

Hi @domo2 ,

Try this one. 

1. From your Shopify admin dashboard, click on "Online Store" and then "Themes".
2. Find the theme that you want to edit and click on "Actions" and then "Edit code".
3. In the "Assets" folder, click on "base.css, style.css or theme.css" file, depending on which file your theme uses to store its CSS styles. At the bottom of the file, add the following CSS code:
4. And Save.

fieldset.js.product-form__input input[type=radio]:checked+label {
    background: #202A44;
    color: white;
}

Result:

I hope it help.

Hi,

Do you know where to add that code in the "symmetry" theme? I can't find "base.css, style.css or theme.css" in the Assets folder.

Best
