CSS3 PIE is a .htc file that faithfully recreates css3 styling in early versions of internet explorer. Simply adding "behavior: url(path/to/PIE.htc);" at the end of the selectors scope that contains the CSS3 rule causes it to render correctly in otherwise unsupported versions of IE.
"CSS3 allows us to create shadows with only a couple of lines of code, the style in charge is "box-shadow".
To create a Photoshop-like Drop Shadow you can use the following syntax:
box-shadow: ;
To create a Photoshop-like Inner Shadow you can use the following syntax:
box-shadow: inset ;"
Spin.js uses the CSS3 to render the UI, falling back to VML Internet Explorer. If supported by the browser, @keyframe rules are used to animate the spinner. The spin() method creates the necessary HTML elements and starts the animation. If a target element is passed as argument, the spinner is added as first child and horizontally and vertically centered.
This page was created to calculate the CSS specificity of a stylesheet (not including the inline or style rules; the "a" part of the equation). Before this little project, I didn't have a clear understanding of the specificity rules. Now, after creating this page, I don't think I'll need this application.
Specificity is a mechanism within the CSS cascade that aids conflict resolution. The concept of specificity states that when two or more declarations that apply to the same element, and set the same property, have the same importance and origin, the declaration with the most specific selector will take precedence.
Specificity Calculator isn't a CSS validator. If you enter invalid selectors it will return incorrect results. For example, the negation pseudo-class may only take a simple selector as an argument. Using a psuedo-element or combinator as an argument for :not() is invalid CSS3 so Specificity Calculator will return incorrect results.
