CSS is a general term for Style Sheets... as in "Learn CSS"

 

CSS aka CSS 1 is the original language.

 

CSS 2 was an improvement.

 

CSS 3 is just a further improvement/reworking of the language.

 

There are changes between the versions but the language is the same.

css means cascading style sheet and The latest version of CSS is the CSS3 version which basically differs from CSS2 in the incorporation of Modules and other changes. Modules enable the designing to be done in a lesser time with more ease while updating individual features and specifications. The CSS3 version supports many more browsers than CSS2, but be sure to test it on all operating systems and browsers.

Other major changes/additions include:

 

* New Combinator

* New CSS Selectors

* New Pseudo-elements

* New Style properties

hello...

I mention some small and important points which can separate CSS and CSS3 .CSS is used to control the style and layout of Web pages.CSS3 is the latest standard for CSS. Modules are a new concept in CSS3 . Multiple backgrounds is another feature in added in CSS3. With CSS, having multiple backgrounds would have required using a number of HTML tags and div tags to render them on a Web page. With CSS3, the new and improved "background-image" property allows the lying of image layouts on top of each other.

The biggest difference between CSS2 and CSS3 is that CSS3 has been split up into different sections, called modules. Each of these modules is making it's way through the W3C in various stages of the recommendation process. CSS2 was submitted as a single document with all the Cascading Style Sheets information within it. Because each of the modules is being worked on individually, we have a much wider range of browser support for CSS3 modules.

Talking about the difference between CSS and CSS3, Can anybody tell me please, how can I show that I am using CSS or CSS3. I mean in HTML <!DOCTYPE> is used to define the version. So, anything special to do before using CSS3?

hello

I am trying to differentiate CSS and CSS3

The biggest difference between CSS and CSS3 is that CSS3 has been split up into different sections, called modules. CSS3 well interacts with HTML5. In CSS3 some new features have been added.With CSS3 you can do animations, shadows, flip,rotate elements, and much more features that you can no find in CSS.

The latest version of CSS is the CSS3 version which basically differs from CSS2 in the incorporation of Modules and other changes. Modules enable the designing to be done in a lesser time with more ease while updating individual features and specifications. The CSS3 version supports many more browsers than CSS2, but be sure to test it on all operating systems and browsers.

Other major changes/additions include:

 

* New Combinator

* New CSS Selectors

* New Pseudo-elements

* New Style properties

 

Now let us discuss these in detail.

 

Combinator

New addition of General Sibling Combinator is done to match sibling elements of a given element through tilde (~) Combinator.

 

CSS Selectors

While CSS2 had ‘simple selectors’, the new version calls them the components as ‘a sequence of simple selectors’.

 

Pseudo-Elements

Many Pseudo Elements have been added that allow in-depth yet easy styling and a new convention of double colons ‘::’ has been introduced.

 

Style Properties

 

New Background Style Properties

Multiple Background images can be layered in the box using different elements like background image, position and repeat.

 

Border Style

Styling of borders has been extended to images and rounded designs which includes creating image of the borders and then automatically apply image to the borders through CSS.

 

Additions in Properties

 

* Border-radius, image-source, image-slice, and the values for width outset and stretch have been added in CSS3.

* Properties for managing boxes like shadowing, wrapping and breaking have been added.

* CSS3 has done away with complex structures for div tag and makes it easy for hassle free designing of multiple table-less columns. This can be simply done by putting in the number of columns in the browser that need to be added in the body element along with their width, color and height to make the text flow through the columns with ease.

 

New Background Style Properties

 

* With the addition of the new ‘local’ value, if the element has a scroll bar then the background scrolls with its content.

* Background-clip, origin, size and style properties have been added.

* Background shorthand property has been added in the size and origin properties.

* The changes to previous Background Style Properties include:

 

Repeat property now has two values name space and round that space the tiled image in the box uniformly and rescales background images to tile it multiple time in the box.
