The float label pattern floats the inline label up above the input after the user focuses on the form field or enters a value.

For production, use the files from the dist/ folder.



Use one of the following methods to add Float Labels to your project:


Load the dist/float-labels.css and dist/float-labels.min.js files somewhere on your page and then trigger the plugin as follows:

// You may pass in a CSS selector, an HTMLElement or a DomList
var floatlabels = new FloatLabels( 'form', {
    // options go here,

To re-initialize Float Labels after it has already been initialized (e.g. form fields have changed with ajax):


To fully remove Float Labels, including all attached Event Listeners:


HTML markup

Make sure your HTML markup is valid. Your form fields must have labels, the labels must have the for attribute which should have the same value as the field id attribute. Also input fields must have a type attribute.

<label for="input-1">Enter a title</label>
<input type="text" id="input-1"/>

<label for="textarea-1">Enter some content</label>
<textarea id="textarea-1" placeholder="Placeholders are optional"></textarea>

<label for="select-1">Select an option</label>
<select id="select-1">
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>
    <option value="3">Option 3</option>


Default options

    customEvent      : null,
    customLabel      : null,
    customPlaceholder: null,
    exclude          : '.no-label',
    inputRegex       : /email|number|password|search|tel|text|url/,
    prefix           : 'fl-',
    prioritize       : 'label',
    requiredClass    : 'required',
    style            : 0,
    transform        : 'input, select, textarea',
  1. Float Labels first looks at the transform option to know which element tags to transform.
  2. Next, it filters all INPUT elements by the type found by the inputRegex option.
  3. Finally, any resulting elements found in the exclude option are discarded.


Type: Function

This function is run immediately after an element has been transformed by float-labels.

customEvent: function( el ) {
    // do something


Type: Function

This function lets you modify the generated label text; it must return a string value.

customLabel: function( labelEl, el ) {
    return labelEl.textContent;


Type: Function

This function lets you modify the generated placeholder text; it must return a string value.

customPlaceholder: function( placeholderText, el, labelEl ) {
    return placeholderText;


Type: String

A comma-separated string of DOM selector elements to exclude.


Type: Regex

Regex of INPUT types to transform.


Type: String

The prefix of all the Float Label CSS classes.

If you change the prefix, you will need to either write your own custom CSS, or change the prefix option in the SCSS to match.


Type: String

Choose to prioritize either the label or placeholder text as the floating-label.


Type: String

The class name of required elements (if not using the required attribute).


Type: Number|String

Choose the style to use, the default value is either 0, 1, or 2. This is used to create the Float Labels style classname (i.e. .fl-style-1). If you have created your own CSS style (i.e. .fl-style-custom), enter it here (i.e. custom).


Type: String

A comma-separated string of DOM elements to transform. Available options are: input, select, and textarea.


float-labels.js uses yarn to manage package dependencies and gulp to build from src/.

$ yarn
$ gulp

The compiled files will be saved in the dist/ folder.

Style Customization

Sass is used to build the stylesheet so you can @import the src/float-labels.scss file to compile it directly into your Sass project.

Following are the default sass values for Float Labels, they are contained in a map variable.

$float-labels-defaults: (
    base-height             : 24px,
    base-padding            : 6px,
    border-radius           : 3px,
    border-width            : 1px,
    margin-bottom           : 24px,
    color-background        : #fff,
    color-background-active : #fff,
    color-background-focus  : #fff,
    color-border            : #dfdfdf,
    color-border-active     : #dfdfdf,
    color-border-focus      : #1976D2,
    color-placeholder       : #bbb,
    color-required          : #D32F2F,
    color-text              : #444,
    color-text-focus        : #1976D2,
    line-height             : 1.5,
    font-size               : 16px,
    font-size-small         : 12px,
    font-weight             : 400,
    parent                  : '',
    prefix                  : 'fl-',
    transition-easing       : ease-in-out,
    transition-speed        : 0.2s,

To override any values with your own, simply create a new $float-labels map variable and include only the values you wish to change.

Important: Make sure you define $float-labels before you import the src/float-labels.scss file:

$float-labels: (
    border-radius      : 0,
    border-width       : 2px,
    color-border-focus : #009688,
    color-text-focus   : #009688,
    font-weight        : 700,

@import "../../node_modules/float-labels.js/src/float-labels"

How to change CSS style priority

Sometimes existing CSS stylesheet rules will override the styling of Float Labels. To solve this problem, you can specify a "parent" option in the $float-labels map variable. This option value should be property such as an existing #id definition with a high priority/specificity.

In the following example, all Float Labels css rules will begin with form#my-form:

$float-labels: (
    parent: 'form#my-form',

The CSS rule .fl-form label.fl-label { ... } now becomes form#my-form.fl-form label.fl-label { ... }.
