Windows versions of Outlook 2016 through 2021 use Microsoft Word's rendering engine rather than a browser engine, causing modern layout methods such as Flexbox and CSS Grid to fail, forcing developers to fall back to nested table markup.
Flexbox entered mainstream browsers in 2012.
The combination of display: flex; align-items: center; justify-content: center can achieve intuitive element centering.
Servo initially used a self-developed Flow layout engine, and in recent years has shifted toward reimplementing a modern layout system based on CSS specifications, including support for Flexbox and CSS Grid.
Modern CSS has capabilities such as Grid, Flexbox, custom properties (CSS Variables), and container queries, enabling complex layouts in pure CSS that previously required scripts or structural hacks.
In Flex layout, once display:flex is declared on the parent container, justify-content controls main-axis alignment and align-items controls cross-axis alignment, enabling horizontal and vertical centering of content.
