CSS Grid is a two-dimensional grid system used to work on the layout of UI elements and segments of a webpage. The Grid comprises horizontal and vertical lines to form rows and columns, much like a table.
Bootstrap has a responsive grid system, with custom breakpoints. It offers a mobile-first design that makes a single code scale for multiple devices like phones, tablets, and desktops. Much like the CSS Grid, this too is defined using a two-dimensional grid made up of horizontal and vertical lines forming rows and columns.
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.
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).
To nest your content with the default grid, add a new .row and set of .span* columns within an existing .span* column. Nested rows should include a set of columns that add up to the number of columns of its parent.
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.
Bootstrap helps us to create columns using the "col" class for a single column in a row. We can use the "col" class twelve times to create twelve columns in one row. Bootstrap classes use for a responsive grid system.
