CSS3 Support

Amazon Silk supports basic CSS3 features like backgrounds, opacity, rounded corners, and text effects, as well as other features. Though not intended to be comprehensive, this page describes supported features and notes Amazon Silk-specific implementation details, where applicable.

Media Queries

Media queries provide a way to apply style rules based on particular media features like width, height, and resolution. Using media queries, you can deliver layouts that, in effect, respond to the form factor of the user agent.

Media queries are a key component of Responsive Web Design. You can use media queries to create a fluid grid that responds to changes in viewport size. (For more on the viewport, see viewport Meta Element). You can also tailor the user experience to device orientation, so that your layout changes as the user goes from portrait to landscape mode.

To learn more about media queries, see the following resources:

Transform Property (2D)

The CSS3 transform property can be used to rotate, scale, skew, and otherwise alter an element. You can use the transform property to make a web page more interactive.

For more information, see CSS3 transform Property.

Transitions

Using a CSS3 transition, you can add an effect to a property change, without employing JavaScript. The result is an element that changes from one style to another, like an animation.

For more information, see the W3C specification CSS Transitions.

viewport Meta Element

The viewport represents the display area available to the browser. The viewport can be bigger or smaller than the physical screen of the device, and it doesn't include browser chrome (the browser borders and controls). For some calculations, it may be useful to differentiate between a visual viewport (the dimensions of the area visible on the screen) and a layout viewport (the dimensions of the entire display area). For more on the visual and layout viewports, see Peter-Paul Koch's A tale of two viewports — part two.
