Adjust the size of iCheck jQuery radio buttons

I have implemented the iCheck Plugin for radio buttons in Angular Directive, but I am facing an issue with resizing the radio button to a smaller size. Does anyone have any suggestions or solutions for this?

Answer №1

It appears that iCheck does not natively support resizing for different sizes. The classes in use seem to be based on png sprite references for button styling. While there are 2x resolution image sprites in the icheck folders, these are likely intended for High-DPI screens.

Your best course of action would be to create new png sprites using a program like Photoshop. Then, you can add a new style definition to either the existing css files or create a new one altogether. This new style should correspond to your larger png file, and adjustments will need to be made for height, width, and positioning to fit the new size requirements.

I have not personally attempted this yet, but I anticipate having to do something similar in the near future to enable larger iCheck radio buttons for mobile devices. A potential approach could involve using a media query to dynamically adjust the size of iCheck elements based on the screen size.

I have duplicated and modified green.css to green-2x.css and it is functioning properly. All you need to do is update the CSS background to [email protected].

$('input.flat-2x').iCheck({
    checkboxClass: 'icheckbox_flat-green-2x',
    radioClass: 'iradio_flat-green-2x'
});
/* iCheck plugin Flat skin, green 2x
----------------------------------- */
.icheckbox_flat-green-2x,
.iradio_flat-green-2x {
    display: inline-block;
    *display: inline;
    vertical-align: middle;
    margin: 0;
    padding: 0;
    width: 40px;
    height: 40px;
    background: url(//cdnjs.cloudflare.com/ajax/libs/iCheck/1.0.2/skins/flat/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f0978295959eb0c288de809e97">[email protected]</a>) no-repeat !important;
    border: none;
    cursor: pointer;
}

.icheckbox_flat-green-2x {
    background-position: 0 0 !important;
}
.icheckbox_flat-green-2x.checked {
    background-position: -44px 0 !important;
}
.icheckbox_flat-green-2x.disabled {
    background-position: -88px 0 !important;
    cursor: default;
}
.icheckbox_flat-green-2x.checked.disabled {
    background-position: -132px 0 !important;
}

.iradio_flat-green-2x {
    background-position: -176px 0 !important;
}
.iradio_flat-green-2x.checked {
    background-position: -220px 0 !important;
}
.iradio_flat-green-2x.disabled {
    background-position: -264px 0 !important;
    cursor: default;
}
.iradio_flat-green-2x.checked.disabled {
    background-position: -308px 0 !important;
}

/* HiDPI support */
@media (-o-min-device-pixel-ratio: 5/4), (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi) {
    .icheckbox_flat-green-2x,
