Platform/Layout

The Platform Layout Team is primarily responsible for Gecko's style system and layout engine. We strive to build and maintain an engine that is both high-performance and standards-compliant, while providing support for features unique to Firefox.

The team's technical domains within Gecko include:

• CSS animations and transitions
• CSS parsing and computation
• Layout (of all types, including block and inline, positioned, columns, floats, flexbox, grid, form controls, images, video, tables, and text)
• Printing
• SVG
