Checkout your resources included in head section. HTML/Resource
rendering starts from top to bottom, so if head section has many
resources, will cause delay to load body. Once you have only needed
resources in head (css files, meta tags) and other resource requests
moved towards end of HTML, then solution provided by @shaileshbassi
should work.You should also consider using preload/prefetch meta tags
