Tooltips can greatly improve the usability of your web site by providing direction and cues to visitors. In this course, Chris Converse shows how to convert text or graphics into a mouse-sensitive tooltip. The tutorials demonstrate how to write the necessary HTML and activate the tooltip with jQuery, as well as add positioning and effects.
At this point we're ready to open up our HTML file and start making some changes, so I'm going to open this up in the text editor. Now if you're interested in taking this course in a more visually oriented tool, we're offering the same course in the online training library using Adobe Dreamweaver inside of a text editor. And you can follow along in any text editor or any web editor that gives you access to the source code. Now for those of you who are following along and using this project file instead of your current website, I want to point out some of the things that I've already setup in this file.
First is I've created a hook into the tooltip.css file, so we are actually linking to the CSS file that we're going to be modifying. I've also linked to a copy of jQuery. I've linked to the tooltip.js file. And down here we have an HTML conditional statement which is targeting browsers that are less than IE 9, so this is targeting IE 7 and 8, and we're doing two things here, we're linking to a copy of the HTML5 Google shiv from Google, which takes HTML 5 elements and allows IE 7 and 8 to understand what those are.
And down here you can see we're using things like header, article, and aside. These are all HTML5 tags that IE 7 and 8 don't understand. So this Google shiv will enable IE 7 and 8 to understand that. And then we also have a link to a tooltip_ie.css. This is where we're going to put some custom rules for all of the things that IE 7 and 8 don't understand as part of CSS3. Now the first thing we need to add to our HTML file is a container that's going to hold a tooltip itself. So let's scroll down here in the code, let's find the line for the footer, let's hit a Return, so we are outside of all of our content-containers, but we're still inside of the main div, that's got a class of page.
So inside here we're going to start by typing a div tag, space, we're going to set an id. The name of the id we're going to create is going to be tooltip_container, then let's end the div tag. So the reason we're using an id here is ids are meant to be used once on a page which differs from a class element, which can be used any number of times on your web page. So again, we're going to use an id here just to remind ourselves that this tooltip_container should only appear once in our page.
And now to make this so that we can actually see it in the page to help us with some of our CSS rules, let's temporarily put some text into here. We'll just type this is my tooltip and then hit Save. Now that we've a container for our tooltip. Next, we can work on the CSS styles so that we can define the way the tooltip should look.
