The general format of a BBCode has three parts, an opening tag, the inside content and a closing tag, as shown below:
[open] text inside [/close] [b] bold text [/b]
Bold and italic text
You can place one BBCode tag inside another as long as the child tag is closed before the parent tag. For example, the correct way to make bold and italic text is:
[b][i]bold & italic text[/i][/b]
You can also do it this way both are valid ways, just the tags are in reverse order.
[i][b]bold & italic text[/b][/i]
This is shown more easily when the tags are indented:
[b] [i] bold & italic text [/i] [/b]
The next example is incorrectly nested, which is easily shown with indented tags:
[b][i]bold & italic text[/b][/i] [b] [i] bold & italic text [/b] [/i]
The Size Tag
Note that the order in which the size tag is nested is important when it is paired with following text alignment tags center, left, right, and pre tags. For the size tag to change the font, it must be placed as follows:
Nesting the size tags as per the example below will result in this tag not working.
