I found this cool style here on stackoverflow link but I didn't know how to apply it to the chekcbox from angular-ui, well they're labels.
I tried adding them as classes, the effect has changed but the active class keep on messing up everything, and they looked weird.
Here is the working plunkr...http://plnkr.co/edit/6CFc73JZTWujUQWnTrWr?p=preview
Basically just add this CSS,
.btn-primary {
background: url('http://lorempixel.com/output/people-q-c-50-50-1.jpg') no-repeat;
height: 50px;
width: 50px;
display: block;
border-radius: 50%;
position: relative;
transition: all 0.4s;
border: solid 5px #FFF;
box-shadow: 0 0 1px #FFF; /* Soften the jagged edge */
}
/* Provide a border when hovered and when the checkbox before it is checked */
.btn-primary:hover,
.btn-primary.active,
.btn-primary:focus{
border: solid 5px #F00;
box-shadow: 0 0 1px #F00; /* Soften the jagged edge */
}
/*
- Create a pseudo element :after when checked and provide a tick
- Center the content
*/
.btn-primary.active::after {
content: '\2714'; /*content is required, though it can be empty - content: '';*/
display: block;
height: 1.5em;
width: 1em;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
margin: auto;
color: #F00;
}
.btn-primary.active{
background: url('http://lorempixel.com/output/people-q-c-50-50-1.jpg') no-repeat;
}
whereas in HTML,
<button type="button" class="btn btn-primary" ng-model="singleModel" btn-checkbox btn-checkbox-true="1" btn-checkbox-false="0"></button>
my-custom-btn ` and it will look like <button type="button" class="btn btn-primary my-custom-btn" ng-model="singleModel" btn-checkbox btn-checkbox-true="1" btn-checkbox-false="0"></button> now just replace all the btn-primary in the above CSS with the class my-custom-btn
