HTML input "box" size on my form too big

[Dawie]

I need to have a small 1 character input "box". I managed to to adjust the height by changing the font-size, but even though I used maxlength=1 and size=1 the box is still too wide. It looks as if 4 characters can fit in there. How can the width as displayed be reduced?

Use CSS to exactly format the input field.

<style>
.box
{
   width : 15px;
   font-family : arial;
   font-size : 12px;
}
</style>
<input type="text" class="box">

adjust the with of the textfield with the width property.
