Visualizing selectors is helpful. In this video, practice using compound selectors in a sample HTML document in CodePen.
- [Instructor] It's possible to combine selectors … in all kinds of interesting ways. … We'll cover many of these ways in the course, … but the first way I'd like to discuss … is what's called a compound selector. … So if you take a look here at this code pen, … you'll notice over here in our HTML we have both a paragraph … and a unordered list that have a class of myclass. … They both have red text inside of them … in the display down here on the bottom. … What if I only wanted to have the paragraph appear red, … while the ul appeared blue? … So with a CSS class that I have here right now … that's not going to be possible … because anything with a class of myclass will be red. … However, if I go in ahead and put that HTML element … in front of the myclass selector, … in other words let's just say p.myclass, … then only the paragraph will wind up being red in this case. … And that is because this selector is saying that … for all paragraphs that have that class of myclass … do the following things. …
