Display an image in place of a check mark with codeigniter - codeigniter

Question

I found this code on here. Does anyone know if this would work with codeigniter. I want the ability for some to click on a image and perform the same function as a check box. After you click the image it would display a new image overlay that would be a check mark on top of the image.
Code I found.
input[type=checkbox] {
display: block;
width: 30px;
height: 30px;
background-repeat: no-repeat;
background-position: center center;
background-size: contain;
-webkit-appearance: none;
outline: 0;
}
input[type=checkbox]:checked {
background-image: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" x="0px" y="0px" viewBox="0 0 512 512" enable-background="new 0 0 512 512" xml:space="preserve"><path id="checkbox-3-icon" fill="#000" d="M81,81v350h350V81H81z M227.383,345.013l-81.476-81.498l34.69-34.697l46.783,46.794l108.007-108.005 l34.706,34.684L227.383,345.013z"/></svg>');
}
input[type=checkbox]:not(:checked) {
background-image: url('data:image/svg+xml;utf8,<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 512 512" enable-background="new 0 0 512 512" xml:space="preserve"> <path id="checkbox-9-icon" d="M391,121v270H121V121H391z M431,81H81v350h350V81z"></path> </svg>');
}
<input type="checkbox" id="check" />
<div></div>
