CNN currently uses Modernizr 3.3.1, and uses it to detect 3d CSS transforms. Due to some legacy code in Modernizr, this causes significant slowdowns when loading cnn.com. It's not clear to me whether CNN really needs to know about 3d transforms, and whether this check could simply be dropped. In any case, we've landed a fix [1] in Modernizr and released 3.6.0, which should no longer trigger slow behavior when detecting 3d transforms. Happy to provide more details for anyone interested. So to improve loading performance, CNN should either drop their check for 3d transforms, or upgrade to Modernizr 3.6.0. [1] https://github.com/Modernizr/Modernizr/pull/2291
Adam, can you reach out to CNN to upgrade to Modernizr 3.6.0? Thanks.
