Tailwind CSS
/Advanced
Bundle Size Optimization
Definition
The architectural reality that Tailwind naturally scales to a flat curve in production; no matter how large the application gets, the CSS file stops growing.
Explain Like I'm New
In traditional CSS, every new feature adds 100 new lines of CSS. A 50-page app might have a 500kb CSS file. In Tailwind, once you've used `flex`, `p-4`, and `text-center` once, they are in the bundle. Building 50 more pages uses those same exact classes. The CSS file literally stops growing around 15kb.
Real World Example
Netflix completely rewriting their UI. They found that traditional CSS grew infinitely. Moving to utility-first CSS resulted in an extremely small, strictly capped CSS payload.
