I know that ALT text is supposed to augment the image … be of use to the visually impaired, etc, but I am thinking of Google Charts and want to use it as a warning …
If the image can’t be seen, for some reason, my ALT text is “Unable to create chart. Check internet connection or report program error” (cos Google Charts is quite delicate & it’s easy to feed it a chart description which it doesn’t understand, in which case there is no image)
However, even if the image can me seen, some/many browsers show the ALT text when the cursor hovers over the image, which is confusing to the user.
So, since I’m not much of a CSS guru, how do I prevent the ALT text showing on cursor hover over a Google chart image?
hovering over the image usually displays the value of the
titleattribute. Maybe try explicity giving it an empty value.
