Not sure why this reply keep blocking me from giving you the code snippet code. I just send you the snapshot then

Highlighting Code Snippet in an HTML Page, you often use the <pre> and <code> tags in tandem. The <pre> tag defines preformatted text and is used to display text as it's written in the HTML source code. The <code> tag defines a piece of computer code and is often used inside the <pre> tag to preserve both whitespace and line breaks.

For example:

Refer to attahment

With this setup, a copy button will appear when you hover over the code snippet, and clicking the button will copy the code to your clipboard.
