<?php _e('You can only show a part of the iframe. This solution DOES WORK across domains without any hacks! This is a solution that works only with css by placing a window over the iframe which does a clipping. All areas of the iframe that are not inside the window cannot be seen. Please specify the upper left corner coordinates x and y and the height and width that should be shown. Specify a fixed height and width in the iframe options at the top for optimal results! I recommend to make the iframe itself that big that no scrollbars do exist anymore. Otherwise scrolling e.g. with the mouse wheel on some browsers is possible. Simply select the area you want to show with the graphical area selector! You can even zoom the selected area that it fits properly e.g. on a mobile phone. Please go to the <a target="_blank" href="//www.tinywebgallery.com/blog/advanced-iframe/advanced-iframe-pro-demo/show-only-a-part-of-the-iframe">pro demo</a> for some working examples.

This is pretty cool and can be configured by pressing the "Add breakpoint" link. There you can define the x, y, width, height and iframe width for a certain browser width (breakpoint). See the descriptions before for a description of this values. You always define the upper width of a breakpoint. So if you want to optimize your iframe for mobile, table, desktop you can define 2 view ports. You can also only enter one value you want to change. Now the interesting part is coming. You cannot simply set the width of the iframe itself to 100% to have it responsive because it will than have the same size as the viewport. The plugin will set the width to the breakpoint width when you reach this value or the iframe width if you define one. You can use the area selector by entering the breakpoint or iframe with for this breakpoint as width and select the new area. Please check the example for a full explanation. If you want to define this in a shortcode you have to define x,y,width,height,iframe witdh and a breakpoint separated by |. e.g. show_part_of_iframe_media_query="80|100|800|600|1024,100|40|600|400|800".

There the structure stays like before. Only elements are hidden! Often a background is defined for the header which you can remove below e.g. by setting background-image: none; in the body.

The disadvantage is that adding the style element is still done after the iframe is fully loaded and that writing valid css is a little bit more complicated. Use "Write css directly" for the external workaround. Enter the styles without &lt;style&gt;. E.g. iframe_content_css="body { margin: 0 !important; }". The value is sanitized at the output!
