<p>This plugin adds a Visual Subtitle field to all post, page and custom post types that have support for a title, and that use the Classic Editor. It doesn’t work with the Block Editor.</p>
<p>It allows you to include a string of text that will still be part of the post title, but be wrapped in a <code>span</code> tag, giving something like:</p>
<pre><code><h1>Visual Subtitle<span class="subtitle"></span></h1>
</code></pre>
<p>Keeping it as part of the main level 1 or two heading, means it maintains as much keyword SEO importance as the main title, yet can be given a style (in your own theme) of <code>display: block;</code> to make it visually appear as a subtitle.</p>
<p>The visual subtitle is appended to to the title on on the Posts screen, separated with a pipe (<code>|</code>) character, and appended to the title part of the document title with a colon (<code>:</code>) character.</p>

Visual Subtitle

Allows part of a post title to be styled as a subtitle. It is still within the title heading, but is wrapped in a span to be styled differently.

<p>Epitome Subtitle adds a subtitle field in the edit page of a regular post and static page. Note that a small coding is required to display the subtitle in the right location of your template. You provide to your theme the ability to display a title and a subtitle using functions that you call from your template.</p>
<h4>Functions</h4>
<ul>
<li><code>the_subtitle()</code> takes the current post or page ID and outputs the subtitle.</li>
<li><code>get_the_subtitle($post_id)</code> has one optional parameter (post or page ID) and returns the subtitle as a string.</li>
<li><code>has_post_subtitle($post_id)</code> has one optional parameter (post or page ID) and checks whether a subtitle exists.</li>
</ul>


Epitome Subtitle

Add a subtitle to regular post and static you display with a set of functions from your template.
