Head First HTML with CSS

html and deprecated markup
258 Chapter 6
One more question
about this transitional
stuff. What is all this old
markup that isn’t allowed in
strict? Have we seen any
examples?
No, we’ve been writing mostly
strict HTML all along.
Even though we haven’t been including a
DOCTYPE or a tag, and we’ve
been a little lazy on the image nesting rules,
throughout this book you’ve been writing
HTML that is very close to the standard. So,
you haven’t had much opportunity to see the
phased out elements and attributes.
Want to see some? Just visit a few Web pages
with your browser and choose “View Source”
from the “View” menu (your browser’s menus
may differ). Any tag or attribute that looks
like it is used to alter the display of the page is
most likely deprecated in HTML 4.01 (because
that is now CSS’s job). It doesn’t hurt to know
a little about these legacy elements, because
you are quite likely to run into some of them
now and then. Let’s take a quick look...
That’s a good thing, because
sometimes unlearning a bad
habit is the hardest part of
a new standard.
