Flexbox is also a very great layout tool, but its one-directional flow has different use cases - and they actually work together quite well! Grid is the very first CSS module created specifically to solve the layout problems we’ve all been hacking our way around for as long as we’ve been making websites. First, we used tables, then floats, positioning and inline-block, but all of these methods were essentially hacks and left out a lot of important functionality (vertical centering, for instance). CSS has always been used to layout our web pages, but it’s never done a very good job of it. When implementations keep strings in a normalized form, they can be assured that equivalent This annex describes normalization forms for Unicode text.CSS Grid Layout (aka “Grid” or “CSS Grid”), is a two-dimensional grid-based layout system that, compared to any web layout system of the past, completely changes the way we design user interfaces. This document has been reviewed by Unicode members and other interested Regarding normalization of Unicode text, and information about conformance This annex also provides examples, additional specifications Strings have a unique binary representation.
