In HTML, quotation tags are used to mark quoted content in documents, including block-level quotes (<blockquote>) and inline quotes (<q>). They not only semantically annotate the source of content but can also achieve rich visual effects through CSS.

<blockquote> Tag

<blockquote> is used to define long quotations, typically as standalone block-level elements. Browsers default to adding left and right indentation styles. The cite attribute can specify the URL of the quotation source, though it won't be displayed directly on the page.

<blockquote cite="https://example.com/source">
  <p>This is an independent block-level quote, usually used for large quoted passages.</p>
</blockquote>

The actual display will appear as an indented paragraph. Combined with CSS, more complex styles can be created:

<style>
  blockquote {
    border-left: 4px solid #ccc;
    padding-left: 1em;
    margin-left: 0;
    font-style: italic;
    color: #555;
  }
</style>

<blockquote>
  <p>Design is not just what it looks like or feels like. Design is how it works.</p>
  <footer>— Steve Jobs</footer>
</blockquote>

<q> Tag

<q> is used for short inline quotations. Browsers automatically add quotation marks (which can be modified via CSS). It also supports the cite attribute:

<p>As the saying goes, <q cite="https://example.com/quote">Knowledge is power</q>, learning never ends.</p>

Different browsers may render quotation marks differently, but CSS can standardize them:

q {
  quotes: "「" "」" "『" "』";
}
q:before {
  content: open-quote;
}
q:after {
  content: close-quote;
}

Nested Quotations

Both tags support nesting, making them suitable for scenarios like comment replies:

<blockquote>
  <p>I think this solution is feasible</p>
  <blockquote>
    <p>I agree with this view but need to add that <q>the devil is in the details</q></p>
  </blockquote>
</blockquote>

Semantics and SEO

Proper use of quotation tags enhances page semantics:

• Screen readers recognize these tags
• Search engines parse the cite attribute for sources
• Structured data becomes clearer

<blockquote itemscope itemtype="https://schema.org/Quotation">
  <p itemprop="text">Stay hungry, stay foolish.</p>
  <footer itemprop="author">Steve Jobs</footer>
</blockquote>

Practical Application Examples

Application in a blog comment system:

<article class="comment">
  <blockquote>
    <p>This article is very enlightening</p>
    <footer>User A <time datetime="2023-01-15">January 15</time></footer>
    
    <div class="replies">
      <blockquote>
        <p>I particularly agree with the part about CSS</p>
        <footer>User B <time datetime="2023-01-16">January 16</time></footer>
      </blockquote>
    </div>
  </blockquote>
</article>

Combining with JavaScript to dynamically generate quotes:

document.getElementById('quote-btn').addEventListener('click', () => {
  const selection = window.getSelection();
  if (selection.toString()) {
    const quote = document.createElement('blockquote');
    quote.textContent = selection.toString();
    document.getElementById('comments').appendChild(quote);
  }
});

Browser Compatibility Notes

While modern browsers support these tags, note the following:

• IE7 and below require special styling
• Mobile browsers may modify default styles
• Print styles may need separate adjustments

/* Compatibility for older IE */
blockquote {
  display: block;
  margin: 1em 40px;
}

Extended Uses of Quotation Tags

Combining with <figure> and <figcaption> creates captioned quotes:

<figure>
  <blockquote>
    <p>The greatest danger for most of us is not that our aim is too high and we miss it, but that it is too low and we reach it.</p>
  </blockquote>
  <figcaption>— Michelangelo</figcaption>
</figure>

Corresponding syntax in Markdown:

> This is a blockquote in Markdown
> Can be written across multiple lines

Creative Styling for Quotes

Various visual effects can be achieved with CSS:

<style>
  .fancy-quote {
    position: relative;
    padding: 2rem;
  }
  .fancy-quote:before {
    content: """;
    font-size: 5rem;
    position: absolute;
    left: 0;
    top: 0;
    line-height: 1;
    color: rgba(0,0,0,0.1);
  }
</style>

<blockquote class="fancy-quote">
  <p>The secret to creativity is knowing how to hide your sources</p>
</blockquote>
