Modal windows are interesting way to include extran information on a page. <a href="http://www.onextrapixel.com/2014/06/25/create-modal-windows-that-can-be-morphed-from-anything-with-jquery-adaptive-modal-js/" rel="nofollow ugc">adaptive-modal.js</a> makes it beautiful. You can use this little plugin which uses the same jQuery plugin to creae modal windows easily in any page or post or even on a widget uisng shortcode.
I have also added another functionality into this plugin, which will let you to embed your modal content into your post a page directly.
<h3>Usage</h3>
Upon activation, the plugin will create a custom post type called ‘Modals’. Where you can add your content, which later you can use it on a modal or embed directly into your page or post.
<ol>
<li>[modal]</li>
<li>[block] </li>
</ol>
<h3>modal</h3>
the ‘modal’ shortcode is to create modal windows.
For now the [modal] shortcode comes with four attributes.
id 
Your modal id. eg: [modal id=2]Click here[/modal]
data 
If your modal only going to have just text, you can directly add the content in the shortcode. eg: [modal data=”This is my modal content”]Click here[/modal]. This shortcode is much useful when you want to add a modal window to a word in a paragrap without braking the paragrap.
<pre><code>note: you cannot use both id and data in the same shortcode
</code></pre>
background 
This is to style the link and the modal window background. Have to specify a valid color. eg: [modal id=2 background=”#DDDDDD”]Click here[/modal]
color 
This attribute is to change the color of the link. eg: [modal id=2 background=”#DDDDDD” color=”#000000″]Click here[/modal]
<h3>block</h3>
The ‘block’ shortcode is to embed your modal content into any page or post. It only has one attribute.
id 
id of the modal post type post.
<pre><code>note: both block and modal shortcodes uses the same Modals custom post type.
</code></pre>

FooBox adds a lightbox to your WordPress site, so images are loaded in a modal or popup instead of redirecting your visitors away from your site.
Some people often refer to a lightbox as an “Image Zoom” effect. It’s really just a modal overlay or popup that showcases your images.
FooBox was the first lightbox to take responsive layout seriously. Not only does it scale images to look better on phones, but it rearranges it’s button controls to look great in both portrait or landscape orientation.
Add a modal popup to your website images with no setup. FooBox will automatically add modals to WordPress galleries, WordPress images with captions, and attachment images.
NEW: Auto Link Existing Images
Have older posts with images that do not open in FooBox? That is probably because those images were inserted without linking to the full-size media file. 
Enable Auto Link Existing Images and FooBox will automatically wrap unlinked WordPress attachment images on the frontend, so visitors can open them in the lightbox without you editing old content.
Works with most image gallery plugins, but works best with our <a href="https://fooplugins.com/foogallery-wordpress-gallery-plugin/" rel="nofollow ugc">FooGallery Gallery WordPress Plugin</a>.

Complete FooBox Asset Control
By default, FooBox lightbox includes javascript and stylesheet assets into all your pages. We do this, because we do not know if the page content contains media or not. 
If you want more control over when FooBox assets are included, you can now exclude the assets by default, by enabling a setting. Then on each page, you can choose to include them when required. 
Alternatively, you can leave the setting disabled, and then choose to exclude the FooBox assets from particular pages. A new metabox is now available when editing your pages or posts. 
This new feature was only available in the PRO version beforehand, but we feel control over your website performance is something you should not have to pay for. Enjoy!

Lightbox & Modal Popup WordPress Plugin – FooBox


it´s easy to get going right after the install! not too complex as I am needing it for "single" images to lightbox! really excellent!!!!!!


wonderful!

stops working after 7 days


FooBox works great ouf of the box (pun intended) and is well-suited for sites that need a quick image lightbox plugin that plays well with others.



The default lightbox theme provided is professionally made and well-suited for showcasing screenshots, portfolio items, photography, and more.



If you need more layout choices and compatibility with even the peskiest lightbox plugins, please check out Pro, as it's the only license I don't hesitate to renew.


FooBox is fantastic
