To customize the navigation bar with different font types and sizes, you'll need to modify the CSS file linked to your HTML file.

Here's a basic example of how you can do this:

```css .navbar { font-family: Arial, sans-serif; /* Change 'Arial' to your desired font */ font-size: 20px; /* Change '20px' to your desired size */ } ```

In this example, `.navbar` should be the class of your navigation bar. Replace it with the actual class name you're using.

To find the CSS file:

1. Open your HTML file and look for a line similar to this: ` `. The `href` attribute contains the path to your CSS file.

2. If your CSS file is in the same directory as your HTML file, it will be just the file name (e.g., "styles.css"). If it's in a subdirectory, it will include the directory name (e.g., "css/styles.css").

3. If you can't find a line like the one above, the CSS might be written directly in the HTML file, inside a `

It seems like you're working with a platform that doesn't allow direct access to HTML or CSS files. However, you can usually customize the navigation bar in the platform's settings or design interface.

If you want to change the font types and sizes, look for a section in the settings or design interface that allows you to change the font. This is usually under a section called "Typography", "Fonts", or "Text".

You can customize the navigation bar in your CSS file. Here's a basic example of how you can do it:

/* This is how you can set the font type */
.navbar {
  font-family: Arial, sans-serif;
}

/* This is how you can set the font size */
.navbar a {
  font-size: 18px;
}

Replace 'Arial, sans-serif' with the font type you want to use, and replace '18px' with the desired font size.

Remember to replace '.navbar' and '.navbar a' with the actual classes or IDs of your navigation bar and its links. If you want to apply the style to all links within the navbar, use '.navbar a'. If you want to apply the style to the entire navbar, use just '.navbar'.

Remember, if the font you want to use is not a common font, you will need to import it.

You can do this by using a `@import` statement at the top of your CSS file or by linking to an external CSS file in your HTML. For example:

@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap');

.navbar {
  font-family: 'Roboto', sans-serif;
}

This code imports the 'Roboto' font from Google Fonts and then applies it to the navigation bar.
