Impossible to create a transparent background page to insert into an iframe

Question

Hi,
I am trying to insert a page created in Muse inside another page by using an iframe in an HTML inclussion. I want it to be transparent so the background of the container page shows thru. The problem is Muse always gives a background color to any page it does, so the iframed page background is no transparent.
My iframe code is:
<iframe src="biografia2.html" width="630" height="566" seamless frameborder="0"></iframe>
And the biografia2 page loads its corresponding CSS file that begins with:
html
    background: #D9D9D9;
If after exporting the site I remove these lines in the CSS file, the iframe appears transparent.
This lines are generated because in the Muse editor, when nothing is selected, so you have the page properties in the toolbar, the last control is the colour of the background of the browser, but you can't set this colour to null, so the page always has a colour. I think this is a bug in Muse that should be corrected.
Until then, the only solutions I can see are removing the mentioned lines manually after exporting the HTML or creating the iframed page without using Muse.

Answer 1

Hello,
In order to achieve this, you need to open your page biografia2.html in Muse and then Right Click and go to the Page properties.
There in HTML for head section you need to insert the code :
<style>
body{
background:transparent !important;
</style>
It will override the styling and the Background will be transparent for that page.
Hope this helps.
