问题 I'm building an eCommerce website based on Wordpress and Woocommerce. So far everything is going great, but on the last page of the chec-out (billing and shipping), the standard classes of Woocommerce are interfering with the markup of Bootstrap 4.

Anyone knows how to remove these wrapper classes? Thanks a

问题 New to sass I stuck with the problem how to enable the dynamic change of a website theme - lets say a dark and a light theme - through user interaction. The template I use as a base (coreui) has a _custom.scss file in which various variables are defined ... $navbar-bg: #fff; ... The values of these variables would need to be set dynamically depending on the user choice of the theme and I have no clue how to get this done. Any pointer how to implement this would be highly appreciated. 回答1:
