HTML - Hypertext Markup Language, the brainchild of legendary Tim Berners-Lee, describes the static content of a web page.
Semantics over aesthetics
And the key word is content.
Just say "no."
And while you're at it, structure the data according to its meaning, not desired appearance. Use <ul> for lists of data, <dl> for definition lists, <table> for tables of data, and <label>.
Don't shy away from <fieldset>s and <legend>s, nor <caption>s for your <table>s.
(Many online tutorials exist for each of these, and are not duplicated here.)
This will make your pages sleek and concise, and more accessible to the world, especially screen readers and other non-standard devices.
