 Bootstrap was created at Twitter in mid-2010 by [@mdo](https://twitter.com/mdo) and [@fat](https://twitter.com/fat). Prior to being an open-sourced framework, Bootstrap was known as _Twitter Blueprint_. A few months into development, Twitter held its [first Hack Week](https://blog.twitter.com/2010/hack-week) and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.

With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet.

-Cards require a small amount of markup and classes to provide you with as much control as possible. These classes and markup are flexible though and can typically be remixed and extended with ease. For example, if your card has no flush content like images, feel free to put the `.card-block` class on the `.card` element to consolidate your markup.
+Cards are built with as little markup and styles as possible, but still manage to deliver a ton of control and customization. Built with flexbox, they offer easy alignment and mix well with other Bootstrap components.

+Cards support a wide variety of content, including images, text, list groups, links, and more. Below are examples of what's supported.
+
+### Blocks
+
+The building block of a card is the `.card-block`. Use it whenever you need a padded section within a card.

+### Titles, text, and links
+
+Card titles are used by adding `.card-title` to a `<h*>` tag. In the same way, links are added and placed next to each other by adding `.card-link` to  a `<a>` tag.
+
+Subtitles are used by adding a `.card-subtitle` to an `<h*>` tag. If the `.card-title` and the `.card-subtitle` items are placed in a `.card-block` item, the card title and subtitle are aligned nicely.

-## Groups
+## Card layout
 
-Use card groups to render cards as a single, attached element with equal width and height columns. By default, card groups use `display: table;` and `table-layout: fixed;` to achieve their uniform sizing. However, enabling [flexbox mode]({{ site.baseurl }}/getting-started/flexbox) can switch that to use `display: flex;` and provide the same effect.
+In addition to styling the content within cards, Bootstrap includes a few options for laying out series of cards. For the time being, **these layout options are not yet responsive**.

-## Decks
-
-Need a set of equal width and height cards that aren't attached to one another? Use card decks. By default, card decks require two wrapping elements: `.card-deck-wrapper` and a `.card-deck`. We use table styles for the sizing and the gutters on `.card-deck`. The `.card-deck-wrapper` is used to negative margin out the `border-spacing` on the `.card-deck`.

+### Card columns
+
+Cards can be organized into [Masonry](http://masonry.desandro.com)-like columns with just CSS by wrapping them in `.card-columns`. Cards are built with CSS `column` properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to right.
+
+**Heads up!** Your mileage with card columns may vary. To prevent cards breaking across columns, we must set them to `display: inline-block` as `column-break-inside: avoid` isn't a bulletproof solution yet.

 ## Example
 
+Carousels don't automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they're not explicitly required. Add and customize as you see fit.
+
+Be sure to set a unique id on the `.carousel` for optional controls, especially if you're using multiple carousels on a single page.
+
+### Slides only
+
+Here's a carousel with slides only. Note the presence of the `.d-block` and `.img-fluid` on carousel images to prevent browser default image alignment.

-The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.

 ## Usage
 
-### Multiple carousels
-
-Carousels require the use of an `id` on the outermost container (the `.carousel`) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's `id`, be sure to update the relevant controls.

 ### Via data attributes
 
 Use data attributes to easily control the position of the carousel. `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`.
