Video: An overview of CSS3 capabilities

Now that we've got a better understanding of what CSS3 is, let's take a moment to explore what it can do. I want to examine the features and capabilities that we're going to add to our Explore California test site. Now, first we'll explore the new selectors available to us in CSS3 that gives us much more control over targeting and styling elements on our page. Here for example, we'll add alternating row colors to our tables without using classes or extra markup. Next we'll examine the new color formats in CSS3 and how the new Color module allows us to control transparency within the browser.

An overview of CSS3 capabilities

Now that we've got a better understanding of what CSS3 is, let's take a moment to explore what it can do. I want to examine the features and capabilities that we're going to add to our Explore California test site. Now, first we'll explore the new selectors available to us in CSS3 that gives us much more control over targeting and styling elements on our page. Here for example, we'll add alternating row colors to our tables without using classes or extra markup. Next we'll examine the new color formats in CSS3 and how the new Color module allows us to control transparency within the browser.

Effects like our homepage image here, for example, are no longer images designed to simulate transparency but truly transparent elements within the browser. CSS3 also allows us to define gradient fills and we'll take advantage of that by adding gradient backgrounds that enhance the look and the feel of our site. Typographic capabilities get a huge boost in CSS3 and as you can see allow us to add non-standard fonts to our sites, as well as adding text effects like embossed text or even drop-shadows. We're also able to define multiple column text without having to resort to extra markups and floats.

Something that every designer is going to rejoice over. Although, a bit more experimental than many of the topics we'll cover, page layout is undergoing changes in CSS3 as well. In this title we'll take a look at the new flexible box model and how it might change the way you design your page layout. We'll also dive deeper into the changes to the CSS box model as well by creating rounded corners, working with border images, box shadows, and the very powerful additions to the background property. We'll take a look at using multiple backgrounds as well as the improved capabilities related to positioning and sizing background images and elements.

We'll also be working with CSS3 transitions and transforms and see how they can add interactivity and enhance user experiences without the use of JavaScript. Finally, we'll tackle using media queries to create multiple versions of the same site so that our site looks great whether it's viewed on a huge monitor, a mobile device, or any screen size in between. Now that you've got a taste of what we're going to be doing, I'm sure that you're eager to jump right in. Before we do that, however, let's take a moment to talk about support of CSS3 and how much of it you can use right now.

I'll pick that back up in our next movie.

Q: I'm following along with the video "Transparency in CSS3".  James shows us how to achieve transparency in Internet Explorer by going to Kimili.com and entering a HSLA value to generate code for transparency.

Here that code:

background: transparent;-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#BF0E0C0B,endColorstr=#BF0E0C0B)"; /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#BF0E0C0B,endColorstr=#BF0E0C0B); /* IE6 & 7 */ zoom: 1;

When this code is added to my HTML file it removes transparency on browsers that do in fact support it. So I'm left with NO transparency. Why?
A: The problem is in the filter code. If the IE background is called last, the first "transparent" declaration will remove all previous colors, regardless of browser. To resolve this, place the rule inside a conditional comment for IE or remove the "transparent" declaration at the front of the rule.
