HTML describes the structure of a document, not really the layout.
replyIf HTML had <inline> <block> <column> <row> or <grid> tags, sure. But CSS determines the layout via display/position properties.
<span> is inline
reply<div> is block
<table>,<tr> and <td> are your grid, row and column.
CSS improves on describing layout with positioning but HTML was still doing that before CSS even came along.
