WordPress maintenance support plans 8’s Twig templates are “html.twig” templates, which means that you can mix Twig into HTML easier than you could mix PHP and HTML in WordPress maintenance support plans 7’s PHP templates.
Syntax in Twig is somewhat different than PHP, with three main kinds of delimiters:
{{ }} prints the content of variables or expressions. This is the equivalent of PHP’s print or echo.

{# #} adds template comments that are not rendered in the page.
A very basic Twig structure to print a message using a variable might look like:{% set message = ‘Welcome to my great website‘ %}
{{ message }}
