Editing HTML (section)

===== Headings =====
HTML headings are defined with the {{code|lang=html|code=<h1>}} to {{code|lang=html|code=<h6>}} tags with H1 being the highest (or most important) level and H6 the least:
<syntaxhighlight lang="html">
<h1>Heading level 1</h1>
<h2>Heading level 2</h2>
<h3>Heading level 3</h3>
<h4>Heading level 4</h4>
<h5>Heading level 5</h5>
<h6>Heading level 6</h6>
</syntaxhighlight>
The effects are:
<blockquote>
<div style="overflow: hidden; page-break-after: avoid; font-size: 1.8em; font-family: Georgia,Times,serif; margin-top: 1em; margin-bottom: 0.25em; line-height: 1.3; padding: 0; border-bottom: 1px solid #AAAAAA;">Heading Level 1</div>
<div style="overflow: hidden; page-break-after: avoid; font-size: 1.5em; font-family: Georgia,Times,serif; margin-top: 1em; margin-bottom: 0.25em; line-height: 1.3; padding: 0; border-bottom: 1px solid #AAAAAA;">Heading Level 2</div>
<div style="overflow: hidden; page-break-after: avoid; font-size: 1.17em; font-weight: bold; margin-top: 0.3em; margin-bottom: 0; line-height: 1.6; padding-top: 0.5em; padding-bottom: 0;">Heading Level 3</div>
<div style="overflow: hidden; page-break-after: avoid; font-size: 100%; font-weight: bold; margin-top: 0.3em; margin-bottom: 0; line-height: 1.6; padding-top: 0.5em; padding-bottom: 0;">Heading Level 4</div>

<div style="overflow: hidden; page-break-after: avoid; font-size: 100%; font-weight: bold; margin-top: 0.3em; margin-bottom: 0; line-height: 1.6; padding-top: 0.5em; padding-bottom: 0;">Heading Level 6</div>
