Tôi có thể thay đổi kích thước hộp kiểm bằng CSS không?

input[type=checkbox]
{
  /* Double-sized Checkboxes */
  -ms-transform: scale(2); /* IE */
  -moz-transform: scale(2); /* FF */
  -webkit-transform: scale(2); /* Safari and Chrome */
  -o-transform: scale(2); /* Opera */
  transform: scale(2);
  padding: 10px;
}

/* Might want to wrap a span around your checkbox text */
.checkboxtext
{
  /* Checkbox text */
  font-size: 110%;
  display: inline;
}

<input  type="checkbox" name="optiona" id="opta" checked />
<span class="checkboxtext">
  Option A
</span>
<input type="checkbox" name="optionb" id="optb" />

<input type="checkbox" name="optionc" id="optc" />
<span class="checkboxtext">
