BookingSync Styleguide

Basic form

Individual form controls automatically receive some global styling. All textual <input>, <textarea>, and <select> elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.

Don't mix form groups with input groups

Do not mix form groups directly with input groups. Instead, nest the input group inside of the form group.

<form>
  <div class="form-group">
    <label for="exampleInputEmail1">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail1">
  </div>
  <div class="form-group">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword1">
  </div>
  <div class="form-group">
    <label for="exampleTextarea1">Comment</label>
    <textarea class="form-control" id="exampleTextarea1" rows="5"></textarea>
  </div>
  <div class="form-group">
    <label for="exampleInputFile">File input</label>
    <input type="file" id="exampleInputFile">
    <p class="help-block">Example block-level help text here.</p>
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Check me out
    </label>
  </div>
  <button type="submit" class="btn btn-primary">Submit</button>
</form>

Inline form

Add .form-inline to your form (which doesn't have to be a <form>) for left-aligned and inline-block controls.
This only applies to forms within viewports that are at least 768px wide.

May require custom widths

Inputs and selects have `width: 100%;` applied by default in Bootstrap. Within inline forms, we reset that to `width: auto;` so multiple controls can reside on the same line. Depending on your layout, additional custom widths may be required.

Always add labels

Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the `.sr-only` class. There are further alternative methods of providing a label for assistive technologies, such as the `aria-label`, `aria- labelledby` or `title` attribute. If none of these is present, screen readers may resort to using the `placeholder` attribute, if present, but note that use of `placeholder` as a replacement for other labelling methods is not advised.

<form class="form-inline">
  <div class="form-group">
    <label for="exampleInputName2">Name</label>
    <input type="text" class="form-control" id="exampleInputName2">
  </div>
  <div class="form-group">
    <label for="exampleInputEmail2">Email</label>
    <input type="email" class="form-control" id="exampleInputEmail2">
  </div>
  <button type="submit" class="btn btn-primary">Send invitation</button>
</form>

Inline form with checkboxes

<form class="form-inline">
  <div class="form-group">
    <label for="exampleInputEmail3">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail3">
  </div>
  <div class="form-group">
    <label for="exampleInputPassword3">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword3">
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Remember me
    </label>
  </div>
  <button type="submit" class="btn btn-primary">Sign in</button>
</form>

Inline form with input group

<form class="form-inline">
  <div class="form-group">
    <label class="sr-only" for="exampleInputAmount">Amount (in dollars)</label>
    <div class="input-group">
      <div class="input-group-addon">$</div>
      <input type="text" class="form-control" id="exampleInputAmount" placeholder="Amount">
      <div class="input-group-addon">.00</div>
    </div>
  </div>
  <div class="form-group">
    <div class="input-group">
      <div class="input-group-addon">$</div>
      <label for="exampleInputAmountWithLabel">Amount (in dollars)
      </label>
      <input type="text" class="form-control" id="exampleInputAmountWithLabel">
      <div class="input-group-addon">.00</div>
    </div>
  </div>
  <button type="submit" class="btn btn-primary">Transfer cash</button>
</form>

Horizontal form

Not Recommended

BookingSync UI Kit does not recommend using horizontal forms.

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.

Type declaration required

Inputs will only be fully styled if their `type` is properly declared.

Input groups

To add integrated text or buttons before and/or after any text-based <input>, check out the input group component.

<input type="text" class="form-control" placeholder="Text input">

Textarea

Form control which supports multiple lines of text. Change rows attribute as necessary.

<div class="form-group">
  <textarea class="form-control" rows="3"></textarea>
</div>

Checkboxes and radios (stacked)

Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.

Disabled checkboxes and radios

To provide a "not-allowed" cursor on hover of the parent <label>, you'll need to add the .disabled class to the parent .radio, .radio-inline, .checkbox, or .checkbox-inline.

