CSS GUIDE -MOZ-OPACITY
This document is a work in progress and is subject to change.
Summary
- Firefox allows you to use coding to manipulate the opacity of an image.
- "Opacity" refers to transparency; the lesser the opacity of an image, the more transparent it is.
| Applicability: | The background-repeat property can be used for all CSS elements. |
| Media Group: | Visual |
| Inherited: | No |
Syntax
If a background image is specified, this property specifies whether the image is repeated (tiled), and how. All tiling covers the content and padding areas of a box. A value of 'repeat' means that the image is repeated both horizontally and vertically. The 'repeat-x' ('repeat-y') value makes the image repeat horizontally (vertically), to create a single band of images from one side to the other. With a value of 'no-repeat', the image is not repeated.:
BODY {
background: white url("pendant.gif");
background-repeat: repeat-y;
background-position: center;
}
Legal Values
The following units are valid for defining background-repeat:
- repeat
- The image is repeated both horizontally and vertically.
- repeat-x
- The image is repeated horizontally only.
- repeat-y
- The image is repeated vertically only.
- no-repeat
- The image is not repeated: only one copy of the image is drawn.
