Basic grid layouts to get you familiar with building within the Bootstrap grid system.
-Get three equal-width columns starting at desktops and scaling to large desktops. On mobile devices, tablets and below, the columns will automatically stack.
-Get three columns starting at desktops and scaling to large desktops of various widths. Remember, grid columns should add up to twelve for a single horizontal block. More than that, and columns start stacking no matter the viewport.
-Get two columns starting at desktops and scaling to large desktops.
-No grid classes are necessary for full-width elements.
- -Per the documentation, nesting is easy—just put a row of columns within an existing row. This gives you two columns starting at desktops and scaling to large desktops, with another two (equal widths) within the larger column.
-At mobile device sizes, tablets and down, these columns and their nested columns will stack.
-The Bootstrap 3 grid system has four tiers of classes: xs (phones), sm (tablets), md (desktops), and lg (larger desktops). You can use nearly any combination of these classes to create more dynamic and flexible layouts.
-Each tier of classes scales up, meaning if you plan on setting the same widths for xs and sm, you only need to specify xs.
-Clear floats at specific breakpoints to prevent awkward wrapping with uneven content.
-Reset offsets, pushes, and pulls at specific breakpoints.
