Update meta property for URL link in header.php

Hello,

I am using your Royal theme and I would like your advice on the best way to adjust meta property for when my URL is posted in social media platforms such as facebook. I would normally add the following code into the header.php file,

<meta property=”og:image” link=”http://www.etc”/&gt;

<meta property=”og:title” content=”This will be the title displayed!” /><meta property=”og:description” content=”This will be the description that shows below the title!” />

however as this theme uses theme options framework, I want to know if it is advised to make changes by adding custom css code through theme options panel, or straight into the header.php file as normal?

I look forward to your reply.

Thank you
