CSS never had versions such as CSS v1.0, CSS v2.0, CSS v3.0 and so on. CSS is not a programing language. HTML and CSS are markup languages. In computer science, markup languages represent a class of languages specialized in enriching textual information. They use tags, syntactic units that delimit a sequence of characters or mark a precise position within a stream of characters (for example, a text file). The inclusion of tags allows you to transfer both the structure of the document and its content. This structure is understandable by a computer program, which allows automated processing of the content.
But I Know There Are CSS3 Experts
The phrase CSS3 bears no meaning. CSS has levels (of progress or development) such as level 1, level 2.1, level 3 and so on. But the numbers indicate the addition of new features and/or vocabulary. CSS Level 3 is built on CSS Level 2 and it became modular. The phrase CSS3 is used only to indicate that it is not the previous monolithic version.
Basic CSS remained the same even before the phrase CSS was coined. Before CSS, the attributes of HTML documents were contained within the HTML markup. Sometimes inline style was used before 1994.
acme.com is one of the old sites which looks the same even in 2023.
www.toad.com is kind of the oldest personal website.
We do use that method still today. Later it was planned to move as a file named cascading HTML style sheet. The phrase
cascading is for indicating something like competition.
In September 2012, representatives of the W3C’s CSS Working Group clarified that there should be no version number 4: “There will never be a CSS4”.
More About CSS
Håkon Wium Lie is a Norwegian web pioneer, who was the Chief Technology Officer of Opera Software and is best known for developing Cascading Style Sheets (CSS) while working with two others at CERN. You can look at his website
His philosophy was to keep it simple and easy to self-learn.
CSS is not like a real programming language, It doesn’t compile. It has no error checking unless you use some IDE tools. Dynamic CSS, or DCSS, is an umbrella term for a set of technologies used to create dynamic stylesheets, using a combination of any server-side programming language (such as PHP/ASP/Perl/JSP) and cascading style sheets (CSS). The first idea for DCSS was proposed in July 2002.
One of the major goals of CSS is to enable formatting outside of documents. For example, it is possible to describe only the structure of a document in HTML and to describe the entire presentation in a separate CSS style sheet. Styles are applied at the last moment, in the web browser of visitors who view the document. This separation provides several benefits, making it easier to change layout, and reducing the complexity of a document’s architecture. Thus, the advantages of style sheets are multiple:
- The document structure and presentation can be managed in separate files.
- The design of a document is done at first without worrying about the presentation, which makes it possible to be more efficient;
- In the case of a website, the presentation is standardized: the documents (HTML pages) refer to the same style sheets. This feature also allows a quick reshaping of the visual aspect;
- The same document can choose between several style sheets, for example, one for printing and one for reading on the screen. Some web browsers allow the visitor to choose one style from several;
- HTML is significantly reduced in size and complexity since it no longer contains tags or presentation attributes.
- CSS made it easy to work with dynamic programming languages, such as PHP.
