Summernote is a popular WYSIWYG editor for web applications, and it supports a dark mode theme out of the box. Here are the steps to put Summernote in dark mode:

1. Download the Summernote CSS file from the official website or use the following link: https://cdnjs.cloudflare.com/ajax/libs/summernote/0.8.18/summernote-bs4-dark.css
2. Include the CSS file in your HTML code. You can do this by adding the following line to the head section of your HTML document:

<link href="https://cdnjs.cloudflare.com/ajax/libs/summernote/0.8.18/summernote-bs4-dark.css" rel="stylesheet">

3. Initialize Summernote with the "bs4-dark" theme by adding the "theme" option to the initialization code. Here's an example:

$(document).ready(function() {
  $('#summernote').summernote({
    height: 300,
    theme: 'bs4-dark'
  });
});

4. Save your HTML file and reload the page. Summernote should now be displayed in dark mode.

Note that Summernote also provides other themes, such as "default" and "bs4", which you can use by changing the "theme" option in the initialization code.

More Information on Summernote on Dark Mode

1. Customizing the dark mode theme: If you want to customize the dark mode theme of Summernote, you can download the source code of the CSS file from the official website and modify it according to your needs. You can change the colors, font sizes, and other styles to create a theme that suits your website's design.
2. Supporting dark mode in different browsers: Summernote's dark mode theme works in most modern browsers, including Chrome, Firefox, Safari, and Edge. However, some older browsers may not support the CSS features used in the theme, which could result in unexpected visual results.
3. Using Summernote in a responsive design: If your website is designed to be responsive, you may need to adjust the height of the Summernote editor to ensure it fits well on different screen sizes. You can do this by setting the "height" option in the initialization code to a percentage value, such as "100%", which will make the editor take up the full height of its container.
4. Debugging issues with dark mode: If you encounter any issues with Summernote's dark mode, such as text or icons being hard to read, you can use your browser's developer tools to inspect the CSS styles being applied to the editor. This can help you identify any conflicts or issues with your website's CSS that may be affecting the dark mode theme.
