Can I bold description meta tag?

Question

Can I format meta tags like this, especially og tag, because I want bold text inside facebook share window.

<meta name='description' content='<strong>WELCOME TO MY NEXT PERFORMANCE</strong>'>
<meta property='og:description' content='<strong>WELCOME TO MY NEXT PERFORMANCE</strong>'>

Answer 1

The content of the attributes of a meta tag is by definition just text: no tags are recognized (though character references are parsed). So the example is valid, but this is just a formality. All the rest depends on software that interprets meta tags. It would however be odd to treat its attributes as anything but plain text.

(AND I THINK SHOUTING IS QUITE SUFFICIENT FOR MAKING THE TEXT LOOK FOOLISH, YOU DO NOT NEED TO BOLD IT.)
