Sure!
If you have a basic understanding of HTML, then this will be easy. If not, it might take time to wrap your head around it, but bear with me.
Any text that you want to display as code you have to enclose it in ‹code› tags.
Example: Let’s say you want to take the following statement: “I am 23 years old”, and ‘codify’ the number ’23’ so it is displayed as code. So immediately before the ’23’ you have to type in an Opening Code Tag (‹code›) and immediately after the ’23’ you have to type in a Closing Code Tag (‹/code›). As you probably noticed, the difference between the opening tag and the closing tag is the forward slash (/) immediately before the tag name.
So what you basically did is enclosed the number ’23’ in (‹code›) tags.
So it will look like this: I am ‹code›23‹/code› years old. But when you submit the post, these tags or omitted from the actual text in your post, and instead you see the predefined code formatting on all the text that you enclosed in the ‹code› tags. So it will look like this by the rest of the world: I am 23 years old.
I hope I was clear enough, if not feel free to ask me.
