CSS3 Transitions

With CSS3, we can add an effect when changing from one style to another, without using Flash animations or JavaScripts.
CSS3 transitions are effects that let an element gradually change from one style to another.

transition: property_name duration timing_function delay;

To do this, you must specify two things:

  • Specify the CSS property you want to add an effect to
  • Specify the duration of the effect

Transition effect on the width property, duration: 2 seconds:

.moduleDefault {
transition: width 2s;
-moz-transition: width 2s; /* Firefox 4 and above */
-webkit-transition: width 2s; /* Safari and Chrome */
-o-transition: width 2s; /* Opera */

Note: If the duration is not specified, the transition will have no effect, because default value is 0.

The effect will start when the specified CSS property changes value. A typical CSS property change would be when a user mouse-over an element:

.moduleDefault:hover {
width: 300px;

Multiple changes:
You can also add a transitional effect for more than one style, add more properties, separated by commas.

Add effects on the width, height, and the transformation:

transition: width 2s, height 2s, transform 2s;
-moz-transition: width 2s, height 2s, -moz-transform 2s;
-webkit-transition: width 2s, height 2s, -webkit-transform 2s;
-o-transition: width 2s, height 2s,-o-transform 2s;

Note: These properties are not supported in IE

CSS3 – Substring matching attribute selectors

[att^=val] : Represents an element with the att attribute whose value begins with the prefix “val”.

[att$=val] : Represents an element with the att attribute whose value ends with the suffix “val”.

[att*=val] : Represents an element with the att attribute whose value contains at least one instance of the substring “val”.

This whole group of selectors is new, and the selectors in it let developers match substrings in the value of an attribute.

Assume that we have an HTML document that contains the following markup structure:
<div id=”nav-primary”></div>
<div id=”content-primary”></div>
<div id=”content-secondary”></div>
<div id=”tertiary-content”></div>
<div id=”nav-secondary”></div>

By using the substring matching attribute selectors we can target combinations of these structural parts of the document.

The following rule will set the background colour of all div elements whose id begins with “nav”:
div[id^=”nav”] { background:#ff0; }

In this case the selector will match div#nav-primary and div#nav-secondary.

To target the div elements whose id ends with “primary”, we could use the following rule:
div[id$=”primary”] { background:#ff0; }

This time the selector will match div#nav-primary and div#content-primary.

The following rule will apply to all div elements whose id contain the substring “content”:
div[id*=”content”] { background:#ff0; }

The elements that will be affected by this rule are div#content-primary, div#content-secondary, and div#tertiary-content.

The substring matching attribute selectors are all fully supported by the latest versions of Mozilla, Chrome, Firefox, Safari and Opera.

Alternative Browsers

Internet Explorer, Firefox and Safari lead the market, but there are other browsers out there for PC and Mac users which can be better then the one you’re using now.

When Microsoft, Mozilla or Apple comes out with a new version of Internet Explorer, Firefox or Safari, it makes news, mainly because most of us use one or more of these three Web browsers. In fact, with the exception of Google’s Chrome (which made a big splash, mostly because it came from Google), most of the alternative browsers out there tend to get lost in the shuffle and it’s too bad, since some of these relatively unknown browsers are good, and could be better for some users than the ones they’re already using.

Check these browsers out; one of them may work for you.

It is an open-source browser based on Mozilla’s Gecko rendering engine, is clearly designed to be a simple, user-friendly, yet fully functional browser. With a look and feel very similar to Safari and Firefox, almost anyone will find it easy to work with in seconds.

It’s got just about every feature built into competing browsers, and many that you won’t find anywhere else, such as a “file sniffer” that makes it easy to download YouTube videos and a popup notepad for pasting or dragging text you want to save. Power users will love it. Those who like sleek design will turn away.

OmniWeb’s best features include extensive ad-blocking, auto-saved Web browsing sessions and site specific preferences. From the unique tab drawer to support for browsing Web pages using OS X’s built-in Speech Recognition, OmniWeb’s hold of Mac specific technologies wrapped in a clean and uncluttered interface makes the product a delightful browser alternative.

Opera 9.6 for Macintosh is a fast, option-laden browser that represents a formidable entry in an extremely competitive product category. Its standout features are Speed Dial startup page, extensive search engine support built into the browser and it also offers support for widgets.

Like Apple’s Safari and Google’s Chrome, Shiira is based on WebKit. One of the first unique interface elements was Shiira’s PageDock which provides the same functionality as tabbed browsing, but with complete thumbnails of every page that is opened. Other features includes the menu items for automatically e-mailing the URL or entire contents of a page with a single click, and a very effective full-screen-mode option that would be perfect for presentations or watching video.

Which is the finest?
It all depends on what you require from a browser!
