[Plugin: AddToAny: Share/Bookmark/Email Button] Addtoany W3C CSS Validator Errors

Hey,

My Addtoany plugin are the latest version, today I checked my site thru W3C CSS Validator and found errors:

“URI : https://www.mywebsite.com/wp-content/plugins/add-to-any/addtoany.min.css?ver=1.3

1 .addtoany_list a img – Property opacity doesn’t exist in CSS level 2.1 but exists in : 0.7 0.7

1 .addtoany_list a:hover img, .addtoany_list a.addtoany_share_save img – Property opacity doesn’t exist in CSS level 2.1 but exists in : 1 1

Any ideas on how to fix it? Thanks
