Sometimes I see one of these two terms being mentioned when it comes to responsiveness or content adjustment to variations of screen types and devices.
Looking at this documentation in W3S is said to:
Media query is a CSS technique introduced in CSS3. (translating: Media query is a CSS technique presented in CSS3 ).
And Media Rule , where do you get into it? Reinforcing the question: do both terms represent the same thing? If not, what is the difference between them?
