Retaining background image in iframe

[Fokke Nauta]

Hi all,

I have a table with a few cells. The table has a background image. One of
the cells contains an iframe. In this cell the table background image is no
longer visable. I would like to see the background image shine through this
cell as well, so making this iframe cell sort of transparent for the table's
background image.
Can this be done? If so, how can I manage this?

Thanks in advance.

With kind regards,
Fokke Nauta

Hi all,

Thanks for your quick responses.
I did not know that it was possible but it was indeed.

I gave the body-tag in the iframe document this argument:
STYLE="background-color: transparent;"
In the iframe code in the parent document I put this: ALLOWTRANSPARENCY
I even found that you can also make the scrollbar track transparant with
putting this in the iframe code: style="FILTER: chroma(color=#fffffe)"
In order to have the latter work I had to set the scrollbar track colour to
=#fffffe in the style sheet.
It all works! Not in all browsers but at least in MSIE and Firefox. Firefox
however does not show the scrollbar track transparency.

With best regards
Fokke

Yes it can be done, and it is what is supposed to happen.

I just tested it and it works in Firefox and Opera, but not Konqueror.

See CSS 2.1 Appendix E.2:

The canvas is transparent if contained within another, and given a
UA-defined color if it is not.

Konqueror gives the iframe canvas the UA-defined colour (i.e. white),
which is wrong. It's meant to be transparent.

So, in Konquerer, you are not seeing a bg in the left cell in:

?

In Mac Safari it shows, as in all my browsers except MacIE. Don't know
about Windows browsers yet on this one.

I've never heard of ALLOWTRANSPARENCY or FILTER, presumably they're IE
extensions.

Indeed, they are IE extensions.

But it should be transparent in Firefox anyway as discussed (and is as
one can see from dorayme's example).

Yes, that works allright.
Thanks!
