Another way to say that could also be how to make good choices in naming and structuring the various parts of our site. Ultimately, we can think of CSS as operating at two main levels, the browser and the text editor. From the browser's perspective, naming choices don't really matter as long as everything is valid code according to the HTML and CSS specifications. At the level of the editor though, naming an organization matter a lot to the people writing the code. In this case, us. The browser might not care much about repetition and complexity caused by inline styles and poorly named elements, but those who have to edit the code sure will. Along the way, we'll also expand our understanding of what it is that browsers do care about. In Lesson 5, we styled objects using IDs, classes, and by targeting types of elements in general, but now we'll look at how different combinations of those affect what gets rendered by the browser.
