Within the HTML example, first replace the "&" character with "&amp;" everywhere it occurs. Then replace the "&lt;" character with "<" and the "&gt;" character with ">" in the same way. Note that it may be appropriate to use the CODE and/or PRE elements when displaying HTML examples.

To replace special characters in HTML, you can use their corresponding HTML entities. Here's an example of how you can replace the "&", "&lt;", and "&gt;" characters in HTML:

```html
<code>
  &amp;lt;p&amp;gt;Hello, World!&amp;lt;/p&amp;gt;
</code>
```

In this example, the "&" character is replaced with "&amp;amp;", the "&lt;" character is replaced with "<", and the "&gt;" character is replaced with ">". Adding the `<code>` element is a good way to display HTML examples within your document.


Here's another example, replacing the special characters in the HTML code using the appropriate HTML entities:

```html
<pre>
  &amp;amp;lt;p&amp;amp;gt;Hello, World!&amp;amp;lt;/p&amp;amp;gt;
</pre>
```

In this updated example, the "&" character is replaced with "&amp;amp;", the "&lt;" character is replaced with "&amp;lt;", and the "&gt;" character is replaced with "&amp;gt;". Wrapping the HTML code within a `<pre>` element displays it as pre-formatted text, maintaining the spacing and line breaks.


Here's a detailed explanation with step-by-step instructions on replacing special characters in HTML:

Step 1: Replace "&" with "&amp;"
Find all occurrences of the "&" character in your HTML code and replace them with "&amp;". This prevents the browser from interpreting it as the start of an HTML entity. For example:

```html
<p>This is a &amp; example.</p>
```

Step 2: Replace "<" with "&lt;"
Next, locate all instances of the "<" character and replace them with "&lt;". This ensures that the browser doesn't mistake it for an opening tag. For example:

```html
<p>This is a &amp; example. It contains &lt;strong&gt;important&lt;/strong&gt; information.</p>
```

Step 3: Replace ">" with "&gt;"
Finally, locate all occurrences of the ">" character and replace them with "&gt;". This prevents the browser from interpreting it as the closing tag of an HTML element. For example:

```html
<p>This is a &amp; example. It contains &lt;strong&gt;important&lt;/strong&gt; information.&gt;</p>
```

To display this HTML code properly within your document, you can wrap it inside the `<pre>` or `<code>` element. These elements preserve the formatting and display the text verbatim.


extended explanation with examples:

Step 1: Replace "&" with "&amp;"
Replace all occurrences of the "&" character with its corresponding HTML entity "&amp;". This ensures that the browser interprets it as a literal ampersand and not the start of an HTML entity. For example:

```html
<p>This is an example &amp; text.</p>
```

Step 2: Replace "<" with "&lt;"
Replace all occurrences of the "<" character with its corresponding HTML entity "&lt;". This tells the browser to interpret it as a literal less-than symbol and not the start of an HTML tag. For example:

```html
<p>This is an example &amp; text. It contains &lt;strong&gt;important&lt;/strong&gt; information.</p>
```

Step 3: Replace ">" with "&gt;"
Replace all occurrences of the ">" character with its corresponding HTML entity "&gt;". This ensures that the browser interprets it as a literal greater-than symbol and not the end of an HTML tag. For example:

```html
<p>This is an example &amp; text. It contains &lt;strong&gt;important&lt;/strong&gt; information.&gt;</p>
```

By following these steps, you are effectively escaping the special characters "&", "<", and ">" in your HTML code, preventing any unintended interpretations by the browser.
