<v ->In lesson five,</v> the first lesson of part two, Learn Enough CSS and Layout to be Dangerous, you'll truly begin to dive into cascading style sheets, the design language of the web. In this lesson, we'll take the first steps on the road to developing a much more complex website style using CSS. We'll start by briefly looking at how CSS developed. And then we'll create a new clean slate page for us to start building on. This will be the index page for our new site. Recall from part one, that the index page is a site's default home page. Next, we'll recap some of the basics of using styles. And then we'll jump right into exploring what the cascading part of cascading style sheets means. And how the styles that you apply to one element spread down to other elements inside. We'll also look at different methods you can use to identify individual, or groups of elements, on the page using class and ID names. If some of this gives you a sense of deja vu from the previous lesson, don't worry. Lesson five approaches the topic of styling from a little more nuanced perspective. And gives us a deeper understanding of how browsers render styles on webpages. Also, this lesson will introduce you to a concept we'll touch on repeatedly throughout this tutorial. Most everything from this point on contains a lot of subjectivity. We don't mean to only say that your site will look different in different browsers and on different devices. And it absolutely will. But also that there's an eternal bog of subjectivity around everything having to do with writing CSS. From ideas about different ways to achieve the same appearance, to different ideas about how to name things. With the tools in part two, you'll learn how to make informed decisions on your own. Welcome to CSS.
