Using some new HTML5 tags

HTML has a lot of lesser used, but no less important, tags that are slowly becoming more important as the Semantic Web starts rolling in. These include the , , , , and Because these tags can be a bit hard to figure out, I'll walk you through them so you can see how they're used. We'll start with the tag. The tag used to be used just to make things smaller, but now it has a specific purpose. The tag wraps legalese or fine print content--things like terms and conditions, rules, legal disclaimers, and so on.

I like to use it in my footers to wrap things like the copyright statement in the bottom of the page, so that it's easier to see that this is a copyright statement. Here is an example of how you'd use it. You simply put it in the tag, write in the fine print you want to use there and then end the tag. The next tag is . Now, used to be used a lot, and then people stopped using it, and now it's back. The tag is now supposed to wrap the title of work pointing to another source. So for example, if you put in a blockquote with a quote from a different source, then you would put them in a cite quote, with the name of that source, and then within that, put an anchor tag that points out to the source so people can click on it, and go to that source.

An example of using the is this. Because I got this information from the W3C Web Standards website, I'll wrap W3C Web Standards in a cite tag so that it is clear where it came from. The tag is a new tag that has a lot of potential. It's not really being used much now, but it will be in the future, and you'll see why in a second. The meter tag measures data within a certain range, for instance, "9 out of 10 lynda.com viewers are human," or 80% or something like that.

The point of the tag is that it actually carries with it information about the number within the tag itself. If you look at an example, you'll see what I mean. When you add the tag, you also add attributes. In this case, when you say 9 out of 10, we add the value ="9" and then we set the minimum="0" and the max="10". Now we can use CSS in JavaScript to display a scale from 0 to 10, and then point out the 9 value on that scale. You can also use it to show something like 90% out of a 100, by marking it up this way. Meter value=0.9, which is 90%, and again, you can use CSS to then show a scale from 0 to 100, and mark off to 90% mark.

The tag is the abbreviation tag. You use it to wrap acronyms and abbreviations. The purpose of this tag is to provide extra information, because if you use an acronym or an abbreviation, chances are the person reading it won't know what these mean, and here's a good example. If you see the abbreviation c-o-l or col dot, you don't know what that means. It could either be colonial, it could be colonel, it could be could be college, or it could be something else. But by wrapping this in the tag and adding a title, if you then move your mouse and hover over the abbreviation, you'll see a little pop-up that gives you the full explanation of what that word means.

Finally, we have the In fact, the week before we recorded this course, the W3C who decide these things, what tags people can or cannot use, decided to pull the the HTML5 standard, only to reintroduce it because developers got so angry. The idea with the can tell the browser what time this is, and then the browser can do something with it. The way you mark that up is by saying time and then datetime and then you can either mark it up by a standard 24-hour clock, so 9:30 p.m. will become 21:30, or you can even attach a specific time on the Gregorian calendar.

In this case I've added a datetime that points to Winter Solstice 2011, which is on the 22nd of December at 5:30 a.m. in England. You'll notice it says +00:00 at the end. That refers to the zero timeline. So if you wanted to refer to a time, for instance in LA, you would say +08:00, because it's eight hours ahead. The once you add the Web app that would pick up the time and either change it depending on where the person who's visiting the site is, or add that time to your calendar, add it to some other elements where you can use it actively, and that's the whole point of all these tags.

As the Web progresses and browsers progress, we can build-in new functions that hook into the tags and pull out information of the website, in addition to what you've written. Using the correct markup in your copy can add a lot of information to the material that's already there. That's the whole point of hypertext, to add new layers of information that's not available in print.
