# CSS Grid Cheatsheet

[**CSS Grid Layout**](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout) introduces a two-dimensional grid system to CSS: grids can be used to lay out major page areas or small user interface elements.

## Syntax

### Main properties

```css
.container {
  display: grid | inline-grid; /* Also subgrid is avaiable */
  grid-template-rows: -line_name- -row_size- .. | repeat(-integer-, -rows_size- -lines_name-);
  grid-template-columns: -line_name- -column_size- .. | repeat(-integer-, -columns_size- -lines_name-);
  grid-template: <grid-template-rows> / <grid-template-columns>;
}

.item {
  grid-area: <grid-row-start> / <grid-column-start> / <grid-row-end> / <grid-column-end>;
}  
```

### Other properties

```css
.container {
  grid-template-areas: "-area_name- | . | none"
                       "..";
                       
  grid-row-gap: -lines_size-;
  grid-column-gap: -lines_size-;
  grid-gap: <grid-column-gap> <grid-row-gap>;
  
  justify-items: start | end | center | stretch;
  align-items: start | end | center | stretch;
  justify-content: start | end | center | stretch | space-around | space-between;
  align-content: start | end | center | stretch | space-around | space-between;
  
  grid-auto-rows: -rows_size-;
  grid-auto-columns: -columns_size-;
  grid-auto-flow: row | column | row dense | column dense; /* default is row */
  
  grid: none | <grid-template-rows> / <grid-template-columns> | <grid-auto-flow> [<grid-auto-rows> [/ <grid-auto-columns>]];
}

.item {
  grid-row-start: -integer- | span -integer- | -name- | span -name- | auto;
  grid-row-end: -integer- | span -integer- | -name- | span -name- | auto;
  grid-column-start: -integer- | span -integer- | -name- | span -name- | auto;
  grid-column-end: -integer- | span -integer- | -name- | span -name- | auto;
  grid-row: <grid-row-start> / <grid-row-end>;
  grid-column: <grid-column-start> / <grid-column-end>;
  
  order: <integer>; /* default is 0 */
  
  justify-self: start | end | center | stretch;
  align-self: start | end | center | stretch;
}
```
