I will clarify my question: When creating a website in modern trends of web development, what standard values do you think you need to write to the CSS file, so to say, template, for example, resetting padding and margin, etc. For example, if I am going to create a website with adaptability, then what values should I write to an empty css file at the very beginning of work? I understand that there are different tasks and, accordingly, different approaches, but I am interested in your opinion. In other words: what does your css template look like?
