and are used to quote content, the former is used for large segments, and the latter is used for in-line quotations, and can be marked with ; 2. <code>, <pre class="brush:php;toolbar:false"> and &lt;samp&gt; are used to display code or computer output, where &lt;code&gt; represents in-line code, &lt;pre class=&quot;brush:php;toolbar:false&quot;&gt; retains formatted line breaks, and &lt;samp&gt; represents program output results; 3. &lt;em&gt; and &lt;strong&gt; are used to emphasize text, indicating key points and higher importance respectively, the default style is italic and bold, and has a positive effect on accessibility.

 <blockquote>
  Knowledge is power.
  <cite>—— Francis Bacon</cite>
</blockquote>

<code><code> , <code>

</code> and <code><samp></code> : Process code-related text</h3><p> These three tags are used to display code or computer output content, and each has different uses:</p><ul><li> <code><code></code> : Represents a piece of programming code or command, usually an inline element</li><li> <code><pre class="brush:php;toolbar:false"></code> : Keep whitespace characters and line breaks, suitable for displaying multi-line code blocks</li><li> <code><samp></code> : represents the output result of the program</li></ul><p> Common writing methods:</p><pre class='brush:php;toolbar:false;'> <pre class="brush:php;toolbar:false"><code>
function hello() {
  console.log("Hello world");
}
</code>

Running result: Hello world

Note: If you want <code>

</code> or <code><code></code> to have syntax highlighting effects, you can combine libraries such as Prism.js or Highlight.js to achieve it.</p><h3> <code><em></code> and <code><strong></code> : Emphasize the importance of text</h3><p> Although <code><i></code> and <code><b></code> can also change the text style, they have no clear semantic meaning. The following two tags are recommended to emphasize content:</p><ul><li> <code><em></code> : Indicates the emphasis, browsers are usually presented in italics</li><li> <code><strong></code> : It means that it is more important, and the default bold display is displayed</li></ul><p> For example:</p><pre class='brush:php;toolbar:false;'> <p>Please remember to take the exam with your ID card. </p>
<p>Warning: <strong>This operation is irrevocable! </strong></p>

These semantic tags allow screen readers to make different voice prompts, which are critical to accessibility than simply using style tags.
