I donÂ´t get any wrong message

I jon,

Thanks for the possibility your give us to ask question about your book or the topic

I take your for a week in the library from my University.My goal is start learning web design.

I have the problem that your explain something from the first example (ch01_eg01.htm).
at page 6 you said:

If you want to have one element inside another, then both the elementâs opening and closing tags must be
inside the containing element. For example, the following is allowed:

This paragraph contains some emphasized text.

Whereas the following is wrong because the closing

tag is not inside the paragraph element:

This paragraph contains some emphasized text. 

the point is when I try the wrong version itÂ´s walk.I donÂ´t get any wrong message from explorer or mozilla.
I don`t know more what wrong or what right.
I use internet explorer 8 and firefox 3.6.2

I repeat when I tested I donÂ´t get any error message.when I move the <html> tag from the code.IT WALK.It shouldnÂ´t normally.

regard

Alain

You didn't see any warnings or errors, because the browsers are very tolerative. Try to validate the following with W3C validation service: http://validator.w3.org/, and you will see the warnings and errors:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 
    <title>Title</title>
</head>
<body>
<p> This paragraph contains some <em>emphasized text. </p></em>
</body>
</html>

Thank you Peter .
I was a little bit frustrate and spent one day trying to understand this situation.I havenÂ´t try the validator from W3C but I know it is probably what you say.It means if I have old version from firefox or explorer.It will catch the errors.

thank you again

A Bientot

Alain
