Usage

HTML

Fld Grd works with one container element and a set of child elements. You can use whatever class names you want and it's also possible to change the data attribute names.

<div class="fld-grd">
    <div data-fld-width="300" data-fld-height="200">
        <img src="300x200.jpg" width="300">
    </div>
    <div data-fld-width="600" data-fld-height="250">
        <img src="600x250.jpg" width="600">
    </div>
    <div data-fld-width="100" data-fld-height="300">
        <img src="100x300.jpg" width="100">
    </div>
</div>

CSS

To show all fluid grid items in a row, you can use float, display: inline-block or flexbox. Grid gutters with margin or padding are also supported.

/**
 * 1. Optional: 10px gutter
 */
.fld-grd {
    margin-right: -5px; /* [1] */
    margin-left: -5px; /* [1] */
}

/**
 * 1. Mandatory: `display: inline-block` or a flexbox based grid system do also work
 * 2. Optional: 10px gutter
 */
.fld-grd > div {
    float: left; /* [1] */
    padding-right: 5px; /* [2] */
    padding-left: 5px; /* [2] */
}

/**
 * 1. Optional: Setting `vertical-align` removes the whitespace that appears below `<img>` elements
 *    when they are dropped into a page as-is
 */
.fld-grd > div > img {
    vertical-align: top; /* [1] */
}

JavaScript

var fldGrd = new FldGrd(document.querySelector('.fld-grd'), {
    /**
     * Maximum row height
     *
     * @type {Integer}
     */
    rowHeight: 250,

    /**
     * Give "orphans" — elements in the last row that do not form a complete row — a specific
     * height. By default, "orphans" will have the average height of the other rows
     *
     * @type   {Function}
     * @param  {Object}   rows
     * @param  {number}   rows.heightAvg Average row height
     * @param  {Array}    rows.heights
     * @return {number}
     */
    rowHeightOrphan: (rows) => Math.round(rows.heightAvg),

    /**
     * CSS Selector for fluid grid items. It's useful if you also have other elements in your
     * container that shouldn't be treated as grid items
     *
     * @type {string}
     */
    itemSelector: '*',

    /**
     * CSS Selector for objects inside grid items. `width` and `height` is applied to this element
     *
     * @type {string}
     */
    objSelector: 'img',

    /**
     * Specify data attribute names that are used to determine the dimensions for each item
     *
     * @type {string}
     */
    dataWidth: 'data-fld-width',
    dataHeight: 'data-fld-height',
});

// Manually update fluid grid
fldGrd.update();

// Destroy `fldGrd` instance
fldGrd.destroy();

Browser Support

All major browsers are supported. If you need to support IE9, you'll have to polyfill requestAnimationFrame.
