What does header mean?

1: What does header mean?

Header is a structural element with navigation function, which may contain some title elements and other elements. Such as search form, navigation, logo, etc., the header element that generally appears at the top of the page or near this position becomes the header of the entire page.

2: How to use header

If a page contains multiple content blocks, you can add a header element to each content block. In other words, a page can have Any number of header elements, their meaning can vary depending on context.

The

element has no sliced content and therefore does not introduce a new section outline, that is, a

element usually contains the surrounding section headers (h1-h6), Of course, you should only use header elements when necessary. In most cases, if using h1~h6 can meet the needs, there is no need to wrap them with header. You cannot nest a footer or another header element within a header, nor can you nest a header element within a footer or address element. For example:

<body>
<header>
<nav>
<ul>
<li><a href="http://www.php.cn/">php中文网</a>
<li><a href="http://www.php.cn/">php中文网</a>
<li><a href="http://www.php.cn/">php中文网</a>
</ul>
</nav>
<h1 id="php中文网">php中文网</h1>
<h2 id="php中文网">php中文网</h2>
<p>php中文网</p>
<h2 id="php中文网">php中文网</h2>
<p>php中文网</p>
</header>
</body>

Using ID selectors is not inherently bad in CSS, but should be used with caution. 1) ID selector is suitable for unique elements or JavaScript hooks. 2) For general styles, class selectors should be used as they are more flexible and maintainable. By balancing the use of ID and class, a more robust and efficient CSS architecture can be implemented.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
