#HTML's formatting tags

HTML formatting elements are designed to display special types of text:

• <span> – Custom formatting; does not change style by itself
• <b> – Bold text
• <strong> – Important text
• <i> – Italic text
• <em> – Emphasized text
• <mark> – Marked text (highlighted)
• <small> – Smaller text
• <del> – Deleted text (strikethrough)
• <ins> – Inserted text (underlined)
• <sub> – Subscript text
• <sup> – Superscript text

Example:

<p> Paragraph <span> custom formatting </span> </p>
<p> Paragraph <b> bold text </b> </p>
<p> Paragraph <strong> important text </strong> </p>
<p> Paragraph <i> italic text </i> </p>
<p> Paragraph <em> emphasized text </em> </p>
<p> Paragraph <mark> marked text </mark> </p>
<p> Paragraph <small> smaller text </small> </p>
<p> Paragraph <del> deleted text </del> </p>
<p> Paragraph <ins> inserted text </ins> </p>
<p> Paragraph <sub> subscript text </sub> </p>
<p> Paragraph <sup> superscript text </sup> </p>
