Question

Is it valid to have a div inside of a <td> element? I need to display a box inside of the table..

Update:

I need this box (that appears in the td) to have padding..i.e. it really needs to look like a box that’s floating in the middle of the td.

Answer 1

A div element inside a td element is perfectly valid according to the XHTML 1.0 Strict DTD.

<!ELEMENT td       %Flow;>

<!ENTITY % Flow "(#PCDATA | %block; | form | %inline; | %misc;)*">

<!ENTITY % block
    "p | %heading; | div | %lists; | %blocktext; | fieldset | table">
