You can add the following code into Dashboard – Theme Options – Advanced – Custom JS to preload this resource <link rel=”preload” href=”https://example.com/wp-content/themes/dt-the7/fonts/icomoon-the7-microwidgets-16×16/fonts/icomoon-the7-microwidgets-16×16.ttf?dqeoeo” as=”font” type=”font/ttf” crossorigin=”anonymous”> Do not forget to replace example.com to your actual site url. But i actually do not recommend to do this, we do not add preloading for these fonts because it will actually decrease the page loading speed. This is described by the simple fact that when you increase priority to download these icon sets, the other most important resources (css styles and required scripts required to display the page as soon as possible) will be delayed.
