How to specify class css to override system css

[Dandy Ling Kwong]

I specify my css class for my label in Appery.io editor. However, my css will not take effect as the system css will override my css class, as shown below. How should I do it such that my css class will take effect?

Hello Dandy,

Please try to add code!important/code to your css rules to add them "weight".
