I’ve an iframe with code that looks like this:
iframe#someID
html
head
body
first div
iframe points to file on the other domain. I want to replace styling of the div, effectively putting background-color:transparent; instead of color it already has.
Is this possible?
No, cross-site-manipulation is fortunately not possible.
To change the contents of an iframe on the same domain, however, have a look at this: http://api.jquery.com/contents/#example-1
