This Sequence Container is made of two images.

1. Get the alt text for each image.  For this problem the alt text was already added to the image page.
2. Make sure the images are set to Presentation Only on the image page for the images in the sequence container.

1. Add the alt text to each step as screenreader only text.

1. Removed all nested checkboxes. In Safari, check that the screen reader moves smoothly from one checkbox to the next and that the screen reader reads the items in the correct order.
