This plugin removes font-family, font-size, font-weight, line-height and color declarations from existing content.
This can be useful if you have published posts and pages with out of date styling. It also removes unwanted styles that may appear when copy and pasting from Microsoft Word or other text editors.

Add Typography to your Gutenberg site using Google Fonts. Enter CSS selectors or select Blocks to apply custom typography.
<h3>Typography style</h3>
Available typography options include:
<ul>
<li>Font family & variants from Google Fonts</li>
<li>Color (hex or rgba)</li>
<li>Font size</li>
<li>Line height</li>
<li>Font weight</li>
<li>Font style (italic, normal, oblique)</li>
<li>Letter spacing</li>
<li>Text transform (capitalize, uppercase, lowercase)</li>
<li>Text decoration (line-through, overline, underline)</li>
</ul>
<h3>Typography context</h3>
Typographies can be assigned to a specific context:
<ul>
<li>All site</li>
<li>Post types/s (post types available on the site)</li>
<li>Post types/s template (index, single)</li>
<li>Front page</li>
<li>404 page</li>
</ul>
<h3>Typography selectors</h3>
Each typography can have several groups of selectors with unique modifications based on the root typography. 
For example: a typography can be set with a certain Font, Color and Font size; 
each of its groups of selectors inherit those properties and one could modify the inherited color and other the inherited Font size.
Available CSS selectors include:
<ul>
<li>Text CSS selector (eg: .site-title a)</li>
<li>Block Selector (eg: Block Quote > Citation)</li>
</ul>
<h3>Usage</h3>
The plugin can be accesed from the Customizer inside the tab The Typography. 
It can also be accesed from any Block editor’s The Typography sidebar (top right corner of the editor). 
Create a typography and assign it some options; create a group of selectors and inside it create some CSS or Block selectors. 
That’s it! 
If you want to preview the different fonts before selecting one you can preview them in the <a href="https://fonts.google.com/" rel="nofollow ugc">Google Fonts repository</a>. 
Note: The typography editing is assigned to the ‘edit_theme_options’ capability. This means that, by default, only admin and super admin will be able to use the features.
