Many web sites fall in the middle of these metrics. For these sites, the best solution generally is to deploy the JavaScript and CSS as external files. The only exception where inlining is preferable is with home pages, such as Yahoo!'s front page and My Yahoo!.
Home pages that have few (perhaps only one) page view per session may find that inlining JavaScript and CSS results in faster end-user response times.
For front pages that are typically the first of many page views, there are techniques that leverage the reduction of HTTP requests that inlining provides, as well as the caching benefits achieved through using external files. One such technique is to inline JavaScript and CSS in the front page, but dynamically download the external files after the page has finished loading. Subsequent pages would reference the external files that should already be in the browser's cache.
Luciano Ferrer on 06 Jun 13"More and more we see people using horizontal sliding panels on their websites. And they usually look very nice! Some will put a contact or login form in there, others will put some information about them and their website, or even things like a tag cloud or social networking buttons. Horizontal sliding panels are great for many situations, but like everything else, they're not always ideal. It depends on the project. To see what I mean by 'horizontal sliding panel', go have a look at my other site Design-Newz, and click on the 'want more' button that's on the right above the navigation bar."
