# Sections and cards
A [DashboardContent](/dashboards/reference.md#dashboardcontent) is composed of sections and cards.
* Each section has a title and cards disposed on a grid.
* Each card is a white block organizing [charts](/dashboards/charts.md) horizontally or vertically.
Dashboard structure
The size and position of each card is defined by a 12 column grid, with as many rows as needed. Cards size and position are set with `{h,w,x,y}` properties :
* `h` is the number of rows that the card takes.
* `w` is the number of columns that the card takes
* `{x,y}` are the coordinates of the top left corner of the card on the grid
Here is a sample grid with five cards and their corresponding properties :
