WordPress code blocks are a great way to display code snippets in your blog posts. They allow you to add code snippets to your posts and format them in a way that is easy to read and understand for your readers.

Here’s how to use code blocks in WordPress:

Use the Code Block: To add a code block to your post, you can use the code block button in the WordPress editor. This button is typically represented by < > and can be found in the toolbar at the top of the editor. Once you click the button, a code block will be added to your post where you can enter your code snippet.
Use a plugin: There are also a number of plugins that you can use to add code blocks to your WordPress posts. Some popular options include SyntaxHighlighter, Code Snippets, and WP-Syntax. These plugins typically provide a variety of features, such as automatic syntax highlighting and line numbering, which can make it easier to read and understand the code you are displaying.
Use the HTML editor: If you don’t want to use the built-in code block or a plugin, you can also add code snippets to your post by using the HTML editor. To do this, switch to the HTML editor in the WordPress editor and wrap your code snippet in <pre> and <code> tags. This will preserve the formatting of your code snippet and make it easier for your readers to read and understand.
Use the <pre> and <code> HTML tags: These tags are used to format code blocks in HTML. The <pre> tag is used to preserve the whitespace and line breaks of the code snippet, while the <code> tag is used to format the code itself. You can use these tags together to create a code block in your post. For example:

<pre>
  <code>
    // your code snippet here
  </code>
</pre>

Use the CSS to format the code block: You can also use CSS to format the code block to match your website’s design. This could include things like font size, background color, and line spacing. You can add the CSS to your theme’s stylesheet or use a plugin like Code Block Manager to add custom CSS to your code blocks.

By following these steps, you can add code snippets to your WordPress posts and format them in a way that is easy to read and understand for your readers. Using code blocks in your posts can help to improve the readability and understandability of your content and make it more engaging for your audience.

Use a Gist: Gist is a service provided by GitHub that allows you to share code snippets, files and even full project. You can create a Gist, copy the link and paste it into your WordPress post. This way, your code will be easily readable and editable for your readers.
Use a CodePen : CodePen is an online code editor and a social development environment that allows you to share your code snippets with others. You can create a Pen, copy the link and paste it into your WordPress post. This way, your code will be easily readable and editable for your readers, and also you can share a live demo of the code.
Use a GitHub : GitHub is a web-based platform that allows you to host and share your code snippets with others. You can create a repository, copy the link and paste it into your WordPress post. This way, your code will be easily readable and editable for your readers and also you can share the full project with others.
Use screenshots: If you don’t want to share the actual code, you can always take screenshots of your code and add them to your post. This can be useful if you’re showing off a specific feature or highlighting a particular section of your code.
Use comments and explanations: Finally, it’s important to provide context and explanations for your code snippets. Add comments to your code blocks, and provide explanations in the text of your post. This will help your readers understand the purpose of the code and how it works.

In addition to the steps outlined above, there are a few other things to keep in mind when displaying code in your WordPress blog posts:

Use consistent formatting: Use a consistent formatting style for your code blocks throughout your post. This includes things like indentation, line spacing, and font size. This will make your code easier to read and understand for your readers.
Use version control: If you’re sharing code snippets from a larger project, make sure to use version control. This will allow you to track changes to your code over time and ensure that the code you’re sharing is the most recent version.
Test your code: Before sharing your code, make sure to test it to ensure that it’s working properly. This will help to avoid confusion and errors for your readers.
Keep your code updated: If your code is part of a larger project, make sure to keep it updated with the latest changes. This will ensure that the code you’re sharing is the most recent version and will help to avoid confusion and errors for your readers.
Be aware of legal considerations: Be aware of any legal considerations when sharing code. This includes things like open-source licenses, copyright laws, and terms of service agreements. Make sure that you have the right to share the code you’re sharing and that you’re following any relevant laws or agreements.

By following these steps and keeping these considerations in mind, you can ensure that your code is easy to read and understand for your readers and that you’re following best practices for sharing code in your WordPress blog posts.
