Default styles
Individual form controls receive styling, but without any required base class on the <form>
or large changes in markup. Results in stacked, left-aligned labels on top of form controls.
- <form>
- <fieldset>
- <legend>Legend</legend>
- <label>Label name</label>
- <input type="text" placeholder="Type something…">
- <span class="help-block">Example block-level help text here.</span>
- <label class="checkbox">
- <input type="checkbox"> Check me out
- </label>
- <button type="submit" class="btn">Submit</button>
- </fieldset>
- </form>
Optional layouts
Included with Bootstrap are three optional form layouts for common use cases.
Search form
Add .form-search
to the form and .search-query
to the <input>
for an extra-rounded text input.
- <form class="form-search">
- <input type="text" class="input-medium search-query">
- <button type="submit" class="btn">Search</button>
- </form>
Inline form
Add .form-inline
for left-aligned labels and inline-block controls for a compact layout.
- <form class="form-inline">
- <input type="text" class="input-small" placeholder="Email">
- <input type="password" class="input-small" placeholder="Password">
- <label class="checkbox">
- <input type="checkbox"> Remember me
- </label>
- <button type="submit" class="btn">Sign in</button>
- </form>
Horizontal form
Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:
- Add
.form-horizontal
to the form - Wrap labels and controls in
.control-group
- Add
.control-label
to the label - Wrap any associated controls in
.controls
for proper alignment
- <form class="form-horizontal">
- <div class="control-group">
- <label class="control-label" for="inputEmail">Email</label>
- <div class="controls">
- <input type="text" id="inputEmail" placeholder="Email">
- </div>
- </div>
- <div class="control-group">
- <label class="control-label" for="inputPassword">Password</label>
- <div class="controls">
- <input type="password" id="inputPassword" placeholder="Password">
- </div>
- </div>
- <div class="control-group">
- <div class="controls">
- <label class="checkbox">
- <input type="checkbox"> Remember me
- </label>
- <button type="submit" class="btn">Sign in</button>
- </div>
- </div>
- </form>
Supported form controls
Examples of standard form controls supported in an example form layout.
Inputs
Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.
Requires the use of a specified type
at all times.
- <input type="text" placeholder="Text input">
Textarea
Form control which supports multiple lines of text. Change rows
attribute as necessary.
- <textarea rows="3"></textarea>
Checkboxes and radios
Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.
Default (stacked)
- <label class="checkbox">
- <input type="checkbox" value="">
- Option one is this and that—be sure to include why it's great
- </label>
- <label class="radio">
- <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
- Option one is this and that—be sure to include why it's great
- </label>
- <label class="radio">
- <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
- Option two can be something else and selecting it will deselect option one
- </label>
Inline checkboxes
Add the .inline
class to a series of checkboxes or radios for controls appear on the same line.
- <label class="checkbox inline">
- <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
- </label>
- <label class="checkbox inline">
- <input type="checkbox" id="inlineCheckbox2" value="option2"> 2
- </label>
- <label class="checkbox inline">
- <input type="checkbox" id="inlineCheckbox3" value="option3"> 3
- </label>
Selects
Use the default option or specify a multiple="multiple"
to show multiple options at once.
- <select>
- <option>1</option>
- <option>2</option>
- <option>3</option>
- <option>4</option>
- <option>5</option>
- </select>
- <select multiple="multiple">
- <option>1</option>
- <option>2</option>
- <option>3</option>
- <option>4</option>
- <option>5</option>
- </select>
Extending form controls
Adding on top of existing browser controls, Bootstrap includes other useful form components.
Prepended and appended inputs
Add text or buttons before or after any text-based input. Do note that select
elements are not supported here.
Default options
Wrap an .add-on
and an input
with one of two classes to prepend or append text to an input.
- <div class="input-prepend">
- <span class="add-on">@</span>
- <input class="span2" id="prependedInput" type="text" placeholder="Username">
- </div>
- <div class="input-append">
- <input class="span2" id="appendedInput" type="text">
- <span class="add-on">.00</span>
- </div>
Combined
Use both classes and two instances of .add-on
to prepend and append an input.
- <div class="input-prepend input-append">
- <span class="add-on">$</span>
- <input class="span2" id="appendedPrependedInput" type="text">
- <span class="add-on">.00</span>
- </div>
Buttons instead of text
Instead of a <span>
with text, use a .btn
to attach a button (or two) to an input.
- <div class="input-append">
- <input class="span2" id="appendedInputButton" type="text">
- <button class="btn" type="button">Go!</button>
- </div>
- <div class="input-append">
- <input class="span2" id="appendedInputButtons" type="text">
- <button class="btn" type="button">Search</button>
- <button class="btn" type="button">Options</button>
- </div>
Button dropdowns
- <div class="input-append">
- <input class="span2" id="appendedDropdownButton" type="text">
- <div class="btn-group">
- <button class="btn dropdown-toggle" data-toggle="dropdown">
- Action
- <span class="caret"></span>
- </button>
- <ul class="dropdown-menu">
- ...
- </ul>
- </div>
- </div>
- <div class="input-prepend">
- <div class="btn-group">
- <button class="btn dropdown-toggle" data-toggle="dropdown">
- Action
- <span class="caret"></span>
- </button>
- <ul class="dropdown-menu">
- ...
