Even though CSS3 is not fully supported yet, many web developers are starting to use many of the new techniques introduced. CSS3 has taken a very large step forward in helping web developers get away from importing mass amounts of images/JavaScript and making it possible to do this only by using pure CSS. I am going to go over 10 CSS3 features you will love to start using!

Border Radius
The ability to have rounded corners without images and JavaScript is one of the most sought after features of CSS3. Having to make images for each corner or importing a new library just to get the nice round edge will be a thing of the past with CSS3 Border Radius. With CSS3, we can do this with only a few lines of code:

view sourceprint?
1 #my_id { 

2     height: 100px; 

3     width: 100px; 

4     border:  1px solid #FFF; 

5     /* For Mozilla: */

6     -moz-border-radius: 15px; 

7     /* For WebKit: */

8     -webkit-border-radius: 15px; 

9 }
Border Images
This is one of my favorite upcoming features, having border images will allow developers and designers to take there site to the next level. You can be as creative as you want and be able to apply it as a border without extra elements. Quite simple code really:

view sourceprint?
1 #my_id { 

2     /* url, top image, right image, bottom image, left image */

3     border-image:  url(border.png) 30 30 30 30 round round; 

4 }
Box Shadow
Before CSS3, we had to either use a shadow image or JavaScript to apply a shadow or create the shadow directly in the image. Neither of those are fun to do in any way. With CSS3 Box Shadow we can apply shadows to almost every element of our website. Here is how:

view sourceprint?
1 #my_id { 

2     background: #FFF; 

3     border: 1px solid #000; 

4     /* For Mozilla: */

5     -moz-box-shadow: 5px #999; 

6     /* For WebKit: */

7     -webkit-box-shadow: 5px #999; 

8 }
Multi-Column Layout
Another CSS3 feature that developers, including myself are very eager to start using is the Multi-Column Layout. It offers a new way to arrange text in more of a “news paper” type way. You have the choice to pick the amount of columns, the column width, column gap width, and column separator. A feature like this was not possible before CSS3. Here is how you do it:

view sourceprint?
01 #my_id { 

02     text-size: 12px; 

03     /* For Mozilla: */

04     -moz-column-gap: 1em; 

05     -moz-column-rule: 1px solid #000; 

06     -moz-column-count: 3; 

07     /* For WebKit: */

08     -webkit-column-gap: 1em; 

09     -webkitcolumn-rule: 1px solid #000; 

10     -webkit-column-count: 3; 

11 }
*Note: column-space-distribution is not implemented yet, this feature is to describe how to distribute leftover space.

Multiple Backgrounds
In the past, having layered backgrounds required you to create more than one element. But now, with CSS3 you can have multiple backgrounds on a single element. This will eliminate a huge annoyance that we have had to deal with in the past. Here’s how it works:

view sourceprint?
1 #my_id { 

2     background: 

3         url(topbg.jpg) top left no-repeat, 

4         url(middlebg.jpg)center left no-repeat, 

5         url(bottombg.jpg) bottom left no-repeat; 

6 }
Now, this feature is not entirely new to CSS3, it is supported in CSS2 and has been in implemented in IE since version 5, however that implementation relied on Embedded Open Type. The new CSS3 implementation will allow developers and designers to use any licensed TrueType “.tff” or OpenType “.otf” ” in their web designs. Here is how to use the custom fonts:

view sourceprint?
1 @font-face { 

2     font-family: “my-font”; 

3     src: url(my-font.tff) format(“truetype”); 

4 }
view sourceprint?
1 #my_id { 

2     font-family: “my-font”, sans-serif; 

3 }
Attribute Selectors
In CSS3, three additional attribute selections are available for matching substrings of the attribute value. Here are a few examples on how to use them.

