Hello,
>From my experience with sprites, you wouldn't be using an image tag to
render the sprite. Rather, you would be giving an id or class
attribute on a div or some other type of HTML container tag that
positions the background image (sprite) and possibly sets a width and
height on the container to prevent overflow.
>From an organizational standpoint, knowing which images are in a
sprite would be nice, but from my perspective, this might get to be a
maintenance nightmare. Sometimes you need extra space between sprites
or you might want to do selective optimization on the image, etc.
Plus, you might end up with inline-css to position the background
image within each element, which would make it impossible to override
from a css file.
All that being said, probably not worth the effort from my experience
as a presentation layer architect on big and small projects.
Kindest regards,
Brandon
