<h1>Basic HTML Tags</h1>
<a href="html_elements.asp"><img border="0" src="../images/btn_previous.gif" width="100" height="20" alt="Previous" /></a>
<a href="html_attributes.asp"><img border="0" src="../images/btn_next.gif" alt="Next" width="100" height="20" /></a>
<hr />
<p class="intro">The most important tags in HTML are tags that define
headings, paragraphs and line breaks.</p>
<p class="intro">The best way to learn HTML is to work with examples. We
have created a very nice HTML editor for you. With this editor, you can edit the
HTML source code if you like, and click on a test button to view the result.</p>
<hr />
<h2>Try it Yourself - Examples</h2>
<p><a target="_blank" href="tryit.asp@filename=tryhtml_basic">A very simple HTML document</a><br />
This example is a very simple HTML document, with only a minimum of HTML tags.
It demonstrates how the text inside a body element is displayed in the
browser. </p>
<p><a target="_blank" href="tryit.asp@filename=tryhtml_paragraphs1">Simple paragraphs</a><br />
This example demonstrates how the text inside paragraph elements is displayed
in the browser.
</p>
<p>(You can find more examples at the bottom of this page)</p>
<hr />
<h2>Headings</h2>
<p>Headings are defined with the <h1> to <h6> tags. <h1>
defines the largest heading. <h6> defines the smallest heading.</p>
<table width="100%" class="ex" cellspacing="0" border="1">
<tbody>
<tr>
<td>
<pre><h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
<h4>This is a heading</h4>
<h5>This is a heading</h5>
<h6>This is a heading</h6></pre>
</td>
</tr>
</tbody>
</table>
<p>HTML automatically adds
an extra blank line before and after a heading.</p>
<hr />
<h2>Paragraphs</h2>
<p>Paragraphs are defined with the <p> tag.</p>
<table width="100%" class="ex" cellspacing="0" border="1">
<tbody>
<tr>
<td>
<pre><p>This is a paragraph</p>
<p>This is another paragraph</p></pre>
</td>
</tr>
</tbody>
</table>
<p>HTML automatically adds
an extra blank line before and after a paragraph.</p>
<hr />
<h2>Don't Forget the Closing Tag</h2>
<p>You might have noticed that paragraphs can be written without end tags </p>:</p>
<table width="100%" class="ex" cellspacing="0" border="1" id="table1">
<tbody>
<tr>
<td>
<pre><p>This is a paragraph
<p>This is another paragraph</pre>
</td>
</tr>
</tbody>
</table>
<p>The example above will work in most browsers, but don't rely on it. Future version of HTML will not allow you to
skip ANY end tags.</p>
<p>Closing all HTML elements with an end tag is a future-proof way of writing
HTML. It also makes the code easier to understand (read and browse) when you
mark both where an element starts and where it ends. </p>
<hr />
<h2>Line Breaks</h2>
<p>The <br> tag is used when you want to break a line, but don't want to start a new
paragraph. The <br> tag forces a line break wherever you place it.</p>
<table width="100%" class="ex" cellspacing="0" border="1">
<tbody>
<tr>
<td>
<pre><p>This <br> is a para<br>graph with line breaks</p></pre>
</td>
</tr>
</tbody>
</table>
