Hello,
You can change the font of the My account text by means of the Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class. Please navigate to the Theme Settings > Typography > Advanced Typography.
Here is the documentation providing more detailed instructions: https://xtemos.com/docs/woodmart/advanced-typography-settings/
The background of the shopping cart is set in the Theme Settings > Styles and Colors. Alternatively you can change that by custom CSS:
body .wd-header-cart .wd-tools-icon {
background-color:red!important;
}
Please add the code to the Theme Settings > Custom CSS > General.
Best Regards
