makeup-floating-label

Module for creating an accessible, unobtrusive, progressively enhanced floating label.

In a non-javascript state the label will not obscure the textbox; the label will remain in its default floated position above the textbox.

Experimental

This module is still in an experimental state, until it reaches v1 you must consider all minor releases as breaking changes.

Example

import FloatingLabel from 'makeup-floating-label';

// get NodeList
const widgetEls = document.querySelectorAll('.floating-label');

// assign next id to each element
widgetEls.forEach(function(el) {
    var widget = new FloatingLabel(el);
});

Markup:

<div class="floating-label">
    <label class="floating-label__label" for="input-1">Input 1</label>
    <input class="floating-label__textbox" id="input-1" name="input-1" />
</div>

• el: the root widget el
• options.labelElementAnimateModifier: the classname to add when the label begins its CSS animation (default: 'floating-label__label--animate')
• options.labelElementInlineModifier: the classname to add when the label is in its non-floating state (default: 'floating-label__label--inline')
• options.labelElementFocusModifier: the classname to add to the label when the textbox has keyboard focus

An array of RGB values is also supported in the case your textbox background has different colours on focus, invalid, disabled, etc.
