<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>