- </ul>
- </div>
- <input class="span2" id="prependedDropdownButton" type="text">
- </div>
- <div class="input-prepend input-append">
- <div class="btn-group">
- <button class="btn dropdown-toggle" data-toggle="dropdown">
- Action
- <span class="caret"></span>
- </button>
- <ul class="dropdown-menu">
- ...
- </ul>
- </div>
- <input class="span2" id="appendedPrependedDropdownButton" type="text">
- <div class="btn-group">
- <button class="btn dropdown-toggle" data-toggle="dropdown">
- Action
- <span class="caret"></span>
- </button>
- <ul class="dropdown-menu">
- ...
- </ul>
- </div>
- </div>
Segmented dropdown groups
- <form>
- <div class="input-prepend">
- <div class="btn-group">...</div>
- <input type="text">
- </div>
- <div class="input-append">
- <input type="text">
- <div class="btn-group">...</div>
- </div>
- </form>
Search form
- <form class="form-search">
- <div class="input-append">
- <input type="text" class="span2 search-query">
- <button type="submit" class="btn">Search</button>
- </div>
- <div class="input-prepend">
- <button type="submit" class="btn">Search</button>
- <input type="text" class="span2 search-query">
- </div>
- </form>
Control sizing
Use relative sizing classes like .input-large
or match your inputs to the grid column sizes using .span*
classes.
Block level inputs
Make any <input>
or <textarea>
element behave like a block level element.
- <input class="input-block-level" type="text" placeholder=".input-block-level">
Relative sizing
- <input class="input-mini" type="text" placeholder=".input-mini">
- <input class="input-small" type="text" placeholder=".input-small">
- <input class="input-medium" type="text" placeholder=".input-medium">
- <input class="input-large" type="text" placeholder=".input-large">
- <input class="input-xlarge" type="text" placeholder=".input-xlarge">
- <input class="input-xxlarge" type="text" placeholder=".input-xxlarge">
Heads up! In future versions, we’ll be altering the use of these relative input classes to match our button sizes. For example, .input-large
will increase the padding and font-size of an input.
Grid sizing
Use .span1
to .span12
for inputs that match the same sizes of the grid columns.
- <input class="span1" type="text" placeholder=".span1">
- <input class="span2" type="text" placeholder=".span2">
- <input class="span3" type="text" placeholder=".span3">
- <select class="span1">
- ...
- </select>
- <select class="span2">
- ...
- </select>
- <select class="span3">
- ...
- </select>
For multiple grid inputs per line, use the .controls-row
modifier class for proper spacing. It floats the inputs to collapse white-space, sets the proper margins, and clears the float.
- <div class="controls">
- <input class="span5" type="text" placeholder=".span5">
- </div>
- <div class="controls controls-row">
- <input class="span4" type="text" placeholder=".span4">
- <input class="span1" type="text" placeholder=".span1">
- </div>
- ...
Uneditable inputs
Present data in a form that’s not editable without using actual form markup.
- <span class="input-xlarge uneditable-input">Some value here</span>
Form actions
End a form with a group of actions (buttons). When placed within a .form-actions
, the buttons will automatically indent to line up with the form controls.
- <div class="form-actions">
- <button type="submit" class="btn btn-primary">Save changes</button>
- <button type="button" class="btn">Cancel</button>
- </div>
Help text
Inline and block level support for help text that appears around form controls.
Inline help
- <input type="text"><span class="help-inline">Inline help text</span>
Block help
- <input type="text"><span class="help-block">A longer block of help text that breaks onto a new line and may extend beyond one line.</span>
Form control states
Provide feedback to users or visitors with basic feedback states on form controls and labels.
Input focus
We remove the default outline
styles on some form controls and apply a box-shadow
in its place for :focus
.
- <input class="input-xlarge" id="focusedInput" type="text" value="This is focused...">
Invalid inputs
Style inputs via default browser functionality with :invalid
. Specify a type
, add the required
attribute if the field is not optional, and (if applicable) specify a pattern
.
This is not available in versions of Internet Explorer 7-9 due to lack of support for CSS pseudo selectors.
- <input class="span3" type="email" required>
Disabled inputs
Add the disabled
attribute on an input to prevent user input and trigger a slightly different look.
- <input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Validation states
Bootstrap includes validation styles for error, warning, info, and success messages. To use, add the appropriate class to the surrounding .control-group
.
- <div class="control-group warning">
- <label class="control-label" for="inputWarning">Input with warning</label>
- <div class="controls">
- <input type="text" id="inputWarning">
- <span class="help-inline">Something may have gone wrong</span>
- </div>
- </div>
- <div class="control-group error">
- <label class="control-label" for="inputError">Input with error</label>
- <div class="controls">
- <input type="text" id="inputError">
- <span class="help-inline">Please correct the error</span>
- </div>
- </div>
- <div class="control-group info">
- <label class="control-label" for="inputInfo">Input with info</label>
- <div class="controls">
- <input type="text" id="inputInfo">
- <span class="help-inline">Username is already taken</span>
- </div>
- </div>
- <div class="control-group success">
- <label class="control-label" for="inputSuccess">Input with success</label>
- <div class="controls">
- <input type="text" id="inputSuccess">
- <span class="help-inline">Woohoo!</span>
- </div>
- </div>
