CSS and JS Caching Question

Hey Everyone,

This is my first post and I hope this hasn’t been answered already. In doing some research on here, I’ve realized that my site’s problem is most likely the caching on the server. When I update the CSS on my theme (Bridge), sometimes the changes won’t show for over a day, and after trying everything, that must be the problem.

But my question is different. I want to know if certain parts are cached differently. For example, in Visual Composer, if I change the padding or margin on an element, the change is apparent immediately. However, if I add custom CSS to either APPEARANCE > EDITO or QODE > OPTIONS > CUSTOM CODE, the changes don’t appear until the next day.

Why is this? Why does some CSS not change immediately while other CSS does?

Thanks!
