Hello,
For the footer font settings you can use Typography Settings under Theme Settings >> Typography.
You can read our detailed documentation for further help:
https://xtemos.com/docs/woodmart/advanced-typography-settings/
Changing the footer height might affect the view on mobile for the footer.
If you still want the CSS then try adding the following Custom CSS in the Custom CSS for desktop area under Theme Settings.
.container.main-footer {
height: 350px;
}
Best Regards.
.
