Checkbox style changing style on label. How to pack?

Good morning!

I have the following code:

 <div style="float:left;">
   <label class="labelPequeno">Oportunidade</label><input type="checkbox" id="oportunidade" name="oportunidade" />
 </div>

 <div style="width:85px;height:40px; float:left;"></div>    

 <div style="float:left;">
   <label class="labelPequeno">Cobertura</label><input type="checkbox" id="cobertura" name="cobertura" />
 </div>

 <div style="width:85px;height:40px; float:left;"></div>    

 <div style="float:left;">
   <label class="labelPequeno">Suite</label><input type="text" onkeypress="return SomenteNumero(event)" class="typeTextPequeno" maxlength="15" id="suite" name="suite"  /> <br /> <br />
 </div>

The idea is to put in this order:

 1 label + 1 Checkbox + 1 espaço + 1 label + 1 chekbox + 1 espaço + 1 label + 1 type text

I'm using this css to label :

label
{
  width:100px;
  height:40px;
  line-height:40px; 
  display: inline-block;
  vertical-align:middle;
}

and this css to checkbox

input[type=checkbox]
{
  background-color:#CCCCCC;
  width:40px;
  height:40px;
}

The problem is that where% w / o% w / w% are displayed lower than the line.

How to arrange?

problem is in the line that has: chekbox , labeis and Oportunidade
