Paragraphs
Syntax
<p>Text content here.</p>
Example
<p>Our platform processes over two million transactions daily.</p><p>Each transaction is encrypted end-to-end for security.</p>
Note Browsers add default top and bottom margins to paragraphs. Reset or adjust with CSS if needed.
<p><strong>Warning:</strong> This action <em>cannot</em> be undone.</p>
Note strong conveys urgency or importance (renders bold). em conveys stress emphasis (renders italic). Prefer these over <b> and <i> for meaningful emphasis, since screen readers alter vocal tone for strong/em.
<blockquotecite="https://example.com/speech"><p>The only limit to our realization of tomorrow is our doubts of today.</p></blockquote>
Note The cite attribute provides the source URL but is not displayed by browsers. Add visible attribution separately if needed.

Syntax
<pre><code>code here</code></pre>
Example
<pre><code>function greet(name){
return `Hello, ${name}!`;}</code></pre><p>Use <code>Array.map()</code> to transform items.</p>
Note pre preserves all whitespace and line breaks exactly as written. Wrap code inside pre for multi-line blocks. Use code alone for inline code snippets.
<p>123 Main Street<br>Suite 400<br>Springfield, IL 62704</p><hr><p>New section begins here.</p>
Note br is for meaningful line breaks like addresses or poetry, not for spacing. Use CSS margins or padding for spacing. hr represents a thematic shift between content blocks.
