Adding line numbers to your code snippets can be a handy way to enhance readability and make it easier for others to reference specific lines of code. In this article, we will guide you through the simple process of adding line numbers to all lines in Google Prettify.
Google Prettify is a powerful tool that allows you to display code snippets in a visually appealing and syntax-highlighted format. By default, Google Prettify does not display line numbers. However, with a few quick adjustments, you can easily configure it to show line numbers alongside your code.
To begin, locate the HTML code block where you have embedded your code snippet using Google Prettify. Add the following class to the
tag:class="prettyprint linenums"
This class instructs Google Prettify to display line numbers for each line of code within the
tag. Once you have added the "linenums" class, save your changes and refresh the page to see the line numbers in action.If you want to customize the appearance of the line numbers further, you can modify the CSS styles associated with the "linenums" class. For example, you can adjust the font size, color, or alignment of the line numbers to better suit your website's design.
In addition to displaying line numbers for all lines in your code snippet, Google Prettify also offers the flexibility to highlight specific lines of code. To mark a line with a specific color, add the "data-line" attribute to the
tag:data-line="3"
In this example, the line with the number "3" will be highlighted in a different color, making it stand out from the rest of the code. You can specify multiple line numbers by separating them with a comma (e.g., data-line="1, 5, 9").
By incorporating line numbers and customized line highlighting into your code snippets with Google Prettify, you can improve the readability and visual appeal of your technical documentation, tutorials, and blog posts. These simple enhancements can make it easier for your readers to follow along with your code examples and better understand the logic behind your programming solutions.
In conclusion, adding line numbers to all lines in Google Prettify is a straightforward process that can significantly enhance the presentation of your code snippets. Remember to use the "linenums" class to display line numbers and experiment with customizing the appearance and highlighting of specific lines to create visually engaging and informative code displays.
