Displaying code snippets on your WordPress website presents unique challenges that go beyond simply pasting text into your editor. When you attempt to add programming code directly into WordPress, the platform often interprets it as executable content rather than displaying it as readable text. This common frustration affects developers, technical bloggers, educators, and anyone creating programming tutorials or documentation. Understanding the proper methods to showcase code while maintaining formatting, readability, and visual appeal is essential for creating professional technical content that serves your audience effectively.
The WordPress content management system processes HTML by default, which means pasting raw code directly into posts or pages can lead to broken layouts, missing content, or unexpected functionality. Additionally, plain text code lacks the visual clarity that helps readers distinguish between different programming elements, making it difficult for visitors to understand and copy code accurately. This comprehensive guide explores three proven methods to display code in WordPress, from native WordPress blocks to advanced plugins and manual HTML techniques, ensuring your code snippets look professional and function correctly.
Understanding the Challenge of Displaying Code in WordPress
WordPress operates as an HTML-based content management system, automatically processing any code you paste into the editor. When you insert HTML, JavaScript, PHP, or other programming languages directly into your content, WordPress attempts to execute or render that code rather than displaying it as text. This behavior creates several problems for content creators who need to share code snippets with their audience.
The core issue stems from WordPress treating angle brackets, quotes, and special characters as functional elements rather than displayable content. For example, if you paste an HTML snippet containing div tags, WordPress will either attempt to create those div elements in your page structure or strip them out entirely during the sanitization process. Similarly, PHP code might trigger errors if WordPress interprets it as executable code, while JavaScript could run unexpectedly and interfere with your site’s functionality.
Beyond the technical execution problems, unformatted code lacks visual distinction from regular text. Professional code presentation includes syntax highlighting, where different code elements appear in different colors, line numbering for easy reference, and proper indentation that reflects the code’s logical structure. Without these features, even correctly displayed code becomes difficult to read, understand, and implement, especially for readers who may be learning programming concepts.
Method 1: Using the WordPress Native Code Block
WordPress introduced the Gutenberg block editor in version 5.0, which includes a dedicated Code block specifically designed for displaying programming snippets. This native solution provides a straightforward way to showcase code without installing additional plugins, making it ideal for occasional code sharing or users who prefer minimal plugin dependencies.
Accessing and Using the Code Block
To add a Code block to your WordPress post or page, open the content editor and click the plus icon to add a new block. You can either browse through the block categories to find the Code block under Formatting, or simply type forward slash followed by “code” to quickly insert the block using the keyboard shortcut method. Once the Code block appears in your editor, you can immediately begin pasting or typing your code snippet into the designated area.
The WordPress Code block automatically handles basic formatting to prevent code execution. It wraps your content in appropriate HTML tags that tell browsers to display the code as preformatted text rather than interpreting it as functional code. This means you can safely paste HTML, CSS, JavaScript, PHP, or any other programming language without worrying about WordPress executing the code or corrupting your page layout.
Limitations of the Native Code Block
While the WordPress Code block solves the fundamental problem of displaying code safely, it comes with several limitations that may not suit professional developers or technical content creators. The block provides minimal styling options, typically displaying code in a monospace font with a simple background color determined by your active theme. There is no built-in syntax highlighting, meaning all code appears in a single color without visual differentiation between variables, functions, strings, or comments.
The lack of line numbers makes it difficult for readers to reference specific lines when discussing code or following along with tutorials. Additionally, the Code block does not offer features like code copying buttons, language specification for proper highlighting, or the ability to highlight specific lines to draw attention to important sections. For websites that regularly publish technical content, these limitations often necessitate more robust solutions.
Method 2: Using SyntaxHighlighter Evolved Plugin for Professional Code Display
The SyntaxHighlighter Evolved plugin represents the most popular solution for displaying code in WordPress, offering comprehensive features that transform basic code blocks into professional, visually appealing presentations.

Best Practices for Displaying Code in WordPress
Implementing effective code display goes beyond simply installing a plugin or using the native Code block. Following established best practices ensures your code snippets provide maximum value to readers while maintaining professional presentation standards that enhance your site’s credibility and usefulness.
