HTML contains several elements for defining text with a special meaning.
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p><b>This text is bold</b></p>
<p><i>This text is italic</i></p>
<p>This is<sub> subscript</sub> and <sup>superscript</sup></p>
</body>
</html>
Formatting elements were designed to display special types of text:
<b> - Bold text
<strong> - Important text
<i> - Italic text
<em> - Emphasized text
<mark> - Marked text
<small> - Smaller text
<del> - Deleted text
<ins> - Inserted text
<sub> - Subscript text
<sup> - Superscript text
The HTML <b> element defines bold text, without any extra importance.
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This text is normal.</p>
<p><b>This text is bold.</b></p>
</body>
</html>
The HTML <strong> element defines text with strong importance. The content inside is typically displayed in bold.
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This text is normal.</p>
<p><strong>This text is important!</strong></p>
</body>
</html>
The HTML <i> element defines a part of text in an alternate voice or mood. The content inside is typically displayed in italic.
Tip: The <i> tag is often used to indicate a technical term, a phrase from another language, a thought, a ship name, etc.
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This text is normal.</p>
<p><i>This text is italic.</i></p>
</body>
</html>
The HTML <em> element defines emphasized text. The content inside is typically displayed in italic.
Tip: A screen reader will pronounce the words in <em> with an emphasis, using verbal stress.
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This text is normal.</p>
<p><em>This text is emphasized.</em></p>
</body>
</html>
The HTML <small> element defines smaller text:
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This is some normal text.</p>
<p><small>This is some smaller text.</small></p>
</body>
</html>
The HTML <mark> element defines text that should be marked or highlighted:
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>If there is a <mark>hole,</mark> there is a <mark>goal.</mark> </p>
</body>
</html>
The HTML <del> element defines text that has been deleted from a document. Browsers will usually strike a line through deleted text:
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>Your grade is over <del>95</del> 85.</p>
</body>
</html>
The HTML <ins> element defines a text that has been inserted into a document. Browsers will usually underline inserted text:
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>Your grade is over <del>95</del> <ins> 85</ins>.</p>
</body>
</html>
The HTML <sub> element defines subscript text. Subscript text appears half a character below the normal line, and is sometimes rendered in a smaller font. Subscript text can be used for chemical formulas, like H2O:
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This is <sub>subscripted</sub> text.</p>
</body>
</html>
The HTML <sup> element defines superscript text. Superscript text appears half a character above the normal line, and is sometimes rendered in a smaller font. Superscript text can be used for footnotes, like WWW[1]:
EXAMPLE:
<!DOCTYPE html>
<html>
<body>
<p>This is <sub>subscripted</sub> text.</p>
</body>
</html>