Select elements with title prefix of “t”:

view sourceprint?
1 p[title^=t] { 

2     /* Attributes to give them. */

3 }
Select elements with title suffix of “t”:

view sourceprint?
1 p[title$=t] { 

2     /* Attributes to give them. */

3 }
Select elements with title contain at least one instance of “t”:

view sourceprint?
1 p[title*=t] { 

2     /* Attributes to give them. */

3 }
:nth-child() and :nth-of-type()
The new :nth-child() pseudo-classes is a way to select elements using a formula. The syntax for both is :nth-child(an+b), almost like a linear equation just different variables. The only difference between :nth-child() and :nth-of-type () is that nth-of-type() only considers elements of the given type.

view sourceprint?
1 /* First, Fourth, Seventh, etc.. 

2 /* Any type of element */

3 p:nth-child(3n+1) { 

4     background: #F00; 

5 }
view sourceprint?
1 /* First, Fourth, Seventh, etc.. 

2 /* Only li elements */

3 p li:nth-of-type(3n+1) { 

4     background: #F00; 

5 }
Probably the favorite feature to come in CSS3 is opacity. It is also probably the most already used CSS3 feature as well. There have been ways to use opacity in the past with IE hacks and other methods but the new CSS3 property will allow it to me done much easier. Here’s the code:

view sourceprint?
1 #my_id { 

2     background: #F00; 

3     opacity:  0.5; 

4 }
RGBA Colors
This new feature ties in with opacity, with CSS3 there is RGB and also RGBA. Now hopefully you know that RGB stands for “red, green, blue”. The “a” in RGBA stands for alpha (also known as opacity). This will make a lot of code shortened by tying in that extra property into an existing one.

view sourceprint?
1 #my_id { 

2     background: rgba(255, 212, 45, 0.5); 

Here are a list of examples and uses of css3 by Webdesignerwall and catwhocode

CSS3 As Enhancement

Emboss-Looking Text

Notice how Analog use a 1 pixel text shadow to make the text look embossed? The image in the green circle is captured with a text-shadow supported browser and the image in the red circle is captured with a unsupported browser.


Subtle Rounded Corners and Shadow

Colly uses border-radius and box-shadow to beautify the layout boxes with rounded corners and subtle shadow. If CSS3 is not supported, it will show rectangle boxes which you can barely notice the difference.


Rolling DVDs

This site uses the webkit-transform property to make the DVD roll out on mouseover. Users with a webkit browser such as Safari or Chrome will see the spinning animation. Users with Firefox will see the disc pop out. Users with browser that doesn’t support this feature will see the static DVD image.


Fading Transition

To see this effect: scroll down until the top search bar overlap the content, hover over the top bar, and you will see the semi-transparent background slowly fade into opaque (see it with a webkit browser).


Rounded Corners

Users with a border-radius supported browser will see rounded corners on the Future of Web Design site.


Subtle Text Shadow

SquareSpace enhances their blog title by appling a light shadow which you can barely notice.


When Should You Use CSS3?

No: Rotating Images With CSS3

Be careful if you are applying border on rotated images. The border may cause jittering result.


Yes: Export Rotated Image Instead

To avoid the jittering effect, use Photoshop to rotate the image first and then apply the CSS transformation as seen on the Chirp site.


Yes: Rotating One Large Image

The rotating earth image is a very nice touch on the 404 page of FOWD (see it with a webkit browser).


No: Rotating Multiple Large Images

However, don’t go crazy with rotating multiple large images because it might look choppy.


No: Relying on CSS3

Everything looks fine if you are viewing Ryan Merrill’s site with a webkit browser. But check it again with a different browser such as Flock. Wow, what happened? Everything breaks down. The font is not displaying right and the call to action box disappeared. So, be very careful if you are relying on HTML5 and CSS3 to do your layout.


Yes: Find Fonts With Similar Width as Alternatives

If you are using custom fonts, don’t forget to include web-safe fonts with similar width as alternatives. Bobulate is a good example. She uses Georgia as her alternative font which has similar width and x-height of the custom font Skolar.
