Hello,

I’m french,

I have a custom image for the scroll top button. The plugin displayed this line : “<style>a.scrollup-image {background-image: url(“‘.$scrollup_custom_image.'”) !important; }</style>”. which isn’t valid w3c.

So i change by :

global $wp_styles;
$wp_styles->add_inline_style(‘styleSmoothScrool’, ‘ a.scrollup-image {background-image: url(“‘.$scrollup_custom_image.'”) !important; }’);
$wp_styles->enqueue(array(‘styleSmoothScrool’));

If you can add it for your future update, for the w3c validation ?

Thanks.
