Accessible simplemodal

[arturi]

Hi! Great plugin, thank you for your work!

Upon encountering simplemodal on splashthat.com I tried using it with keyboard (tab) and found it difficult. I’ve also noticed there are no labels, aria- and role attributes that help screen readers better process the content.

I’m suggesting to look at what https://github.com/ghosh/micromodal is doing and incorporate their best ideas here too: trapping focus inside the modal dialog, adding labels and proper attributes.
