Video: Create, nest, and class DIV tags

So in Dreamweaver's HTML file, let's come over to Code view. Now inside of the Code view inside of the body tag, I'm going to hit a few Returns. And as I was mentioning in the last movie, when we start typing inside of code view here, Dreamweaver is going to sort of help us code this, and it's even going to access the CSS rules that we've created. So let's start by creating our very first div. I'm going to type the beginning bracket, div, and hit space and type cl for class. Notice how this pop-up window is coming up and giving me access to everything that is available, either in HTML or in the CSS that's hooked in.

In Create an Interactive Photo Gallery with jQuery and Dreamweaver, author Chris Converse develops an interactive photo gallery for a web site using HTML, CSS, and the open-source JavaScript library jQuery. The course begins with tutorials on extracting different-sized images sets from an original photo collection, designing the site layout, and constructing the HTML and CSS. Then, following the progressive enhancement strategy, Chris utilizes JavaScript plug-ins to include lightboxes and other types of interactivity while maintaining backwards compatibility with older browsers and devices. Exercise files accompany the course.

Topics include:
  • Preparing gallery photos using Adobe Bridge
  • Adding and linking thumbnail images
  • Creating the layout in HTML and CSS
  • Downloading and adding jQuery to the project

  • Implementing the preload functionality
  • Building a customized lightbox with the Fancybox plug-in
  • Styling the zoom and contact links

Create, nest, and class DIV tags

So in Dreamweaver's HTML file, let's come over to Code view. Now inside of the Code view inside of the body tag, I'm going to hit a few Returns. And as I was mentioning in the last movie, when we start typing inside of code view here, Dreamweaver is going to sort of help us code this, and it's even going to access the CSS rules that we've created. So let's start by creating our very first div. I'm going to type the beginning bracket, div, and hit space and type cl for class. Notice how this pop-up window is coming up and giving me access to everything that is available, either in HTML or in the CSS that's hooked in.

So I am going to hit Return to type class, and then I see a dynamic listing of all of the classes I've created in my CSS document. I can use my arrow key down and come down to page_container. Hit Return. I'm going to hit an ending bracket to close the tag. I'm going to start a new tag hit a forward slash and Dreamweaver will automatically close that div tag for me. Now, I'm going to arrow back and get my cursor in between the beginning and ending div tags. I am going to hit a few Returns. This is going to be the overall container which is going to hold everything in our page.

In the next line, I'm going to hit Tab, and let's create our first nested div. class=, this is going to be the gallery_credit and the tag. And inside of here, I'm just going to add the word text. That way when we switch to Design view, I can actually see where this div is and be able to get inside of it. Hit another Return, another div, class=, this is going to be the gallery_type and the tag, text.

Now in the next line, these two divs are going to have float properties, so we want to clear out the float. class= clear_both. End that tag. Hit Return. Next, we're going to create the gallery_top. End that tag. gallery_content.

Next, we'll create gallery_bottom. Then I'll close out the space on the ending div. So these are all of the main children that we're going to create under the page_container area. So now let's come into gallery_ content and let's open this up, and there is actually going to be children inside of gallery_content. This is going to be the middle area where we're going to have the stretching graphic defined inside the CSS, our tiling graphic we created in Photoshop. And this is going to hold our thumbnails and preview, caption and contact area.

So inside of gallery_content, let's create a new div. This is going to be gallery_thumbnails. Let's end that div. Inside of gallery_thumbnails, let's open that up, and inside, let's type the word link. This is where we're going to put our thumbnail links. These links are actually going to be anchor tags that are going to have block properties assigned, and they are going to have float properties as well. So we're going to need to clear those.

So we'll add our clear_both to clear all those, our float and anchor tags, once we have them in place. Let's come on the line after gallery_ thumbnails. Let's create a new div. This is going to be our gallery_preview. Let's end that. Let's open up gallery_preview, and inside there, let's just type the word img. Let's scroll down here a little bit. Now gallery_thumbnails and gallery_preview are going to be classes that are also going to float, so they're next to each other.

Let's add a clear_both to clear the float on those two properties. Next, we're going to type gallery_ contact. This is going to contain our email address on the left side underneath all of the thumbnails. Let's create a new tag. This is going to be the caption. This is going to be floating on the right-hand side under the preview.

Let's end that tag. Inside of each of these, let's just type the word 'text' so we can see them. Now these two items are also going to be floating, so let's clear those. Now, on the next line, we're going to add one more div, class= gallery_preload_area.

Now, this particular class name doesn't exist in our CSS rules; however, we are going to log on to this class using jQuery, and this is where we're going to preload our images. Just like we saw in the introduction video, when we click a thumbnail, we will load an image into this area, preload it, and then when it's ready, we'll move the HTML to the main preview area and then fade up our content. So with this, this is the entire div structure and the order that we need to have all of our classes nested inside of each other to recreate our layout.

Now in the next movie, we'll go back into our CSS rules and start to assign our graphics and styling for each one of these items.

Q: The finished state of the interactive photo gallery in this course shows a clickable preview. When you click on the preview image, or on the view larger icon, a larger lightbox image appears. Chris's example has a close button and border surronding the large image, but mine doesn't. Did I miss a step?
A: The functionality you describe is part of FancyBox plug-in we use in this course. It's a custom lightbox tool, which I've included in the exercise files and also available for download at fancybox.net. It's free and highly customizable.
 
By default, FancyBox adds a border to images (at least in the version of FancyBox we're using), but there are many options that can be turned on when you set up your fancybox initialization script, including the close button, which is invoked using the showCloseButton property. This is all covered in the "Creating a custom function for lightbox properties" movie.
 
If you want to customize your gallery further, look at the list of the customizable properties at http://fancybox.net/api.
Q: This course was updated in April, 2013. What changed?
A: Since the release of this course, Internet Explorer 9 and 10 have been released, and sometimes these browsers do not activate interactive HTML content. To remedy this problem, the author has added a movie to Chapter 10 that will show you how to:
- Update the HTML to HTML5
- Update the version of jQuery
- Use the Google html5shiv to keep compatibility with Internet Explorer 7 & 8
