Logical vs. Physical Tags
In HTML there are both logical tags and physical tags. Logical tags are designed to describe (to the
browser) the enclosed text's meaning. An example of a logical tag is the tag. By
placing text in between these tags you are telling the browser that the text has some greater
importance. By default all browsers make the text appear bold when in between the and
tags.
Physical tags on the other hand provide specific instructions on how to display the text they enclose.
Examples of physical tags include:
: Makes the text bold.
: Makes the text usually one size bigger than what's around it.
: Makes text italic.
Physical tags were invented to add style to HTML pages because style sheets were not around, though
the original intention of HTML was to not have physical tags. Rather than use physical tags to style
your HTML pages, you should use style sheets.
