Head First HTML with CSS

making your html strict
Changing the DOCTYPE to strict
Open your “lounge.html” file again. To change from transitional to
strict, you just need to do two things to the DOCTYPE: delete the word
“Transitional” and, in the URL, change “loose.dtd” to “strict.dtd”. Or if
you like, you can delete the old line and type the new one in.

First, remove the word
“Transitional”.
That’s it. Just make sure your DOCTYPE looks exactly as it does above.
Now all that remains is to ask the validator if our HTML is compliant with
the strict version of HTML 4.01. Use the validator again to check the page,
after making sure your page has the changes above.
And then replace “loose.dtd” with “strict.dtd”.
