I have a html page with an IFrame linking towards a text file, my html page's body is set to black, and the default color of the IFrame txt is black, so I cannot see my text :/ I would like to know how to change the text color, thanks. zeokila

<iframe src=".txt" width="470" frameborder="0" marginheight="0" marginwidth="0" style="overflow-x:hidden"></iframe>

• Not a dup. This is a text file with .txt extension. – Teemu Commented Apr 22, 2012 at 19:20
• try importing the file as an object – hjpotter92 Commented Apr 22, 2012 at 19:21
• This might be a stupid question, but how can you set a black background for the IFRAME, if there is txt file loaded? By default it is white. – Teemu Commented Apr 22, 2012 at 19:34
• 2 Good question. Upvoting. And who was the joker who wants to close this as "not a real question"? – Mr Lister Commented Apr 22, 2012 at 20:26

Sorted by: Reset to default 4

This makes the trick at least in FF, IE and Opera.

document.getElementById('your_iframe_id').contentWindow.document.body.style.color='white';

In Chrome you can only change IFRAMEs background color:

document.getElementById('your_iframe_id').style.background='white';

And for change background color in IE:

document.getElementById('your_iframe_id').contentWindow.document.body.style.backgroundColor='yellow';

Then there is a big but... those expressions including contentWindow, work only, if the iframe and the host page are in the same domain.

(It is IE only having that white background by default)
