Here is an updated README.md:

Date Localization

This code localizes dates in HTML elements for use in Webflow. It can also be used in any web project.

It targets elements with the wunder-loc-element="date" attribute. This is the only required attribute.

It loops through all elements with this attribute and localizes the date based on the following optional attributes:

• wunder-loc-language - The language to localize to (e.g. "en-US")
• wunder-loc-format - Either long, short, or custom

If wunder-loc-format is custom

• wunder-loc-year - Custom year formatting (e.g. "numeric")
• wunder-loc-month - Custom month formatting
• wunder-loc-day - Custom day formatting
• wunder-loc-weekday - Custom weekday formatting

It uses Date.toLocaleDateString() to localize the dates based on the provided options.

If no options are provided, it will use the default locale.

So in summary:

• Add wunder-loc-element="date" to any element containing a date
• Optionally add language and/or format options
• The code will handle localizing the date on that element
