Due to this website being a static site, JavaScript is used to create dynamic and interactive components of this site. Here is a list of how JavaScript is used on this site:
* The header of every page uses JavaScript to detect the visitor's current date, so the header will display a top blurb and in some cases also changes the header background on certain dates, including:
* When this site is viewed on mobile devices, the navigation bar's hamburger menu uses JavaScript to enable using the Escape key to close the navigation manu.
* Zach Leatherman's [details-utils](https://www.npmjs.com/package/@zachleat/details-utils) JavaScript package is used to automatically expand sidebar table of contents on wide screens.
* Every page has a button on the bottom right corner to allow you to quickly scroll to the top of the page. This scroll-to-top button uses JavaScript to show or hide the button based on your scroll position.
* A "Back to top" link that does not use JavaScript is available on each page's bottom footer if JavaScript is disabled, but the JavaScript version allows visitors to quickly scroll to the top of the page without needing to reach the bottom footer.
* [Website Carbon Badge](https://www.websitecarbon.com/badge/), which is placed on the home page, uses JavaScript to calculate the carbon footprint of this website.
* [Guestbook](/guestbook) uses JavaScript to send form data to my private Discord channel via Discord webhook, and fetch data from Google Sheets to display messages on the web page (guestbook code by [Vera Konigin](https://groundedwren.neocities.org/pages/demo_controls/guestbookDemo)).
You can still access most of the content of this site with JavaScript disabled, but the above components will not work as intended.
