understanding inheritance Sharpen your pencil 310 Chapter 8 Solution h1, h2 { font-family: sans-serif; color: gray; } h1 { } p { } border-bottom: 1px solid black; font-family: sans-serif; color: maroon; Just add a font-family property to your paragraph rule in the “lounge.css” file. I’m wondering if that is really the best solution. Why are we specifying the font-family for EACH element? What if someone added a to the page - would we have to then add a rule for that too? Can’t we just tell the whole page to be sans-serif?
It’s time to talk about your inheritance... Did you notice when you added the font-family property to your “p” selector that it also affected the font family of the elements inside the element? Let’s take a closer look: When you added the font-family property to your CSS p selector, it changed the font family of your elements. But it also changed the font family of the two links and the emphasized text. The elements inside the element inherit the font-family style from Just like you can inherit your blue eyes or brown hair from your parents, elements can inherit styles from their parents. In this case, the and elements inherited the fontfamily style from the element, which is their parent element. It makes sense that changing your paragraph style would change the style of the elements in the paragraph, doesn’t it? After all, if it didn’t, you’d have to go in and add CSS rules for every inline element in every paragraph in your whole site... which would definitely be so NOT fun. Let’s take a look at our XHTML tree to see how inheritance works: If we set the font-family of all the elements, here are all the elements that would be affected. The elements, of course, would be styled with the font-family. The element is a child of a paragraph, but it doesn’t have any text, so it’s not affected. html body h1 p p h2 p img a em a getting started with css Not every style is inherited. Just some are, like font-family. Not to mention, errorprone, tedious, and time-consuming. The , , and elements in the two paragraphs inherit the font-family from their parent elements, the elements. you are here 311
