Hi,
I
have been studying the MinimalExtropy skin that comes with DNN V5 as I am considering
using it as a basis for my own designs. I have specifically been looking at the
use of PNG and GIF images and I am trying to understand why some PNGs are
replaced with a GIF version, when the browser in use is IE6, and some are not. I understand
the PNG problem with IE6 and I understand that some PNGs are not being replaced
because they have no transparency and therefore it is not necessary; specifically:
<!--[if !supportLists]-->1.
<!--[endif]-->Body_bg.png
<!--[if !supportLists]-->2.
<!--[endif]-->Bread_bg.png
<!--[if !supportLists]-->3.
<!--[endif]-->Logo_top_bg.png
<!--[if !supportLists]-->4.
<!--[endif]-->Menu_bg.png
Here
is what I don’t understand: Why have they chosen to use GIF files for all
browsers with the menu active and menu hover images; specifically:
<!--[if !supportLists]-->1. <!--[endif]-->Menu_active.gif
<!--[if !supportLists]-->2. <!--[endif]-->Menu_hover.gif
<!--[if !supportLists]-->3. <!--[endif]-->Submenu_active.gif
<!--[if !supportLists]-->4. <!--[endif]-->Submenu_hover.gif
They
have also used a GIF for search.gif.
They
seem to be very intentional with their design so I am sure there is a logical
reason for their choices but I don’t understand. Anyone have any ideas? I would
like to understand why I am doing something before I proceed. Thanks for your
help.
Regards,
Fred
