Lighthouse Test Results – Improvements needed?

Hi there, I was happy to see my website performance to be dramatically improved after I installed and activated WP Fastest Cache plugin. My website runs good now - both PC and mobile versions (webpagetest.org). But I have a couple of questions regarding Lighthouse test report, which is also provided by the same website. A couple of "red" items got my attention. Issue 1 - <html> element does not have a [lang] attribute; Issue 2 - Includes front-end JavaScript libraries with known security vulnerabilities (jQuery@1.12.4) And there is another suggestion that could improve home page performance - to have a different, smaller Featured slides images for Mobile layout. I used to have this option with a different website content platform, it did make a difference in webpage performance. Alternatively you could change the settings in your Theme - to make the first slider visible after it has been uploaded. By default Slideshow will start as soon as two slider are available (in Image Loader). You do not need to wait for the second image to show the first slider, there is always a sufficient transition delay. I hope you do not mind receiving a feedback my feedback from your customers. Thank you for your great job! Olga
