New CSS 3.0 Features That Web Designers Would Love

While the the W3C seem to be taking forever to implement new web standards and seem happy sitting on their butts forever without moving forward. Here are a bunch of CSS 3.0 proposals that Web Designers would go nuts over if ever they are implemented. I give them time till 2999 to implement them, at the rate things are going in the W3C. I saw the original post here on anieto2k blog but since I don’t understand what language it is written in, I decided to translate it. By the way Opera 9.5 has full support for CSS 3.0

Multi Columns

Currently when you create a multi columned layout i.e 2 column or 3 column layout you need to specify individual and separate DIV HTML elements to achieve the desired effect. But in CSS 3.0 you can achieve this with a single CSS declaration like this

DIV {width: 400px;column-count: 4;
column-width: 100px;
column-gap: 10px;column-rule: none;
}

This is actually possible in FireFox but it is not Standard CSS 3.0 you’ll need to use FireFox Specify code in your CSS to achieve the effect. Example is given below.

-moz-column-count: 3;
-moz-column-gap: 1em;
-webkit-column-count: 3;
-webkit-column-gap: 1em;

Multi-Background

Currently it is not possible to put multiple background Images to the same HTML element but in CSS 3.0 you can easily do this.

background: url('http://www.clazh.com/images/body-top.gif')
top left no-repeat,
url('http://www.clazh.com/images/banner_fresco.jpg')
top 11px no-repeat,
url('http://www.clazh.com/images/body-bottom.gif')
bottom left no-repeat,
url('http://www.clazh.com/images/body-middle.gif')
left repeat-y;

Zebra Tables

You can easily do zebra table without the need for JavaScript or putting CSS Classes on individual Table Rows to give alternate colours.

tr:nth-child(2n+1) /* represents every odd row of a HTML table */;
tr:nth-child(odd)  /* same */
tr:nth-child(2n)   /* represents every even row of a HTML table */
tr:nth-child(even) /* same *//* Alternate paragraph colours in CSS */
p:nth-child(4n+1) { color: navy; }
p:nth-child(4n+2) { color: green; }
p:nth-child(4n+3) { color: maroon; }
p:nth-child(4n+4) { color: purple; }

Rounded Corners

How about the ability to render the ever popular and so called Web 2.0 rounded Corners for a box(html Element) with just a single line of CSS.

Opacity

Currently almost all browsers support their own version and syntax for opacity. Here is the CSS 3.0 Standard code for opacity
