16. Location Tracker Maciej Mensfeld Bootstrap basics: grids The default Bootstrap grid system utilizes 12 columns, making for a 940px wide container without responsive features enabled. With the responsive CSS file added, the grid adapts to be 724px and 1170px wide depending on your viewport. Below 767px viewports, the columns become fluid and stack vertically.

17. Location Tracker Maciej Mensfeld Bootstrap basics: grids For a simple two column layout, create a.row and add the appropriate number of.span* columns. As this is a 12-column grid, each.span* spans a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent). Make any row "fluid" by changing.row to.row-fluid. The column classes stay the exact same, making it easy to flip between fixed and fluid grids. The fluid grid system uses percents instead of pixels for column widths. It has the same responsive capabilities as our fixed grid system, ensuring proper proportions for key screen resolutions and devices.

18. Location Tracker Maciej Mensfeld Bootstrap basics: grids Move columns to the right using.offset* classes. Each class increases the left margin of a column by a whole column. For example,.offset4 moves.span4 over four columns.

19. Location Tracker Maciej Mensfeld Responsive bootstrap For faster mobile-friendly development, use these utility classes for showing and hiding content by device. Below is a table of the available classes and their effect on a given media query layout (labeled by device).