<div class="checkbox">
  <label>
    <input type="checkbox" value="">
    Option one is this and that&mdash;be sure to include why it's great
  </label>
</div>
<div class="checkbox">
  <label>
    <input type="checkbox" value="" disabled>
    Option two is disabled
  </label>
</div>

<div class="radio">
  <label>
    <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
    Option one is this and that&mdash;be sure to include why it's great
  </label>
</div>
<div class="radio">
  <label>
    <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
    Option two can be something else and selecting it will deselect option one
  </label>
</div>
<div class="radio ">
  <label>
    <input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
    Option three is disabled
  </label>
</div>

Inline checkboxes and radios

Use the .checkbox-inline or .radio-inline classes on a series of checkboxes or radios for controls that 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>

<label class="radio-inline">
  <input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
<label class="radio-inline">
  <input type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2"> 2
</label>
<label class="radio-inline">
  <input type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3"> 3
</label>

Checkboxes and radios without label text

Should you have no text within the <label>, the input is positioned as you'd expect. Remember to still provide some form of label for assistive technologies (for instance, using aria-label).

Limitation

Currently only works on non-inline checkboxes and radios.

<div class="checkbox">
  <label>
    <input type="checkbox" id="blankCheckbox" value="option1" aria-label="...">
  </label>
</div>
<div class="radio">
  <label>
    <input type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="...">
  </label>
</div>

Select

Note that many native select menus—namely in Safari and Chrome—have rounded corners that cannot be modified via border-radius properties.

Chosen

Using Chosen is recommended for a better design and improved experience. More details in the Chosen component.

<div class="select">
  <div class="form-group">
    <label for="destination">Destination</label>
    <select class="form-control" id="destination">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </div>
</div>

Multiple Select

For <select> controls with the multiple attribute, multiple options are shown by default.

Chosen

Using Chosen is recommended for a better design and improved experience. More details in the Chosen component.

<div class="select">
  <div class="form-group">
    <label for="destinations">Destinations</label>
    <select multiple class="form-control" id="destinations">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </div>
</div>

Static control

When you need to place plain text next to a form label within a form, use the .form-control-static class on a <p>.

<form class="form-inline">
  <div class="form-group">
    <label class="sr-only">Email</label>
    <p class="form-control-static">email@example.com</p>
  </div>
  <div class="form-group">
    <label for="inputPassword2" class="sr-only">Password</label>
    <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
  </div>
  <button type="submit" class="btn btn-default">Confirm identity</button>
</form>

Focus state

We remove the default outline styles on some form controls and adjust labels and border-bottom placement and color for :focus.

Demo `:focus` state

The above example forces the focused class normally set by javascript on the .form-group parent to demonstrate the :focus state on a .form-group .form-control.

Disabled fieldsets

Add the disabled attribute to a <fieldset> to disable all the controls within the <fieldset> at once.

Caveat about link functionality of `<a>`

By default, browsers will treat all native form controls (<input>, <select> and `<button>` elements) inside a <fieldset disabled> as disabled, preventing both keyboard and mouse interactions on them. However, if your form also includes <a ... class="btn btn-*"> elements, these will only be given a style of pointer-events: none. As noted in the section about disabled state for buttons (and specifically in the sub-section for anchor elements), this CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11, and won't prevent keyboard users from being able to focus or activate these links. So to be safe, use custom JavaScript to disable such links.

Cross-browser compatibility

While Bootstrap will apply these styles in all browsers, Internet Explorer 11 and below don't fully support the disabled attribute on a <fieldset>. Use custom JavaScript to disable the fieldset in these browsers.

Help text

Block level help text for form controls.

Associating help text with form controls

Help text should be explicitly associated with the form control it relates to using the aria-describedby attribute. This will ensure that assistive technologies – such as screen readers – will announce this help text when the user focuses or enters the control.

<label for="inputHelpBlock">Input with help text</label>
<input type="text" id="inputHelpBlock" class="form-control" aria-describedby="helpBlock">
...
<span id="helpBlock" class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>

Validation states

Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning, .has-error, or .has-success to the parent element. Any .control-label, .form-control, and .help-block within that element will receive the validation styles.

