elements and matching tags Q: So matching tags don’t have to be on the same line? A: No; remember the browser doesn’t really care about tabs, returns, and most spaces. So, your tags can start and end anywhere on the same line or they can start and end on different lines. Just make sure you start with an opening tag, like , and end with a closing tag, like . Q: Why do the closing tags have that extra “/”? A: That “/” in the closing tag is to help both you and the browser know where a particular piece of structured content ends. Otherwise, the closing tags would look just like the opening tags, right? ? brain power 26 Chapter 1 there are no Dumb Questions Q: I’ve noticed the HTML in some pages doesn’t always match opening tags with closing tags. A: Well, the tags are supposed to match. In general, browsers do a pretty good job of figuring out what you mean if you write incorrect HTML. But, as you’re going to see, these days there are big benefits to writing totally correct HTML. If you’re worried you’ll never be able to write perfect HTML, don’t be; there are plenty of tools to verify your code before you put it on a Web server so the whole world can see it. For now, just get in the habit of always matching your opening tags with closing tags. Q: Well, what about that tag in the lounge example? Did you forget the closing tag? Tags can be a little more interesting than what you’ve seen so far. Here’s the paragraph tag with a little extra added to it. What do you think this does? A smooth, mild blend of coffees from Mexico, Bolivia and Guatemala. A: Wow, sharp eye. There are some elements that use a shorthand notation with only one tag. Keep that in the back of your mind for now and we’ll come back to it in a later chapter. Q: An element is an opening tag + content + closing tag, but can’t you have tags inside other tags? Like the head and body are inside an tag? A: Yes, HTML tags are often “nested” like that. If you think about it, it’s natural for an HTML page to have a body, which contains a paragraph, and so on. So many HTML elements have other HTML elements between their tags. We’ll take a good look at this kind of thing in later chapters, but for now just get your mind noticing how the elements relate to each other in a page.
Exercise Starbuzz Coffee’s Mission 1 2 3 4 To provide all the caffeine that you need to power your life. Just drink it. Write the HTML for the new “mission.html” page here. Type in your HTML using a text editor, and save it as “mission.html” in the same folder as your “index.html” file. Once you’ve done that, open “mission.html” in your browser. Check your work at the end of the chapter before moving on... Oh, I forgot to mention, we need our company mission on a page, too. Grab the mission statement off one of our coffee cups and create another page for it... getting to know html you are here 27
