css affect on after loaded div content

css affect on after loaded div content

Hi everyone,

I'm new on jquery, so i am stucked and have a question.

I have a main div, it's content is loading with js containing jquery.html function. And also I have a main.css file. After loading this content, some functionalities like onclick or hover does not work. As far as I understand, that after loaded div doesn't get affected from this main.css. How can I fix it or what am I doing wrong?
