Writing a website - best practices

Question

Hi, can You recommend any website where I can study how to do things in the right way? For example how to code good header. Yes, I know, id depends. But I think there are basic standards and solutions. It doesn't matter for me how to keep order in code and how html semantic works. This already know. Hope You understand me.
