Embed a trail karma donate button.
Step 1: Choose a Region
Step 2: Configuration
Step 3: Get the code
You can optionally provide your own custom CSS file to custom style the widget to your desire.
You can set the widget width to 100% to have the widget height responsively adjust (must use the JS code, not iframe).
The direct URL to the widget source is: https://www.trailforks.com/widgets/karma_donate/
the following are the URL GET paramaters you can pass: id, width, x, t. Use the data-* in the "get the code" box above for reference.
