There are many scripts that present a method for setting the iframe's height to match its contents. But I looked in vain for a script that integrates the iframe in a completely seamless way into the containing document. So I tried to write a script for emulating seamless iframes myself.
My seamless iframes are competely indistinguishable from the surrounding text/content and inherit their css from the main document. All the code is put in the main document. No special code required in the
I knew that it is possible to programmatically force the browser to open a new window instead of a new tab, or the other way round. But I didn't know until now how to open a new tab together with text or code 'of my choice'.
The text or code we may want to 'add' to a new tab must have the format of a string. The more complex the text or code we want to add, the bigger the danger of making mistakes in writing the string.
I learned a few things after I posted this on my blog about putting a close button on top of centered fluid images.
I used jquery and translate in CSS transforms there to do the job. But I found that it can also be done with the help of a combination of window.innerWidth/Height and element.clientWidth/Height. As window.innerWidth/Height and element.clientWidth/Height are also supported by older browser, a technique using these methods must be preferred. Demos and explanations here.

The translate() method used inside the HTML-code below moves both a (super) div-containing-a-close-buttom (id: 'the_div') and an image (id: 'the_img') to the center of the window. The jquery-onload in the image ensures that the width of the div equals the width of the image. This is a requirement if we want to get the button (in the div) at the right position in front of

If we want to use the browser's scrollbar to scroll the content of an iframe, we must do the following:
calculate iframe's offsetHeight + pixel distance of top of iframe with respect to top of main window + pixel distance of bottom of iframe with respect to bottom of main window ;give the main window a pixel height that is identical to the result of that calculation;make sure that the value for the number of pixels that the content of the iframe is scrolled upward (in the case of
