How can I apply web-kit to all sections of my website?

[rituraj19csu254]

I am trying to implement web-kit so that my website would work fine on both google and safari after doing a deep research i found that we have to select every time a class for each section to implement web-kit which is not logically correct so i request everyone to give me a solution so that the web-kit is applied on all my section  so that i do not need to work on different different classes each time
