HTML Formatting

HTML has special tags to format text, for example to make it bold, italic or highlighted. Some tags only change the look, and some also give a meaning to the text.

TagMeaning
<strong>Important text (bold)
<b>Bold text, without extra importance
<em>Emphasised text (italic)
<i>Italic text, like a technical term or thought
<mark>Highlighted text
<small>Smaller text, like a note
<del>Deleted text (line through)
<ins>Inserted text (underline)
<sub>Subscript
<sup>Superscript
<code>Computer code
<abbr>Abbreviation, with the full form in title
<q>, <blockquote>Short and long quotations

Example

<p>Water is H<sub>2</sub>O and 5<sup>2</sup> is 25.</p>

<p><abbr title="HyperText Markup Language">HTML</abbr> is easy.</p>

He said: HTML is the base of the web.

A longer quotation goes in a blockquote element.


strong vs b, and em vs i

Visually they look the same, but strong and em tell the browser and screen readers that the text is important or emphasised. So prefer strong and em for normal text.

Note: Tags like <font>, <big>, <strike> and <tt> are removed from HTML5. Use CSS.

Summary

  • Use strong and em for importance and emphasis.
  • Use mark, del, ins, sub, sup and code for special text.
  • Use q and blockquote for quotes.
