What is Code Injection in Ghost CMS?

Code injection in Ghost CMS is a feature that allows you to add custom CSS, JavaScript, and other code snippets to your site header and footer, and to individual posts and pages. This code will be injected into the HTML of your site, where it can be executed by the browser.

• Adding custom CSS to style your site.

• Adding Google Analytics tracking code to your site.
• Adding third-party integrations to your site.

Why Use Code Injection?

1. To add custom CSS and JavaScript to your site: This can be useful for styling your site in a unique way or adding custom functionality. For example, you could use code injection to add a custom navigation color, a contact form, or a social media sharing widget.
2. To integrate with third-party services: Many third-party services provide code snippets that you can add to your site using code injection. For example, you could use code injection to integrate with Google Analytics, Mailchimp, or Disqus.
3. To fix bugs or add new features to your theme. If you are using a custom theme for your Ghost CMS site, you can use code injection to fix bugs or add new features without having to modify the theme files directly.

The Ghost Code Injection feature allows you to add CSS, JavaScript, and other code snippets like Google Analytics to your site header and footer. This code will be injected into every page of your site.

Add CSS to the Site Header

One of the most common use cases for Code Injection is to add CSS to your Ghost site to customize the look and feel of your theme.

Let's say we had a site about animals and were using the Casper theme.

<style>
    header{background-color: #0080FF !important;}
</style>

Enter your code into the Site Header box and click on the Save button.

Here is the output of the code. The Navbar color changed successfully

To add JS code to the footer in Ghost CMS:

1. Go to Settings > Code Injection.
2. Paste your JS code into the Site Footer box.
3. Click Save.

For example, let's add a typewriter effect to our site Banner title. To quickly complete this work, we'll use the open-source TypewriterJS library. Here is an example of a simple JS code snippet that you could add to the site footer:

First, you should load the main script into the Site Footer.

<script src="<https://unpkg.com/typewriter-effect@latest/dist/core.js>"></script>

Then configure the TypewriterJS script and start it on the page. Whenever you add JS code in the Code Injection, you should wrap it in a <script> tag.

<script src="<https://unpkg.com/typewriter-effect@latest/dist/core.js>"></script>
<script>
    const app = document.querySelector('.site-title');

    const typewriter = new Typewriter(app, {
      loop: true,
      delay: 75,
    });

    typewriter
      .typeString('Beautiful Country is <strong>Bangladesh</strong>')
      .pauseFor(1000)
      .deleteChars(10)
      .typeString('<strong>USA</strong>')
      .pauseFor(750)
      .deleteChars(3)
      .typeString('<strong>UK</strong>')
      .pauseFor(500)
      .deleteChars(2)
      .typeString('<strong>India</strong>')
      .pauseFor(500)
      .deleteChars(5)
      .typeString('<strong>France</strong>')
      .pauseFor(1500)
      .deleteAll(50)
      .start();
</script>
