Experimental forms with CSS

Experimental forms are quite a challenge with CSS. In this case, I've chosen to use an Italian postal order as a template. The markup is as follows:

<div id="bollettino">

<h2><span class="logo">Banco<span>Posta</span></span> CONTI CORRENTI POSTALI - Ricevuta di versamento</h2>

<form action="#" method="post">
<div id="ccn">
<label>sul C/C n.</label>
<table summary="Numero di conto corrente: riempire i campi con i caratteri necessari" id="numerocc1">
<td><input type="text" name="char1" id="char1" size="2" /></td>
<td><input type="text" name="char2" id="char2" size="2" /></td>
<td><input type="text" name="char3" id="char3" size="2" /></td>
<td><input type="text" name="char4" id="char4" size="2" /></td>
<td><input type="text" name="char5" id="char5" size="2" /></td>
<td><input type="text" name="char6" id="char6" size="2" /></td>
<td><input type="text" name="char7" id="char7" size="2" /></td>
<td><input type="text" name="char8" id="char8" size="2" /></td>

<div id="euro">
<label>di Euro</label>
<table summary="Importo da pagare: riempire i campi con le cifre necessarie" id="euro1">
<td><input type="text" name="cifra1" id="cifra1" size="2" /></td>
<td><input type="text" name="cifra2" id="cifra2" size="2" /></td>
<td><input type="text" name="cifra3" id="cifra3" size="2" /></td>
<td><input type="text" name="cifra4" id="cifra4" size="2" /></td>
<td><input type="text" name="cifra5" id="cifra5" size="2" /></td>
<td><input type="text" name="cifra6" id="cifra6" size="2" /></td>
<td><input type="text" name="cifra7" id="cifra7" size="2" /></td>
<td><input type="text" name="cifra8" id="cifra8" size="2" /></td>
<td><input type="text" name="cifra9" id="cifra9" size="2" /></td>
<td><input type="text" name="cifra10" id="cifra10" size="2" /></td>

<div id="importo">
<label for="importolettere">IMPORTO IN LETTERE</label>
<input type="text" name="importolettere" id="importolettere" />

<div id="intestato">
<label for="intestatoa">INTESTATO A</label>
<input type="text" name="intestatoa" id="intestatoa" />

<div id="causa">
<label for="causale">CAUSALE</label>
<input type="text" name="causale" id="causale" />


<div id="eseguito">
<label for="eseguitoda">ESEGUITO DA</label>
<input type="text" name="eseguitoda" id="eseguitoda" />

<div id="via">
<label for="via-piazza">VIA - PIAZZA</label>
<input type="text" name="via-piazza" id="via-piazza" />

<div id="caps">
<label for="cap">CAP</label>
<input type="text" name="cap" id="cap" />
<label for="localita">LOCALITÀ</label>
<input type="text" name="localita" id="localita" />



The CSS code is the following:

/* General styles */

body {
 margin: 2em 0;
 padding: 0;
 background: #fff;
 color: #000;
 font-family: Arial, Helvetica, sans-serif;

#bollettino {
 font-size: 76%;
 margin: 0 auto;
 width: 500px;
 padding-left: 1em;
 border-right: 1px solid #000;

/* Title */

h2 {
 margin: 0;
 font-size: 1em;
 font-weight: normal;
 border-bottom: 1px solid;

span.logo {
 float: right;
 margin: 0;
 padding-right: 1em;
span.logo span {
 font-weight: bold;

/* Form styles */

input {
 border: 1px solid #c00;
 vertical-align: 0;

label {
 font-weight: bold; 
 vertical-align: 5px;

table {
 display: inline;

td, td input {
 width: 18px;
 height: 22px;

#ccn, #euro, 
#importo, #intestato, 
#causa, #eseguito, 
#via, #caps {
 padding-top: 0.5em;

#importo label, #intestato label, 
#eseguito label, #via label, 
#caps label {
 vertical-align: -4px;

#euro1 {
 margin-left: 1.1em;

#importo input, #intestato input,
#eseguito input, #via input, 
#caps input {
 border-width: 0 0 1px 0; 
 border-style: dotted; 
 border-color: #000;

#causa {
 margin-top: 0.8em;
 margin-right: 1em;
 border: 1px solid #000;
 padding-bottom: 2em;

#causa input {
 border-width: 0 0 1px 0;
 border-style: dotted;
 border-color: #000;
 display: block;
 width: 100%;

#causa label {
 background: #fff;
 padding: 3px 3px 3px 0.3em;
 position: relative;
 top: -15px;
 left: 3px;

#bollo {
 margin: 0 1em 0 0;
 padding-top: 100px;
 text-align: right;

#cap {
 margin-right: 0.2em;

Internet Explorer needs the following additional code:

<!--[if IE]>
<style type="text/css">
#importo label, #intestato label, #eseguito label, #via label, #caps label {vertical-align: -3px;}
#causa>input {border-right: 1px solid; position: relative; width: 99.5%;}

Safari and Opera need a couple of JavaScript lines:

window.onload = function () {
  var inputs = document.getElementsByTagName("input");
  for (var i=0; i<inputs.length; i++) {
   if(inputs[i].getAttribute("id") == "causale") {
    if(navigator.userAgent.indexOf("Safari") != -1)  {
     inputs[i].style.width = "99.5%";
    } else if(navigator.userAgent.indexOf("Opera") != -1) {
     inputs[i].style.width = "483px";

You can see the final result here:
