Html code for program block
In HTML, there is no specific "program block" element. However, you can use the <code> and <pre> tags to create a block of code that is displayed exactly as it is written, without any formatting applied. Here's an example:
<pre>
<code>
// This is a JavaScript program
let greeting = "Hello, world!";
console.log(greeting);
</code>
</pre>
<pre><code></code></pre>
In the above code, the <pre> tag creates a block-level element that preserves all whitespace and line breaks inside it. The <code> tag is nested inside the <pre> tag and contains the actual code. By using both tags together, we can display the code in a block format while preserving its formatting.
Alternatively, you can also use <div> or <section> tags to create a program block and then use CSS styling to format it accordingly. Here's an example:
<section class="program-block">
  <h2>JavaScript Program</h2>
  <pre>
    <code>
      let greeting = "Hello, world!";
      console.log(greeting);
    </code>
  </pre>
</section>
<style>
  .program-block {
    background-color: #f5f5f5;
    padding: 10px;
    border-radius: 5px;
    font-family: monospace;
  }
  .program-block h2 {
    font-size: 1.2em;
    margin-bottom: 10px;
  }
</style>
In the above code, we've created a <section> element with a class of "program-block" to contain our program. We've also added some CSS styles to give it a gray background, padding, and a monospace font. The <h2> tag is used to give the block a title, and we've styled it to make it slightly larger and add some margin at the bottom. Inside the <section> tag, we've used the <pre> and <code> tags to contain our code, just like before.
