ISSUE-9: Splitting 'background-position' into -x and -y allows to quickly change one without the other
background-position-x/y
Splitting 'background-position' into -x and -y allows to quickly change one without the other
- State:
- CLOSED
- Product:
- CSS3 Backgrounds and Borders
- Raised by:
- Anne van Kesteren
- Opened on:
- 2008-04-04
- Description:
- The use case is described here:
http://lists.w3.org/Archives/Public/www-style/2004Aug/0185
Basically, it enhances a well-known technique to avoid a download and a slight delay by putting two background images into one and moving it up and down on hover rather than replacing it: By splitting 'background-position', one avoids having to repeat the x coordinate in the rule for ':hover'.
Elika and Bert considered the use case too weak to introduce new properties for. See http://lists.w3.org/Archives/Member/w3c-css-wg/2008JanMar/0153.html - Related Actions Items:
