five CSS3 Techniques For Major Browsers using the Power of jQuery

Many exciting new functions and features are being thought up for CSS3: text-shadow, box-sizing, opacity, multiple backgrounds, border-radius, border-image, etc…

1. Border Radius: Create rounded corners

W3C has offered a very interesting option for borders in CSS3, of which one is border-radius. This CSS3 styling rule allows rounded corners to be set. Both Mozila/Firefox and Safari 3 have implemented this function, which allows you to create round corners on box-items.

Use the followig css code to replicate the above example.

  1. #rounded-box {
  2. -moz-border-radius-topleft: 15px;
  3. -moz-border-radius-topright: 0px;
  4. -moz-border-radius-bottomright: 15px;
  5. -moz-border-radius-bottomleft: 0px;
  6. -webkit-border-topleft-radius: 15px;
  7. -webkit-border-toprightright-radius: 0px;
  8. -webkit-border-bottomleft-radius: 0px;
  9. -webkit-border-bottomrightright-radius: 15px;

Another exciting new border feature of CSS3 is the property border-image. Border-image, allows an image to be used as the border of an element. Each side of the image corresponds to a side of the HTML object.

jquery.borderImage is a cross-browser, partial implementation of CSS3’s border-image property. This plugin can create the same effect as border-image by creating nine slices from the image one by one, and then tile them in the background of our element.

3. Multiple Backgrounds

CSS3 allows for multiple background images on one element, this is a real time saver. To do this, you can separate backgrounds by commas, like this

  1. #multiple-background-box {
  2. background: url(top-bg.gif) top left no-repeat,
  3. url(bottombottom-bg.gif) bottombottom left no-repeat,
  4. url(middle-bg.gif) left repeat-y;
  5. padding: 20px;
  6. }

Since this features is not supported by most browsers yet, and you want multiple/layered backgrounds for a div tag, you would nest div tags inside of each other with the CSS to give it the background you wanted. That’s a lot of code, and doesn’t seem too effecient. The solution is to use jQuery with the Background Layers plugin.

How To » CSS Multiple Backgrounds / Background Layering with jQuery

The Background Layers plugin reduces the amount XHTML you need to write simply by adding a few lines of JavaScript, making your code much less cumbersome. The concept is similar to the use of layers in Photoshop, one background image on top of another.

  1. <script type=“text/javascript” src=“/includes/jquery.background_layers.js”></script>
  2. <script type=“text/javascript”>
  3. $(function(){
  4. $(‘.marioBox’).add_layer(“#A4D3FF”);
  5. $(‘.marioBox’).add_layer(“url(‘/images/mario_floor.gif’) no-repeat bottom”);
  6. $(‘.marioBox’).add_layer(“url(‘/images/mario_bush.gif’) no-repeat 10px 167px”);
  7. $(‘.marioBox’).add_layer(“url(‘/images/mario_pipe.gif’) no-repeat 180px 183px”);
  8. $(‘.marioBox’).add_layer(“url(‘/images/mario_cloud.gif’) no-repeat 90px 93px”);
  9. $(‘.marioBox’).add_layer(“url(‘/images/mario_cloud.gif’) no-repeat 180px 53px”);
  10. $(‘.marioBox’).add_layer(“url(‘/images/mario_cloud.gif’) no-repeat 20px 73px”);
  11. $(‘.marioBox’).add_layer(“url(‘/images/goomba.gif’) no-repeat 70px 214px”);
  12. $(‘.marioBox’).add_layer(“url(‘/images/mario.gif’) no-repeat 180px 156px”);
  13. });
  14. </script>
  15. <div class=“marioBox” style=“height: 248px; width: 248px;”></div>

4. Box Shadow and Text Shadow

The main goal of this property is to give designers and css coders a nice way to display a shadow behind your text. The property syntax should look like this:

  1. h3 { text-shadow: 2px 2px 2px #333; }

A very useful article i found at Kretschmann’s website, explaing different usage of this property and including different example for using it in a nice way.

Again, this property is not supported by Firefox and IE, so we have to find ourself another way of doing it using jQuery.

An element with opacity value 1.0 will be fully opaque (visible) while an element with opacity value 0.0 will be the complete opposite, invisible. Any value inbetween will determine how opaque (or transparent) the element is. Check out this interesting post by Zen Elements explaining how to use it.

  2. div.L2 { background:#036; opacity:0.4; width:575px; height:20px; }
