With the Internet dominating each and every facet of our lives, web applications and designer web pages have become more indispensable and significant than ever before. Given this scenario, Cascading Style Sheets (CSS) are working in unison with HTML and other web development elements to create useful style and structure.
Through this article, we aim to throw light on the advanced features of CSS 3, the difference between CSS and CSS3 and the definitions of CSS and CSS3. We begin with a CSS vs CSS3 comparative chart that follows below.
CSS vs CSS3
|Basis of Difference||CSS||CSS 3|
|Compatibility||Designed to offer several formatting features, CSS is not compatible with CSS3.||CSS3 provides backward compatibility with CSS and supports all codes written in CSS version 1.|
|Rounded gradients and corners||In CSS, designers had to develop rounded borders separately from the other web page elements and then position them on the server to complete the look.||CSS3 allows for the setting of rounded gradients and corners with the help of codes.|
|Support for media queries||Media queries are not supported by CSS||CSS3 supports queries for responsive websites|
|Splitting into modules||CSS codes cannot be split up into varied modules||CSS3 codes are capable of being split up into different modules|
|Support by new browsers||CSS codes are not supported by all types of new browsers||CSS3 gains support from all new browsers|
|Colours||CSS offers standard and old colours only||Support is provided for RGBA, HSL HSLA and gradient colours|
CSS allows users to:
CSS3 lists must have the ‘display’ properties defined in them. List items have counters that are directly affected via counter increments as well as counter reset properties.
CSS is equipped to separate presentation and content; this includes the separation of layouts, fonts and colours. This feature of CSS allows for better content accessibility, enhanced flexibility and control, as well as specification of the characteristics of presentation.
CSS enables varied and multiple web pages to share the formatting via specifications of relevant CSS in separate .css files. Overall, CSS reduces complexity/repetitions in the structural and elements of web pages.
Cascading Style Sheets Level 3 (CSS3) refers to an iteration of different CSS standards that are used for structuring, styling and formatting web pages. It incorporates different CSS2 standards and includes important changes and improvements.
One important feature of CSS3 is the divisibility of CSS standards into separate modules that are simpler to decipher and learn. While some features are still awaiting the nod of the World Wide Web Consortium (W3C), a large number of CSS3 properties have already been implemented and are supported by the latest versions of new browsers.
New Features of CCS3
The advanced features of CSS 3 are:
- Combinator: CSS3 offers the new General Sibling Combinator that can match up with the sibling elements of specific elements via the tilde (~) Combinator.
- CSS Selectors: CSS Selectors: In comparison to the 'simple selectors' offered by CSS2, the components in CSS3 can be referred to as 'a sequence of easy to use and simple selectors'.
- Pseudo-Elements: In the latest version of CSS3, plenty of pseudo-elements have been incorporated to give off in-depth but easy styling as well as new conventions of double colons '::'.
- Background Style Properties: CSS3 users can opt for multiple background images that are capable of being layered in a specific box with different elements such as background images, positioning and repeat features. Background-clips, size, style and origin properties have also been added.
- Border Style: The styling of borders in CSS3 includes images and corners with rounded designs. Border-radius, image-slice, image-source and values for width stretch and outset have also been newly added in CSS3.
The above differences between CSS3 and CSS depict the gradual transformation of features and functionality of the first version of CSS to the latest one. In case you have any further queries, do write to us in the comments section below, we will get back to you at the earliest.
