Make iframe transparant

Hi guys,

How do I make an iframe on my forum transparant?
This is the iframe I mean:


This is the code I used:

Code:

<iframe frameborder="1" height="29" name="frame1" scrolling="no" src="that link" width="375" ALLOWTRANSPARENCY="true"></iframe>

As you see, 'Allowtransparency="true"' doesn't work...

Can anybody help me?

Thanks in advance!

Hi!

Add in CSS Stylesheet:

Code:

iframe{
background-color: transparent !important;
border: 0px !important;
}
