A nice concept of separated text in a box! Lets make it a bit more modern:
Biggest problem I see here horizontal line. Not line but its color. If we would use standard wiki markup we can not change its color. It appears at highest level.. Then it is there no more:
111111
2222222
3333333
That's why I would consider using an alternative approach.
No HTML table here, only CSS! Tables are used for grid-ish layout. On our wiki is it not often used but there are some features were it is used as 'mark plates': Template: Homin
A text box with an border. dn-text-box
This page should be attractive enough to invite people to read its content as informative as possible.
