    Catch a block of code separated by 4 four backticks (as the markdown syntax).
    


    Example to be adapted easily.
    


    ]*(.*?)````/';

preg_match($reg, $str, $matches);
echo $matches[0];

/* OUTPUT
```` 
    h5 {
      font-size: 1rem;
      font-weight: 600;
    }
````
*/

echo preg_replace($reg, "DELETED", $str);

/* OUTPUT
# Some Text

DELETED

And some text.
*/
