Header element
Header element contains summary information about the document, also called meta-information. Meta means "information about something".
It can be said that meta-data is information about data, and meta-information is information about information.
Information within the header element
Elements within the header element will not be displayed by the browser.
According to the HTML standard, only a few tags are legal in the head section of HTML. They are: , , ,
, <style> and <script>. </p>
<p>This is an illegal structure: </p>
<p><head><br> <p>This is some text</p><br></head>In this case , the browser has two options: </p>
<p> Display the text as it is within a paragraph element. <br>Hidden text because it is in the header element. <br>If you place an HTML element like <h1> or <p> inside a header element like this, most browsers will display it, even though it's illegal. </p>
<p>Should browsers really ignore this error? We don't think so. Even if others think so. </p>
