Enlarge the size of checkboxes on Phonegap for Android

I'm currently working on a quiz application using Phonegap, incorporating HTML, JavaScript, and CSS without any additional frameworks. My problem lies in the fact that the checkboxes appear too small on Android devices. I attempted to adjust the width and height of input[type=checkbox] to 2em in my CSS, which seemed effective in Chrome and in the emulator, but not when tested on actual devices such as a Samsung S4 Mini or Asus TF101.

These checkboxes are utilized within an unordered list, with the following HTML structure:

<div class="challenge">
  <ul>
    <li><label for="opt0"><input type="checkbox" id="opt0" value="right">Answer A</label></li>
    <li><label for="opt1"><input type="checkbox" id="opt1" value="wrong">Answer B</label></li>
  </ul>
</div>

Below is the relevant CSS code snippet:

body {
  -webkit-touch-callout: none;
  -webkit-text-size-adjust: none;
  -webkit-user-select: none;
  font-family: arial;
  background-color:white;
  height: 100%;
  width: 100%;
  padding: 0;
  margin: 0;
  font-size: medium;
  font-size: 1.5em;
}
.savvy_app {
  position: absolute;
  overflow: auto;
  margin: 0;
  padding: 10px 5px 0 5px;
  top: 73px;
  bottom: 2px;
  max-width: 100%;
  min-width: 98%;
}
input[type=checkbox] {
  width: 2em;
  height: 2em;
}
.challenge ul {
  list-style-type: none;
  padding-left: 10px;
}
.challenge ul li, .results ul li {
  font-family: georgia;
  font-weight: normal;      
  position: relative;
  border: none;
  margin-bottom: 5px;
  padding-bottom: 0;
}
.challenge label, .results label {
  display: block;
  padding-left: 50px;
  padding-top: 5px;
}
.challenge input, .results input {
  display: inline;
  margin-left: -50px;
  position: absolute;
}

What could be causing this issue? Any insights would be greatly appreciated.

Answer №1

Dealing with styling form elements can be quite challenging, especially when it comes to checkboxes and radio buttons across different devices.

One trick is to hide the checkboxes by setting their visibility to hidden or opacity to 0, and then using CSS like input[type=checkbox]:checked to change the background image of a span next to the checkbox. This way, you can create a custom-designed checkbox that switches between two states.

However, there are various compatibility and accessibility concerns associated with this method, so it's important to weigh the pros and cons before implementing it.
