Tag <sup> add automaticly

Hello. When I added a text
<li>Responsive 24/7 technical support</li>
this text replace to

<li>Responsive <sup>24</sup>⁄<sub>7</sub> technical support</li>

Why?

Because the markdown render interprets that as being a fraction. There are ways to get around it. Either remove any code indentation or change the file extension to .html instead of .md

You can turn it off, look at the blackfriday config doc (something ab out “fractions”)
