Accessibility improvements

Hi,

First, thank you for this plugin! ??

I’d like to ask whether you could improve the front-end accessibility of the plugin if possible.

For example, please do not use <i> tag for icons. It’s better to use <span> instead as that tag does not throw any warning in any accessibility evaluation tool either and changing the tag has no effect on the actual icon display.

Thank you for consideration.

Best regards,

Oliver
