| Use col-{breakpoint}-auto classes to size columns based on the natural width of their content. | Variable width content |
| When using Bootstrap’s source Sass files, you have the option of using Sass variables and mixins to create custom, semantic, and responsive page layouts. | Sass mixins |
| Our predefined grid classes use these same variables and mixins to provide a whole suite of ready-to-use classes for fast responsive layouts. | Sass mixins |
| Using a single set of .col-sm-* classes, you can create a basic grid system that starts out stacked before becoming horizontal with at the small breakpoint (sm). | Stacked to horizontal |
| Responsive classes Bootstrap’s grid includes five tiers of predefined classes for building complex responsive layouts. Customize the size of your columns on extra small, small, medium, large, or extra large devices however you see fit. t/f | t |
| In a grid layout, content must be placed within columns and only columns may be immediate children of rows. t or f | t |
| Bootstrap’s grid system uses a series of containers, rows, and columns to layout and align content. t or f | t |

| Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages. | Alerts |
| Approach Additional styling is done only with classes. For example, we reboot some <table> styles for a simpler baseline and later provide .table, .table-bordered, and more. t or f | f |
| The box-sizing is globally set on every element—including *::before and *::after, to border-box. This ensures that the declared width of element is never exceeded due to padding or border. t or f | t |

| Variables Variables and maps determine the number of columns, the gutter width, and the media query point at which to begin floating columns. t/f | t |
| Variables We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below. t/f | t |
| Mix and match Don’t want your columns to simply stack in some grid tiers? Use a combination of different classes for each tier as needed. See the example below for a better idea of how it all works. t/f | t |
| All breakpoints For grids that are the same from the smallest of devices to the largest, use the .col and .col-* classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to .col. t/f | t |
| Column breaks Breaking columns to a new line in flexbox requires a small hack: add an element with width: 100% wherever you want to wrap your columns to a new line. t/f | t |
| Column breaks Normally this is accomplished with multiple .rows, but not every implementation method can account for this. t/f | t |

| Be aware of the limitations and bugs around flexbox, like the inability to use some HTML elements as flex containers. Group of answer choices True False | t |
| To make the grid responsive, there are six grid breakpoints, one for each responsive breakpoint: all breakpoints (extra small), small, medium, large, and extra large. t/f | f |
| Use .container for a non-responsive pixel width or .container-fluid for width: 100% across all viewport and device sizes. Group of answer choices True False | f |
| Rows are wrappers for columns. t/f | t |
| Grid System, use our powerful Desktop-first flexbox grid to build layouts of all shapes and sizes. Group of answer choices True False | f |
| Bootstrap primarily uses the following media query ranges or breakpoints in our source Sass files for our layout, grid system, and components. Group of answer choices True False | true |
| Carousel A slideshow component for cycling through elements—images or slides of text—like a carousel. Group of answer choices True False | t |
| Bootstrap’s responsive styles are built to be responsive, an approach that’s often referred to as mobile-first. We use this term in our docs and largely agree with it, but at times it can be too broad. Group of answer choices True False | t |

| Z-index Several Bootstrap components utilize z-index, the CSS property that helps control layout by providing a third axis to arrange content. t.f | t |
| Z-index We utilize a default z-index scale in Bootstrap that’s been designed to properly layer navigation, tooltips and popovers, modals, and more. | t |
| Collapse Toggle the visibility of content across your project with a few classes and our JavaScript plugins. Group of answer choices True False | t |

| The responsive grid system isn’t a framework. It’s not a boilerplate either. It’s a quick, easy, and flexible way to create a responsive website | responsive grid system |

| Thanks to flexbox, grid columns without a specified width will automatically layout as equal width columns. t/f | t |
| While Bootstrap uses ems or rems for defining most sizes, pxs 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 options |
| Utilize breakpoint-specific column classes for easy column sizing without an explicit numbered class like .col-sm-6. | auto-layout columns |
| For example, here are two grid layouts that apply to every device and viewport, from xs to xl. Add any number of unit-less classes for each breakpoint you need and every column will be the same width. | equal-width |
| Auto-layout for flexbox grid columns also means you can set the width of one column and have the sibling columns automatically resize around it. | setting one column width |
| Create equal-width columns that span multiple rows by inserting a .w-100 where you want the columns to break to a new line. Make the breaks responsive by mixing the .w-100 with some responsive display utilities. \ | equal-width multi-row |
| Use flexbox alignment utilities to vertically and horizontally align columns. | alignment |
| The gutters between columns in our predefined grid classes can be removed with .no-gutters. This removes the negative margins from .row and the horizontal padding from all immediate children columns. | no gutters |
| If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line. | column wrapping |
| 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. | order classes |
| You can offset grid columns in two ways: our responsive .offset- grid classes and our margin utilities. Grid classes are sized to match columns while margins are more useful for quick layouts where the width of the offset is variable. | off-setting columns |
| 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. | offset classes |
| With the move to flexbox in v4, you can use margin utilities like .mr-auto to force sibling columns away from one another. | margin utilities |
| To nest your content with the default grid, add a new .row and set of .col-sm-* columns within an existing .col-sm-* column. Nested rows should include a set of columns that add up to 12 or fewer (it is not required that you use all 12 available columns) | nesting |
| Variables and maps determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below. t/f | t |
