Q is for Quote <q>
The quote element seems to be a hangover from the days when the internet
was the preserve of academics exhanging learned papers.
Many academic papers will have quotations, and so it's no surprise
that a quote element exists. This <q> is actually the one for a short
quotation, and doesn't actually do any formatting to the enlcosed text!
That has to be done with other styling. So on its own its changes nothing.
If you want to indent a long quotation then you should use the <blockquote>
element.
HTML elements can be divided into two general levels: inline
and block. Block level (e.g. <p>) are displayed as blocks and have
line breaks before and after them.
Inline elements (e.g. <font>) are applied or displayed in
line.
The <q> tag is an inline element while the <blockquote> is a block
element.