<div class="form-group has-success">
  <label class="control-label" for="inputSuccess1">Input with success</label>
  <input type="text" class="form-control" id="inputSuccess1" aria-describedby="helpBlock2">
  <span id="helpBlock2" class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
</div>
<div class="form-group has-warning">
  <label class="control-label" for="inputWarning1">Input with warning</label>
  <input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
  <label class="control-label" for="inputError1">Input with error</label>
  <input type="text" class="form-control" id="inputError1">
</div>
<div class="has-success">
  <div class="checkbox">
    <label>
      <input type="checkbox" id="checkboxSuccess" value="option1">
      Checkbox with success
    </label>
  </div>
</div>
<div class="has-warning">
  <div class="checkbox">
    <label>
      <input type="checkbox" id="checkboxWarning" value="option1">
      Checkbox with warning
    </label>
  </div>
</div>
<div class="has-error">
  <div class="checkbox">
    <label>
      <input type="checkbox" id="checkboxError" value="option1">
      Checkbox with error
    </label>
  </div>
</div>

Validation with optional icons

You can also add optional feedback icons with the addition of .has-feedback and the right icon.

Requirements

Feedback icons only work with textual <input class="form-control"> elements.

Icons, labels, and input groups

Manual positioning of feedback icons is required for inputs without a label and for input groups with an add-on on the right. You are strongly encouraged to provide labels for all inputs for accessibility reasons. If you wish to prevent labels from being displayed, hide them with the .sr-only class. If you must do without labels, adjust the top value of the feedback icon. For input groups, adjust the right value to an appropriate pixel value depending on the width of your addon.

<div class="form-group has-success has-feedback">
  <label class="control-label" for="inputSuccess2">Input with success</label>
  <input type="text" class="form-control" id="inputSuccess2" aria-describedby="inputSuccess2Status">
  <span class="glyphicon glyphicon-ok form-control-feedback" aria-hidden="true"></span>
  <span id="inputSuccess2Status" class="sr-only">(success)</span>
</div>
<div class="form-group has-warning has-feedback">
  <label class="control-label" for="inputWarning2">Input with warning</label>
  <input type="text" class="form-control" id="inputWarning2" aria-describedby="inputWarning2Status">
  <span class="glyphicon glyphicon-warning-sign form-control-feedback" aria-hidden="true"></span>
  <span id="inputWarning2Status" class="sr-only">(warning)</span>
</div>
<div class="form-group has-error has-feedback">
  <label class="control-label" for="inputError2">Input with error</label>
  <input type="text" class="form-control" id="inputError2" aria-describedby="inputError2Status">
  <span class="glyphicon glyphicon-remove form-control-feedback" aria-hidden="true"></span>
  <span id="inputError2Status" class="sr-only">(error)</span>
</div>
<div class="form-group has-success has-feedback">
  <div class="input-group">
    <span class="input-group-addon">@</span>
    <label class="control-label" for="inputGroupSuccess1">Input group with success</label>
    <input type="text" class="form-control" id="inputGroupSuccess1" aria-describedby="inputGroupSuccess1Status">
  </div>
  <span class="glyphicon glyphicon-ok form-control-feedback" aria-hidden="true"></span>
  <span id="inputGroupSuccess1Status" class="sr-only">(success)</span>
</div>

Height sizing

Set heights using classes like .input-lg. Create taller or shorter form controls that match button sizes.

<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">

<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>

Horizontal form group sizes

Not Recommended

BookingSync UI Kit does not recommend using horizontal forms.

Column sizing

Set widths using grid column classes like .col-lg-*. Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.

<div class="row">
  <div class="col-xs-2">
    <input type="text" class="form-control" placeholder=".col-xs-2">
  </div>
  <div class="col-xs-3">
    <input type="text" class="form-control" placeholder=".col-xs-3">
  </div>
  <div class="col-xs-4">
    <input type="text" class="form-control" placeholder=".col-xs-4">
  </div>
</div>
