Title: Invalid HTML Last modified: August 30, 2016 --- # Invalid HTML * [Michael](https://wordpress.org/support/users/nikonratm/) * (@nikonratm) * [10 years, 7 months ago](https://wordpress.org/support/topic/invalid-html-6/) * Current CSS tags are invalid when not in the document because they don’t contain the attribute _property_ (i.e. [http://stackoverflow.com/questions/18549726/element-link-is-missing-required-attribute-property](http://stackoverflow.com/questions/18549726/element-link-is-missing-required-attribute-property)). Ultimately this causes invalid HTML per W3C validator. * Fix is to edit line 2733 of _class-bwp-minify.php_ to: `. esc_attr($media) ."' property='stylesheet' />\r\n";` and 2741 to: `. esc_attr($media) . "' property ='stylesheet' />\r\n";` * [https://wordpress.org/plugins/bwp-minify/](https://wordpress.org/plugins/bwp-minify/) Viewing 1 replies (of 1 total) * Plugin Author [Khang Minh](https://wordpress.org/support/users/oddoneout/) * (@oddoneout) * [10 years, 7 months ago](https://wordpress.org/support/topic/invalid-html-6/#post-6649506) * Thanks for the heads-up, will add that property in the next version.
