The Text Module declares the core text elements, within four support modules.
The elements div and
span are merely block and inline containers,
respectively, and have no other semantic meaning. The
br element is used to insert a line break into
a section of inline text and pre is used to preserve
whitespace within a block of text. Other elements in this module have clear semantic meanings and
should be used only where that meaning is appropriate and not merely for visual purposes, e.g. the headings
h1 - h6 should
not be used merely to increase the font size of text which is not actually a heading.
