Bulletin board code/eo

Bulletin board codes or BBCodes are a way to format posts in SMF and in many other places online. For an explanation of the buttons in the post page, see Basic Bulletin Board Codes. This article explains the important concept of nesting.

Nesting BBCodes
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]

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]
