Easy Font Resize

This plugin puts a smile on my face... no issues thus far !

Actually I would love the plugin to store the font size state in a cookie (or database), so users do not have to keep resizing with every page load.

Very Good.

Include content the way YOU like in an iframe that can hide and modify elements, does auto height, forward parameters and does many, many more…
<h4>Main features of advanced iframe</h4>
By entering the shortcode ‘[advanced_iframe]’ you can include any webpage to any page or article.
Advanced iFrame now has out of the box support for embedded 3D models using the p3d 3D viewer. Go to https://p3d.in/b/24 and download a pre-configured plugin where the model does scale already nicely on all devices. Get started for free! If you need more storage or access to the Premium features of p3d.in, you can get a 50% discount on your first payment with the coupon AIFRAME on checkout.
The following cool features compared to a normal iframe are implemented:
<ul>
<li>Hide areas of the layout to give the iframe more space (see screenshot)</li>
<li>Show only specific areas of the iframe when the iframe is on a same domain (The Pro version supports this on different domains) or include parts directly by jQuery</li>
<li>Modify css styles in the parent and the iframe to e.g. change the width of the content area (see screen-shot)</li>
<li>Forward parameters to the iframe</li>
<li>Resize the iframe to the content height or width on loading, AJAX or click</li>
<li>Responsive videos (moved from the pro to the the free version in v2022)</li>
<li>Scroll the parent to the top when the iframe is loaded</li>
<li>Hide the content until it is fully loaded</li>
<li>Add a css and js file to the parent page</li>
<li>Security code: You can only insert the shortcode with a valid security code from the administration.</li>
<li>Many additional cool features are available the pro version – see https://www.advanced-iframe.com/advanced-iframe/advanced-iframe-comparison-chart</li>

</ul>
<h4>Quick start guide</h4>
The quickstart guide is also available as video: https://www.advanced-iframe.com/advanced-iframe/advanced-iframe-video-tutorials
To include a webpage to your page please check the following things first:
<ul>
<li>Check if your page page is allowed to be included https://www.advanced-iframe.com/advanced-iframe/free-iframe-checker!</li>
<li>Check if the iframe page and the parent page are one the same domain. www.example.com and text.example.com are different domains!</li>
<li>Can you modify the page that should be included?</li>
</ul>
Most likely you have one of the following setups:
<ol>
<li>iframe cannot be included: You cannot include the content because the owner does not allow this.</li>
<li>iframe can be included and you are on a different domain: See the feature comparison chart: https://www.advanced-iframe.com/advanced-iframe/advanced-iframe-comparison-chart and the feature overview https://www.advanced-iframe.com/advanced-iframe/advanced-iframe-features-availability-overview. To resize the content to the height/width or modify css you need to modify the remote iframe page by adding one line of Javascript to enable the provided workaround.</li>
<li>iframe can be included and you are on the same domain: All features of the plugin can be used.</li>
</ol>
If you mix http and https read https://www.advanced-iframe.com/iframe-do-not-mix-http-and-https. Parent https and iframe http does not work on all mayor browsers!
<h4>Advanced iframe attributes</h4>
Below you find all possible shortcode attributes. If you only use one iframe please use the settings in the administration because there each parameter is explained in detail and also the defaults are set there.
Setting an attribute does overwrite the setting in the administration.

Advanced iFrame


Tried this wanting a vertically responsive iframe, but the free version doesn't do that.  The plugin descriptions lists a dozen "cool features" but in fact they're all only available in the commercial version.  Specifically the one that reads "Resize the iframe to the content height or width on loading, AJAX or click".   Tried a few things to get it working, gave up.


Free version doesn't do any of the things listed as "cool features"

Include content the way YOU like in an iframe that can hide and modify elements, does auto-height, forward parameters and does many, many more...
