How to Remove an IFrame from head section !!

Hello Guys,
I wanna remove an iframe of head section from website.
This is the code that removes all iframes(obviously):

iframe{display:none!important;}

Code (markup):

But when i try to remove iframe from head section using this code:

#fw-head {iframe display:none!important;}

Code (markup):

(Doesn't Work)

So need a code for removing an iframe in head section that works.

 

doesnt need a code anymore.

 

i remove that element using another css code.

 

I dont understand your question, if you want to remove the Iframe just remove <iframe>...</iframe>

 

or you could comment it out using #iframe{display:none!important;} (php) or <--!iframe{display:none!important;}--> (html)
