Specification of CSS 2.1

by Jasmine C
Since 2004, the W3C’s CSS Working Group has been working on creating an official specification for CSS and a decade later, they did.  CSS 2.1 was released June 2011 and it became the first official specification.  The author states that by CSS being the language style for the web, you can easily manage your pages and the content on your pages can be separated so that it can be viewed on different devices.  So much work has gone into the formation of CSS 2.1 because it is going to be the official specification for web styling.  CSS 2.1 has been tested repeatedly to make sure that it works with different browsers.  This allows for developers to ensure that the their features are presented the way they want on different browsers.  The working group has been in the process of developing CSS 3, which basically builds off of CSS 2.1, but instead of creating a whole new standard, CSS 3 is going to be released in different modules that will build CSS 2.1.

This article was really interesting.  Learning that it took a decade for the CSS 2.1 standard to form shows me that a lot of work and effort went into making sure that it is perfect (or as perfect as it can get). Also, the author said over 9,000 tests were run to ensure that browsers presented the CSS pages correctly.  I can see that a lot of work was put into the creation of version 2.1 and people can relate to this because whenever anyone wants to show off their work, they make sure that they test and re-test everything to make sure it’s up to par.  In class, I like learning how to manage the appearance of a website by specifying the presentation style because a website with good presentation has more views.

  1. CSS 2.1 took years in the making. I guess if you want reassurance in your tool, you have to be constantly testing it and improving where you can. Versatility and uses across various browsers is essential in having a successful tool.

  2. good article. I think it is a good thing that they made a set of standards for css because like the article said, it ensures that features work on every browser and it also makes it easier for other developers to come back and edit your code after the fact. I am assuming that the standards for CSS3 will just build on whats different between CSS2 and CSS3.

  3. Great article. I agree with the article. With so many different browsers, consistency of content is very important. With the standardization of css, Web pages will look more uniform across all browsers.
