Developers often hit print in a browser and watch their layouts disintegrate. Text gets cut, margins vanish, and images break. One developer spent weeks building a resume generator, rejecting canvas solutions for pure HTML. The core challenge was managing dynamic page breaks with CSS print media rules, a notoriously tricky area for web developers.

The breakthrough came from mastering specific CSS properties. Using `break-inside: avoid` on sections prevents content from being split across pages. Combined with `@page` rules to control margins and size, this creates a reliable print stylesheet. This approach avoids complex JavaScript libraries, favoring semantic markup for cleaner, more maintainable code.

After extensive tweaking with Puppeteer for headless rendering, the solution proved robust. To demonstrate it, a free tool called Resumemind was built. This showcases how these CSS rules behave in a production app, offering a practical reference for others struggling with PDF generation from web content.
