Corner Ad is a minimally invasive advertising display that uses any of your webpage’s top corners – a position typically under-utilized by developers – and attracts users’ attention by a cool visual effect imitating a page flip. Corner Ad initially displays a partial ad, which attracts attention; when user hover the mouse over it, the ad opens to its full size while imitating a page-flip effect; once the mouse is moved away, the ad returns to its initial size.
Corner Ad can also be used for announcements, newsflashes, and basically for anything else that you consider important and want your website visitors to see. It is common nowadays that visitors quickly scan the contents of a page and often fail to notice messages that you would like them to see; Corner Ad attempts to resolve this issue.

Inserting the Ad
To inset the ad into a post or page open the post/page for editing and use the “Corner Ad” icon that is located above the editor.
A floating panel will appear allowing the selection of the corner ad to be inserted into the post/page. Once selected a shortcode with the ad’s ID will be inserted into the content., for example: <code>[corner-ad id="3"]</code> (the 3 is the ID of the ad in this sample).
To insert an ad directly into the website theme to display it across all the pages or into specific sections, edit the template and insert the following code fragment:
<pre><code><?php echo do_shortcode('[corner-ad id="3"]'); ?>
</code></pre>
To identify the ID that belongs to each ad, go to the page in the settings area where the ads are created. On that list each ad has its shortcode with its ID.
