This plugin is based on <a href="https://wordpress.org/plugins/tiny-url/" rel="ugc">Prasanna SP Tiny URL</a> plugin and uses some of its code.
This plugin shows a short URL for each of your blog posts after post content (in FrontEnd). Short URLs are great for sharing your posts on micro-blogging sites like twitter, identi.ca etc., This plugin sends current post or page URL to <a href="https://v.gd" rel="nofollow ugc">v.gd</a> or <a href="https://tinyurl.com" rel="nofollow ugc">TinyURL.com</a> and gets a short URL for the same. Then it shows that Short URL after post content. You can select which users can see short URL textbox: “All users”, “Regitered users” or “Registered users that can edit the post/page”. User can just click on the box to select URL, or click on a Copy button to Copy the Short URL to clipboard. You can also show Short URLs for pages by selecting Show Short URL FE on pages option in plugin settings page.

<h4>How to style the output?</h4>
You can add a class for textbox and a class for button on Short URL FE plugin options page.

<pre><code>/* this change background color for area where plugin is shown */
.short-url-fe {
 background-color: #ccc;
 padding: 4px;
 border-radius: 4px;
}
/* Assuming you added a class 'mytextbox' for textbox, this adjusts textbox style */
.short-url-fe .mytextbox {
 width: min(20rem, 70%);
 box-shadow: 2px 2px 4px 1px #ccc inset;
 padding: .5rem 4px;
