ISSUU embeds not right on tablet and phone

Hi,

I embed books from ISSUU in some pages. They didn’t show right om tablets and phones. I corrected it in the custom css in customizer by adding this line:

.issuuembed.issuu-isrendered {
width: 100%!important;
}

This solved it for me but mayby it is of help for you to put it into the theme.

Best regards,

Alfred.
