Styling Preformatted Text with CSS

While the <pre> tag preserves whitespace and formatting, we can enhance its appearance using CSS. For instance, we can add borders, background colors, or padding to improve readability.

<style>
  pre.styled-pre {
    background-color: #f5f5f5;
    border-left: 3px solid #ccc;
    padding: 10px;
    overflow-x: auto;
  }
</style>

<pre class="styled-pre">
function helloWorld() {
  console.log("Hello, world!");
}
</pre>

Combining <pre> with Other Tags

The <pre> tag can be combined with other tags like <code>, <samp>, or <kbd> to semantically represent different types of text.

<pre><code>
SELECT * FROM users WHERE active = 1;
</code></pre>

Handling Long Lines within <pre>

By default, text inside a <pre> tag does not wrap, which can cause horizontal scrolling. To address this, we can use the CSS white-space property set to pre-wrap to allow long lines to wrap within the container.

<style>
  pre {
    white-space: pre-wrap;
    word-wrap: break-word;
  }
</style>
<pre>
This is a very long line of text that will wrap within the pre tag container to prevent horizontal scrolling.
</pre>

Accessibility Considerations

When using the <pre> tag, it's important to consider accessibility. For example, when displaying ASCII art or diagrams, we should provide descriptive text alternatives for screen readers.

<pre role="img" aria-label="A simple smiley face made with ASCII art">
:-)
</pre>

Deprecation of the width Attribute

Previously, the <pre> tag supported a width attribute to specify the number of characters per line. This attribute is now deprecated and should be replaced with CSS for controlling layout and presentation.

<style>
  pre {
    width: 80ch; /* 80 characters wide */
  }
</style>

Use Cases for the <pre> Tag

• Displaying Code Snippets: Preserving indentation and formatting for programming tutorials or documentation.
• Showing Log Files: Presenting log entries where exact formatting is crucial for readability.
• ASCII Art: Creating text-based art where spaces and line breaks define the visual structure.

By incorporating these enhancements and additional examples, we can provide a more comprehensive understanding of the <pre> tag and its practical applications in web development.
