Dirty hacksBrowser isolation
Hacks thatnever leave
Our needs oftengrow beyond our tools
Layout is always hacked
60+ lines of code to definecolumn behaviourFlexbox grid example
35+ lines of code anytimeyou touch a media queryFlexbox grid example
Now we have declarative grids
Total of 2 fr unitsEach is worth 1 / 2 fr units
Create white space
Across rows and columns
grid-column: span 2;
We can break out of the grid
Building up complex grids
Flexible complex grids
Simpler withVariables
Define how columns and spans collapse across viewports
Variables create relationships between values
Experimentation with values

Autonomous layout
Flexbox
Flex wrap: Two fixed widths320px 480px = 800px+
Less than 800px space available

Font-size: 50ctw(not real CSS, I wish)
ResizeObserver
We can use CSS Variables to communicate
Getting variables via JS
Setting variables via JS
Container basedfluid typography
In the browser
The problem withreporting element size directly
CSS can’t range match a selector
Communicate shape
An preview might exist with different shapeshttp://lincolnloop.github.io/element-queries-example/
