![]() ![]() Next is the 13th, then the 15th, and so on. Since n starts at 0, the first tr element to be affected is the 11th. The following rule will set the background colour of all div elements whose id begins with “nav”: div This whole group of selectors is new, and the selectors in it let developers match substrings in the value of an attribute.Īssume that you have an HTML document that contains the following markup structure: īy using the substring matching attribute selectors you can target combinations of these structural parts of the document. Each selector will be described in more detail in this article, and there are examples of how each selector can be used. ![]() If all that doesn’t make much sense right now, don’t worry.

If you need a refresher, a good place to start is CSS 2.1 selectors, Part 1.įirst, a quick overview of the selectors that are new in CSS 3: Overview of CSS 3 selector syntax Selector type I am not going to explain the basics of how CSS selectors in general work here. If you are reading this article months, or even years after that date it may be worth checking if a more recent version is available. The new selectors described in the document will be used by CSS level 3, but may also be used by other languages. In this article, the specification I am referring to is the Selectors W3C Working Draft 15 December 2005. However, there are cases where they can be used to add nice forward enhancing features, so I think taking a look at how the new selectors in CSS 3 work can be useful. Many of the CSS 3 selectors have already been implemented in modern browsers, but in general support is far too patchy for developers to rely on these new selectors. If we look a little further ahead, there are even more powerful selectors waiting to be implemented and used in CSS 3. The good news is that Internet Explorer will catch up, at least to some extent, with the release of version 7. We just need to wait for Internet Explorer to catch up before we can start using the full power of CSS 2.1 selectors. A quick summary is that most of the selectors described in those articles can be used now in modern browsers like Mozilla/Firefox, Safari, and Opera. In September and October of 2005 I published a series of articles that explained the selectors that are available in CSS 2.1. ![]()
