Hey guyz.. After exploring how browsers construct and render webpages, I wanted to understand another important part of frontend engineering. How does a browser decide where every element belongs on a webpage? Think about an online shopping application. It might have a navigation bar, product cards, search filters, images, buttons and several content sections.

On a desktop, these elements might appear side by side. On a mobile device, they may be stacked vertically. The content hasn’t necessarily changed, but the layout has.

How does that happen?

That’s where CSS layout systems come into play.
