Enhancing the styling of checkboxes using CSS and Javascript

My Javascript skills have been put to the test with a simple code snippet that customizes checkboxes by hiding them and using background images in CSS to display checks and unchecks. It's a neat trick, but I'm wondering if it's HTML/CSS compliant in terms of accessibility. I want to make sure I'm following best practices, especially when it comes to hiding elements. Here's how my code currently looks:

CSS:

.checked:hover, .unchecked:hover
{
    background-color: #242424;
}
.checked
{
    background-image: url(check.bmp);
    color: #ffb500;
}
.unchecked
{
    background-image: url(unchecked.bmp);
}

HTML:

<label for="cbAll" class="checked" id="lblAll">
<input id="cbAll" type="checkbox" name="cbAll" checked="checked"/>
ALL </label>

Answer №1

If accessibility is a concern for you, I would recommend studying professionally written code from others. One great example to look at is jQuery UI, particularly the code generated by jQuery UI's button widget, which serves as a replacement for checkboxes.

Here is an example of original HTML:

<input type="checkbox" id="check" /><label for="check">Toggle</label>

And here is the generated HTML:

<input type="checkbox" id="check" class="ui-helper-hidden-accessible" />
<label for="check" aria-pressed="false" class="[redacted]" role="button" aria-disabled="false">
    <span class="ui-button-text">Toggle</span>
</label>

It is important to note the adherence to the WAI-RIA specification, with the proper use of the role attribute to define the role of the label element as a button (the original input element is hidden and not read by screen readers). For building accessible elements like this, referring to the specifications is highly recommended.
