During scheduled maintenance or updates, it's important to provide visitors with a clear indication that the website is temporarily unavailable. This HTML page serves that purpose by displaying a friendly message informing users about the maintenance process and assuring them that the website will be back online shortly.

The code you provided is for a website undergoing maintenance. Here's a breakdown of how it works:

• The HTML defines the basic structure of the page.
• It includes sections for a title, message, progress bar, countdown timer, contact button, maintenance ID, and last checked time.

• The CSS styles the appearance of the page elements.
• It controls the layout, fonts, colors, and background.

The JavaScript code adds interactivity to the page. Here are the key functionalities:

1. Checks website state: It periodically checks if the website is still under maintenance by fetching the current page content.

2. Displays countdown timer: It sets an initial countdown time (default 5 minutes) and updates it on the page every second.

3. Redirects to updated website:

   • If the countdown reaches zero or the website content doesn't indicate maintenance anymore, it triggers a redirect to the updated website after a short delay (default 3 seconds).

4. Displays hostname and contact email: It retrieves the current website hostname and dynamically updates the contact button link (mailto:admin@<hostname>) and displayed hostname.

5. Generates and stores maintenance ID: It generates a unique identifier (UUID) for this maintenance session and stores it in the browser's local storage for reference.

6. Displays last checked time: It updates the "Last checked" time with the current time whenever it checks the website state.

In summary, this webpage informs visitors that the website is under maintenance and provides an estimated time until it's back online. It also offers a contact option and displays technical details for debugging purposes.

1. Make sure you have Docker installed on your machine. If not, you can download and install it from Docker's official website.
