e.nigma buttons is a lightweight plugin that adresses a common problem that applies to many WordPress users: Visually highlight a link (e.g. a download link). One great solution is the use of buttons
The purpose of a button is clear. You press that button and something happens. This is a well known principle that most users are aware of. In contrast to regular text links (e.g. a download link), buttons are more likely to be noticed, especially if you use them in combination with an icon.
e.nigma buttons allows you to easily create those visually attractive buttons using a simple shortcode environment.
Development of the plugin is an open process. The current version is available on github:
https://github.com/chemiker/enigma-buttons
Feel free to contribute and to fix errors or send improvements via github.
<h3>Shortcodes & Attributes</h3>
e.nigma buttons adds the shortcode <code>[button]</code> to your installation. The following options can be used to adjust the button for your needs:
<ul>
<li><code>label</code>: The label of your button</li>
<li><code>icon</code>: The icon of your button</li>
<li><code>link</code>: The link of your button</li>
<li><code>color</code>: The color of button</li>
<li><code>border</code>: yes (default) or no</li>
<li><code>size</code>: small, medium (default) or large</li>
<li><code>class</code>: Additional CSS classes that will be added to your buttons icon</li>
</ul>
Most of the shortcodes attributes are self explaining. However, it must be noted that the <code>icon</code> attribute can be filled by using modififed <a href="http://fontawesome.io/icons/" rel="nofollow ugc">Font Awesome shortcodes</a>.
For instance: If you want to use the GitHub icon you would search for that icon in the <a href="http://fontawesome.io/icons/" rel="nofollow ugc">list of all icons</a>. What you will find is the corresponding CSS class. For e.nigma buttons the name of the icon (which is obtained if stripping the “fa-” in the beginning of the CSS class) is used. For GitHub the CSS class would be <code>fa-github</code>. Thus, <code>github</code> is your value for the <code>icon</code> attribute.
<h4>Colors</h4>
The following colors are avaible: 
* green 
* orange 
* purple 
* cyan 
* white 
* red 
* black
In addition to those values you can also use a hex color code (e.g. #ff3600)
<h4>Icons</h4>
e.nigma buttons uses <a href="http://fontawesome.io/" rel="nofollow ugc">Font Awesome</a> by Dave Gandy as icon resource. <a href="http://fontawesome.io/icons/" rel="nofollow ugc">An overview over all available icons</a> can be found on their website.
<h4>Examples</h4>
<pre><code>[button label="My GitHub account" icon="github" color="orange" link="https://github.com/chemiker"]
</code></pre>
Brings you an linked, medium-sized, orange button that has a GitHub icon and the label “My GitHub account”.
<pre><code>[button icon="github" color="orange" link="https://github.com/chemiker" size="large"]
</code></pre>
Brings you an orange, large-sized, linked GitHub icon.

Block: Icons Font Awesome adds a single, focused Icon block to the WordPress block editor (Gutenberg). Pick from roughly 2,000 free Font Awesome 6 icons and drop them anywhere — no shortcodes, no page builder, no coding.
Icons render as inline SVG, so your site never loads the Font Awesome webfont or an extra stylesheet just to show an icon. That keeps pages fast and the markup clean.
<h4>Features</h4>
<ul>
<li>~2,000 free Font Awesome 6 icons — Solid, Regular, and Brands.</li>
<li>Full-screen icon picker with instant search (by name and keyword), a category sidebar with per-style counts, a style filter, and a “recently used” list.</li>
<li>Inline SVG output — no webfont, no render-blocking icon CSS.</li>
<li>Styling controls — color, hover color, size, and alignment.</li>
<li>Link support — wrap the icon in a link, optionally opening in a new tab.</li>
<li>Accessibility — mark an icon as decorative (hidden from screen readers) or give it a label; links always get an accessible name.</li>
<li>Global defaults — a Settings page to set the default style, size, and color, and to choose which icon styles appear in the picker.</li>
</ul>
