### Table-like
|
||||
|
||||
This creates columns that have different widths, but size accordingly according
|
||||
to the circumstances.
|
||||
|

.container {
|
||||
display: flex;
|
||||
}

||||
/* the 'px' values here are just suggested percentages */
|
||||
.container > .checkbox { flex: 1 0 20px; }

||||
.container > .subject { flex: 1 0 400px; }
|
||||
.container > .date { flex: 1 0 120px; }
|
||||
|
||||
### Vertical
|
||||
|
||||
Vertically-center all items.
|
||||
|
||||
.container {
|
||||
align-items: center;
|
||||
}
