2.2: More HTML Elements

ul represents a bulleted list of items (block)
li represents a single item within the list (block)

  <li>No shoes</li>
  <li>No shirt</li>
  <li>No problem!</li>

More about unordered lists

  <li>Family Guy:

Ordered list: <ol>

ol represents a numbered list of items (block)

<p>RIAA business model:</p>
  <li>Sue customers</li>
  • we can make lists with letters or Roman numerals using CSS (later)

Definition list: <dl>, <dt>, <dd>

dl represents a list of definitions of terms (block)
dt represents each term, and dd its definition

  <dt>newbie</dt> <dd>one who does not have mad skills</dd>

Quotations: <blockquote>

<p>As Lincoln said in his famous Gettysburg Address:</p>
  <p>Fourscore and seven years ago, our fathers brought forth

    dedicated to the proposition that all men are created equal.</p>

Inline quotations: <q>

a short quotation (inline)

<p>Quoth the Raven, <q>Nevermore.</q></p>

We don't use " marks for two reasons:

  1. HTML shouldn't contain literal quotation mark characters; they should be written as &quot;
  2. using <q> allows us to apply CSS styles to quotations (seen later)

HTML Character Entities
