What is the CSS3

“CSS” is an acronym for Cascading Style Sheets, a web-based markup language used to describe the look and formatting of a website to the browser, most commonly used in HTML or XHTML web pages but also applicable to XML documents, including plain XML, SVG and XUL. “CSS3” simply refers to the latest incarnation of CSS, with additional capabilities far beyond the scope of the first two generations.

CSS3 offers some exciting new features to enhance the appearance of a website. Although these features might not be absolutely necessary to the functionality of a website, users are coming to expect a website to look awesome as well as operate cleanly. CSS3 makes it easier for designs that will make visitors “ooh and aah” over them to be implemented.

Some Use CSS3 Example :

Box-shadows – This could allow the main content to slide beneath another area, such as a footer, or cause the area to look as if it’s coming out of or sinking into the website. CSS3 makes this happen without requiring the coder to create a new image or use a Javascript plugin. Another technique is to cause the shadow to appear upon hover.

Text shadows – Sounds exactly like what it is: provide a drop shadow underneath HTML text elements.

HTML5:Design to Another Level

HTML5 maybe is the latest version of HTML or Hypertext Markup Language. It is currently only fully supported by a handful of browsers but the next year should see a large increase in usage. It isn’t expected to be completed until 2014, but the features that are available now are a great way to become acquainted with HTML5 and add some cool elements to your website.

The idea behind HTML5 is that it’s not one large entity, but rather made up of smaller parts that work together to create something innovative and advanced. Each browser may support different features of HTML5, which makes it important for those interested in coding to figure out which features they need and which will be supported by different browsers.

HTML5 simply builds upon the widespread success of HTML4. That means a coder doesn’t have to throw away the existing markup, but rather build upon and improve the old one.

4G

"4G" is the term used to refer to the International Mobile Telecommunications-Advanced (IMT-Advanced) technology family of mobile wireless services, which has been defined and ratified by the International Telecommunication Union (ITU). In an October 2010 meeting, The ITU's Radiocommunication Sector (ITU-R) Working Party 5D, which is responsible for defining the IMT-Advanced global 4G technologies, completed the assessment of six candidate technology submissions for the global 4G mobile wireless broadband technology. Of the proposals, two technologies, LTE-Advanced and WirelessMAN-Advanced, were each determined to have successfully met all of the criteria established by ITU-R for the first release of IMT-Advanced and were accorded the official designation of IMT-Advanced, qualifying them as 4G technologies. Final ratification of the full IMT-Advanced technology family took place at the ITU-R Study Group meeting on November 22 and 23, 2010, in Geneva, Switzerland.

As background for this IMT-Advanced project, ITU published a document, "Recommendation ITU-R M.1645: Framework and overall objectives of the future development of IMT-2000 and systems beyond IMT-2000."

These technologies will now move into the final stage of the IMT-Advanced process, which provides for the development in early 2012 of an ITU-R Recommendation specifying the in-depth technical standards for these radio technologies.
