Button groups Examples Two basic options, along with two more specific variations. Single button group Wrap a series of buttons with .btn in .btn-group . Left Middle Right <div class="btn-group"> <button class="btn">Left</button> <button class="btn">Middle</button> <button class="btn">Right</button> </div> Multiple button groups Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components. 1 2 3 4 5 6 7 8 <div class="btn-toolbar"> <div class="btn-group"> ... </div> </div> Vertical button groups Make a set of buttons appear vertically stacked rather than horizontally. <div class="btn-group btn-group-vertical"> ... </div> Checkbox and radio flavors Button groups can also function as radios, where only one button may be active, or checkboxes, where any number of buttons may be active. View the JavaScript docs for that. Dropdowns in button groups Heads up! Buttons with dropdowns must be individually wrapped in their own .btn-group within a .btn-toolbar for proper rendering.

Thumbnails Grids of images, videos, text, and more Default thumbnails By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.





Highly customizable With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.



Why use thumbnails Thumbnails (previously .media-grid up until v1.4) are great for grids of photos or videos, image search results, retail products, portfolios, and much more. They can be links or static content. Simple, flexible markup Thumbnail markup is simple—a ul with any number of li elements is all that is required. It's also super flexible, allowing for any type of content with just a bit more markup to wrap your contents. Uses grid column sizes Lastly, the thumbnails component uses existing grid system classes—like .span2 or .span3 —for control of thumbnail dimensions. Markup As mentioned previously, the required markup for thumbnails is light and straightforward. Here's a look at the default setup for linked images: <ul class="thumbnails"> <li class="span4"> <a href="#" class="thumbnail"> <img data-src="holder.js/300x200" alt=""> </a> </li> ... </ul> For custom HTML content in thumbnails, the markup changes slightly. To allow block level content anywhere, we swap the <a> for a <div> like so: <ul class="thumbnails"> <li class="span4"> <div class="thumbnail"> <img data-src="holder.js/300x200" alt=""> <h3>Thumbnail label</h3> <p>Thumbnail caption...</p> </div> </li> ... </ul> More examples Explore all your options with the various grid classes available to you. You can also mix and match different sizes.









Alerts Styles for success, warning, and error messages Default alert Wrap any text and an optional dismiss button in .alert for a basic warning alert message. × Warning! Best check yo self, you're not looking too good. <div class="alert"> <button type="button" class="close" data-dismiss="alert">×</button> <strong>Warning!</strong> Best check yo self, you're not looking too good. </div> Dismiss buttons Mobile Safari and Mobile Opera browsers, in addition to the data-dismiss="alert" attribute, require an href="#" for the dismissal of alerts when using an <a> tag. <a href="#" class="close" data-dismiss="alert">×</a> Alternatively, you may use a <button> element with the data attribute, which we have opted to do for our docs. When using <button> , you must include type="button" or your forms may not submit. <button type="button" class="close" data-dismiss="alert">×</button> Dismiss alerts via JavaScript Use the alerts jQuery plugin for quick and easy dismissal of alerts. Options For longer messages, increase the padding on the top and bottom of the alert wrapper by adding .alert-block . × Warning! Best check yo self, you're not looking too good.
