Can i create a infobox with any default code in a page or post?

Hi there,

Can you provide an example of what you'd like to achieve?

Like this demo https://sv.wordpress.org/themes/twentyeleven/ and scroll down to the heading "Misc Stuff - abbr, acronym, pre, code, sub, sup, etc."

Yup you should be able to create something exactly like that using GP Premium.

This would be your content:

<h2>Misc Stuff – abbr, acronym, pre, code, sub, sup, etc.</h2>