Choosing the Right Display Method
Consider your content strategy when selecting a code display method. If you occasionally share code snippets and prioritize simplicity, the native WordPress Code block provides sufficient functionality without additional plugin overhead. For technical blogs, tutorial sites, or documentation platforms that regularly publish code-heavy content, investing in a dedicated syntax highlighting plugin delivers significantly better user experience through enhanced readability and professional presentation.
Evaluate your technical requirements including the programming languages you primarily feature, whether you need advanced features like line highlighting or code folding, and how important visual customization is for your brand identity. These factors should guide your plugin selection, ensuring you choose a solution that meets your current needs while providing room for future growth as your content library expands.
Optimizing Code Snippet Presentation
Always specify the programming language for your code snippets when using plugins that support language detection. This ensures proper syntax highlighting that accurately represents the code structure, making it easier for readers to understand different code elements. Include brief explanations before or after code blocks describing what the code does, why specific approaches were chosen, or what readers should pay attention to when reviewing the snippet.
Keep code snippets focused and concise, showing only the relevant portions necessary to illustrate your point. For lengthy code examples, consider breaking them into smaller, logical sections with explanations between segments. This approach prevents overwhelming readers with large blocks of code while helping them understand the progression and purpose of each section. When presenting modified or updated code, highlight the changed lines to draw attention to the specific modifications being discussed.
Ensuring Mobile Responsiveness and Accessibility
Test your code displays on various devices to ensure proper rendering on mobile phones and tablets. Code snippets should remain readable without excessive horizontal scrolling, with text large enough to read comfortably on smaller screens. Many syntax highlighting plugins include responsive design features, but verifying actual mobile appearance prevents user experience issues that could drive visitors away from your content.
Consider accessibility requirements for visitors using screen readers or requiring high contrast displays. Ensure your chosen color theme provides sufficient contrast between code elements and background colors, making text readable for users with visual impairments. Include descriptive text around code blocks that explains the code’s purpose and functionality, helping all users understand the content regardless of how they access your site.
Pro Tips for Advanced Code Display Management
Experienced developers and technical content creators can implement several advanced techniques to further enhance code presentation and user experience on WordPress sites. These pro tips help you maximize the effectiveness of your code displays while addressing common challenges that arise in professional technical publishing.
Creating Consistent Code Styling Across Your Site
Establish a standardized approach to code presentation by selecting a single syntax highlighting theme and consistently applying it across all posts and pages. This consistency helps readers develop familiarity with your code’s visual presentation, making it easier to quickly scan and understand code snippets as they navigate through multiple articles. Document your chosen theme and any custom styling rules in your content guidelines to ensure consistency when multiple authors contribute to your site.
Consider creating reusable code templates for common programming patterns or frequently referenced snippets. Many syntax highlighting plugins support saved snippets or shortcode libraries that let you quickly insert standardized code examples without retyping or reformatting. This approach not only saves time but also ensures accuracy and consistency across your content library.
Implementing Code Download and Copy Features
Enable easy code copying for your readers by ensuring your chosen plugin includes copy-to-clipboard functionality. This feature dramatically improves user experience by eliminating the need for manual selection and copying, which can be error-prone especially with formatted code that includes special characters or whitespace. Some plugins also support downloading code snippets as individual files, particularly useful for longer examples that readers might want to save for reference or testing.
For tutorial content that builds progressively, consider offering complete working examples as downloadable files hosted on your server or linked from code repositories like GitHub. This gives readers access to fully functional code they can run and experiment with, complementing the snippet-based explanations in your articles. Include clear attribution and licensing information for any downloadable code to clarify usage rights and requirements.
Optimizing Performance for Code-Heavy Content
Sites publishing extensive code examples should implement performance optimization strategies to prevent syntax highlighting from impacting page load times. Configure your plugin to load highlighting libraries only on pages that actually contain code blocks, reducing unnecessary script loading on other content. Enable lazy loading for code blocks that appear below the fold, deferring their processing until users scroll to them.
Monitor your site’s performance metrics using tools like Google PageSpeed Insights or GTmetrix, paying particular attention to how code highlighting affects loading times. If performance issues arise, consider switching to lighter syntax highlighting solutions or implementing caching strategies that pre-render highlighted code on the server rather than processing it client-side in visitors’ browsers.
