Font colors and sizes in the shopping cart and checkout

Hello,
I already thought that it could only be changed. Now I have to find out the CSS area so that I know what I have to change.

But I have another big problem.
To change the pages, I tried to create my own pages for products, shopping cart and checkout. I have installed Elementor Pro and did it exactly so as in your description. Create a new layout etc. but it didn’t work. After creating the new layout, only the built -in blocks (Gutenberg) are displayed, none of Elementor or Woodmart. I can’t create my own pages. Does anything have to be set elsewhere so that elementor is made available to me?

In other ways, I can easily create and edit new pages with elementor, only with your WooCommerce Layout Builder it doesn’t work.
I didn’t install WPBackery.

Best regards
Mike

Hello,
super, thanks now it works, but i cannot save my created and edited template, there is a new error message
Update failed. The answer is not a valid JSON answer.
So many problems and error messages, it is probably not that easy if I have no experience.

Hello,
In addition to the plugins that come with Woodmart, I only installed the plugin duplicator and the plugin WooCommerce Custom Product Addons. If I deactivate the plugin WooCommerce Custom Product Addons, this error message no longer seems to come. But that doesn’t make sense for me because I need this plugin. I need additional fields in which customers have to provide information, without these additional fields, the whole shop is worthless for me.
