Grid

Grid Options
Bootstrap grid allows building an equal height flexbile blocks easily

While Bootstrap uses em or rem for defining most sizes, px are used for grid breakpoints and container widths. This is because the viewport width is in pixels and does not change with the font size.

Grid Column

Using a single set of .col-md-* grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns within any .row.

Row columns

Use the responsive.row-cols-*classes to quickly set the number of columns that best render your content and layout. Whereas normal .col-*classes apply to the individual columns (e.g., .col-md-4), the row columns classes are set on the parent .rowas a default for contained columns. With.row-cols-autoyou can give the columns their natural width.

Order

Use .order- classes for controlling the visual order of your content. These classes are responsive, so you can set the order by breakpoint (e.g., .order-1.order-md-2). Includes support for 1 through 12 across all five grid tiers.

Move columns to the right using .offset-md-* classes. These classes increase the left margin of a column by * columns. For example, .offset-md-4 moves .col-md-4 over four columns.
