Nova is built on Bootstrap – sleek, intuitive, and powerful front-end framework for faster and easier web development. Bootstrap is a renowned framework that features all major design elements. The whole Nova design is built on top of this framework and this gives you the possibility to use all of their elements, when publishing your posts or pages, and you will be certain that they won’t be in conflict with the initial Nova design. Bootstrap is packed with features, but more importantly – really easy to use from everyone! This gives you the power for quick and sleek design of your layouts.
Code
Inline
Wrap inline snippets of code with <code>
.
<section>
should be wrapped as inline.For example, <code><section></code> should be wrapped as inline.
Basic block
Use <pre>
for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.
<p>Sample text here...</p>
<pre> <p>Sample text here...</p> </pre>
Heads up! Be sure to keep code within <pre>
tags as close to the left as possible; it will render all tabs.
You may optionally add the .pre-scrollable
class which will set a max-height of 350px and provide a y-axis scrollbar.

List of supported table HTML elements and how they should be used.
Tag | Description |
---|---|

Forms
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>
Buttons
Default buttons
Button styles can be applied to anything with the .btn
class applied. However, typically you’ll want to apply these to only <a>
and <button>
elements for the best rendering.
Button | class=”" | Description |
---|---|---|
btn |
Standard gray button with gradient | |
btn btn-primary |
Provides extra visual weight and identifies the primary action in a set of buttons | |
btn btn-info |
Used as an alternative to the default styles | |
btn btn-success |
Indicates a successful or positive action | |
btn btn-warning |
Indicates caution should be taken with this action | |
btn btn-danger |
Indicates a dangerous or potentially negative action | |
btn btn-inverse |
Alternate dark gray button, not tied to a semantic action or use | |
btn btn-link |
Deemphasize a button by making it look like a link while maintaining button behavior |
Cross browser compatibility
IE9 doesn’t crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button
elements, rendering text gray with a nasty text-shadow that we cannot fix.
Button sizes
Fancy larger or smaller buttons? Add .btn-large
, .btn-small
, or .btn-mini
for additional sizes.
<p> <button class="btn btn-large btn-primary" type="button">Large button</button> <button class="btn btn-large" type="button">Large button</button> </p> <p> <button class="btn btn-primary" type="button">Default button</button> <button class="btn" type="button">Default button</button> </p> <p> <button class="btn btn-small btn-primary" type="button">Small button</button> <button class="btn btn-small" type="button">Small button</button> </p> <p> <button class="btn btn-mini btn-primary" type="button">Mini button</button> <button class="btn btn-mini" type="button">Mini button</button> </p>
Create block level buttons—those that span the full width of a parent— by adding .btn-block
.
<button class="btn btn-large btn-block btn-primary" type="button">Block level button</button> <button class="btn btn-large btn-block" type="button">Block level button</button>
Disabled state
Make buttons look unclickable by fading them back 50%.
Anchor element
Add the .disabled
class to <a>
buttons.
<a href="#" class="btn btn-large btn-primary disabled">Primary link</a> <a href="#" class="btn btn-large disabled">Link</a>
Heads up!
We use .disabled
as a utility class here, similar to the common .active
class, so no prefix is required. Also, this class is only for aesthetic; you must use custom JavaScript to disable links here.
Button element
Add the disabled
attribute to <button>
buttons.
<button type="button" class="btn btn-large btn-primary disabled" disabled="disabled">Primary button</button> <button type="button" class="btn btn-large" disabled>Button</button>
One class, multiple tags
Use the .btn
class on an <a>
, <button>
, or <input>
element.
<a class="btn" href="">Link</a> <button class="btn" type="submit">Button</button> <input class="btn" type="button" value="Input"> <input class="btn" type="submit" value="Submit">
As a best practice, try to match the element for your context to ensure matching cross-browser rendering. If you have an input
, use an <input type="submit">
for your button.
Images
Add classes to an <img>
element to easily style images in any project.
<img src="..." class="img-rounded"> <img src="..." class="img-circle"> <img src="..." class="img-polaroid">
Heads up! .img-rounded
and .img-circle
do not work in IE7-8 due to lack of border-radius
support.
Icons by Glyphicons
Icon glyphs
140 icons in sprite form, available in dark gray (default) and white, provided by Glyphicons.
Glyphicons attribution
Glyphicons Halflings are normally not available for free, but an arrangement between Bootstrap and the Glyphicons creators have made this possible at no cost to you as developers. As a thank you, we ask you to include an optional link back to Glyphicons whenever practical.
How to use
All icons require an <i>
tag with a unique class, prefixed with icon-
. To use, place the following code just about anywhere:
<i class="icon-search"></i>
There are also styles available for inverted (white) icons, made ready with one extra class. We will specifically enforce this class on hover and active states for nav and dropdown links.
<i class="icon-search icon-white"></i>
Heads up!
When using beside strings of text, as in buttons or nav links, be sure to leave a space after the <i>
tag for proper spacing.
Icon examples
Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.
Buttons
Button group in a button toolbar
<div class="btn-toolbar"> <div class="btn-group"> <a class="btn" href="#"><i class="icon-align-left"></i></a> <a class="btn" href="#"><i class="icon-align-center"></i></a> <a class="btn" href="#"><i class="icon-align-right"></i></a> <a class="btn" href="#"><i class="icon-align-justify"></i></a> </div> </div>
