David Grimm—online news editor for Science—talks with Sarah Crespi about the chance a naked mole rat could die at any one moment. Surprisingly, the probability a naked mole rat will die does not go up as it gets older. Researchers are looking at the biology of these fascinating animals for clues to their seeming lack of aging. Sarah also interviews freelancer Douglas Starr about his feature story on the Dunedin Multidisciplinary Health and Development Study—a comprehensive study of the lives of all the babies born in 1 year in a New Zealand hospital. Starr talks about the many insights that have come out of this work—including new understandings of criminality, drug addiction, and mental illness—and the research to be done in the future as the 1000-person cohort begins to enter its fifth decade.

What is the cascade?

The cascade is a mechanism for determining which styles should be applied to a given element, based on the rules that have cascaded down from various sources.

The cascade takes importance, origin, specificity, and source order of style rules into account. It assigns a weight to each rule. When multiple rules apply to a given element, the rule with the greatest weight takes precedence. The result is an unambiguous way to determine the value of a given element/property combination.

Browsers apply the following sorting logic:

• Find all declarations that apply to a given element/property combination, for the target media type.

• Sort declarations according to their importance (normal or important) and origin (author, user, or user agent). From highest to lowest precedence:

  1. user !important declarations
     
  2. author !important declarations
     
  3. author normal declarations
     
  4. user normal declarations
     
  5. user agent declarations

• If declarations have the same importance and source, sort them by selector specificity.

• Finally, if declarations have the same importance, source, and specificity, sort them by the order they are specified in the CSS. The last declaration wins.

What is specificity?

Specificity is a method of conflict resolution within the cascade.

Specificity is calculated in a very particular way, based on the values of 4 distinct categories. For explanatory purposes, the CSS2 spec represents these categories using the letters a, b, c, and d. Each has a value of 0 by default.

• a is equal to 1 if the declaration comes from a style attribute in the HTML (“inline styles”) rather than a CSS rule with a selector.
• b is equal to the number of ID attributes in a selector.
• c is equal to the number of other attributes and pseudo-classes in a selector.
• d is equal to the number of elements and pseudo-elements in a selector.

The specificity is given by concatenating all 4 resulting numbers. More specific selectors take precedence over less specific ones.

For example, the selector #id .class[href] element:hover contains:

• 1 ID (b is 1)
• 1 class, 1 attribute selector, and 1 pseudo-class (c is 3)
• 1 element (d is 1)

Therefore, it has a specificity of 0,1,3,1. Note that a selector containing a single ID (0,1,0,0) will have a higher specificity than one containing any number of other attributes or elements (e.g., 0,0,10,20). This is one of the reasons why many modern CSS architectural patterns avoid using IDs for styling purposes.

What is inheritance?

Inheritance is distinct from the cascade and involves the DOM tree.

Inheritance is the process by which elements inherit the the values of properties from their ancestors in the DOM tree. Some properties, e.g. color, are automatically inherited by the children of the element to which they are applied. Each property defines whether it will be automatically inherited.

The inherit value can be set for any property and will force a given element to inherit its parent element’s property value, even if the property is not normally inherited.

About !important

The above should make it apparent that !important is a separate concept to specificity. It has no effect on the specificity of a rule’s selector.

An !important declaration has a greater precedence than a normal declaration (see the previously mentioned cascade sorting logic), even declarations contained in an element’s style attribute.

Interview with Matthew Jeffrey Martin, MD, author of Courtesy Authorship in Academic Surgery Publications

Today marks ten years since the publication of HTML5 For Web Designers, the very first book from A Book Apart.

I’m so proud of that book, and so honoured that I was the first author published by the web’s finest purveyors of brief books. I mean, just look at the calibre of their output since my stumbling start!

Here’s what I wrote ten years ago.

Here’s what Jason wrote ten years ago.

Here’s what Mandy wrote ten years ago.

Here’s what Jeffrey wrote ten years ago.

They started something magnificent. Ten years on, with Katel at the helm, it’s going from strength to strength.

Happy birthday, little book! And happy birthday, A Book Apart! Here’s to another decade!
