Join Morten Rand-Hendriksen for an in-depth discussion in this video Modularize CSS for HTTP/2, part of HTTP/2: Developing for Performance.
- [Narrator] Now that we're working with HTTP/2,…we need to rethink how we're handling stylesheets.…In the old way of doing things,…when we generated stylesheets,…we would take all the modules…for the stylesheet that we used,…Sass, or PreCSS, or something else to generate,…and then put them all into one single file…so that we avoided blocking the load of the page.…But the consequence of that is…we would load in one gigantic CSS file…that would have all the styles…for all the possible modules and pages…we might load up, all of it contained in one place,…and that means if we made one change…to any of these modules,…we'd have to reload the entire stylesheet…and invalidate all caches,…and more importantly, we would load a ton of styles…that were actually not used on the current page in question.…
Well, HTTP/2 solves that problem,…because we can now modularize our CSS…and split it up into separate files,…and only load in the files…we actually need for the page in question,…and then those files can be cached on the server…
