Quoting Jon Trelfa:
I've got a document I've been working on that uses a background image
that moves for rollovers (tabs). In FF, everything seems to operate
smoothly. In IE, however, a message shows up in the status bar that
it's 'downloading' the image everytime I roll the mouse over a tab?
Sometimes it's a really fast message, but it really shows up poorly on
a dialup connection.
Is this normal behavior?
It appears as if under Internet Explorer, CSS is handled in such a way that
backgrounds are re-rendered when re-positioned.
Do I need to preload the image or something?
I think you might have to separate
http://pps.esynergymedia.com/images/tab-bg.gif into 3 separate bits and no
pre-loading will be necessary.
I don't think pre-loading would do the trick. Images should be preloaded when
they do not appear until something triggers it. In this particular case, you
only have a single images that appears from the very beginning.
It's very odd (and annoying) because the browser shouldn't be
downloaded everytime the person rolls over a tab.
[typo] image, not browser
You can (perhaps should) render the entire tab menu without any
graphics and use
pure-CSS solutions. With plain, uniform colour in the background, there is no
justification for images either. See examples here:
