    Hello,

    Using this plugin is really great but since I am using it I get this error in W3 Validator.

    Bad value only screen and (-webkit-min-device-pixel-ratio: 2) for attribute media on element link: Expected a letter at start of a media feature part but saw – instead.

    My website is host-reviews.nl and I realy like to know how I can get rid of this validation error:)

    Somebody hase any suggestions?

    Regards

    Morgend Joepioooo;
    You have the same error without Autoptimize; cfr. this validation report.

    The problem is with the value of the media-attribute on this line;
    <link rel='stylesheet' id='retina-css' href='https://www.host-reviews.nl/wp-content/themes/inovado/framework/css/retina.css' type='text/css' media='only screen and (-webkit-min-device-pixel-ratio: 2)' />

    The validator does not expect media-queries with vendor prefixes there (the dash in “-webkit”).

    Hope this helps,
    frank

    Aha I see…

    I found the rule but is there an easy way to change it so W3 will validate?

    I found more people with this problem but not an easy fix. Is there a fix or should I leave it as is?

    Thanks for your answer:)

    hmmm … you could make it just media=”screen” and move the (-webkit-)min-device-pixel-ratio in the retina.css file? that way the HTML-validator won’t see it (but you’ll force all browsers to download the file, which implies a performance impact)?

    Yeah your right. I will just leave it this way. It is the only error I got so…

    Thanks for the help:)
