Div height doesn't change in IE8 - html

Question

I have the following code:
<div id="conteudo">
<img id="logo" height="137" width="327" />
<div id="data_hora">
</div>
<div id="nome_patio">
<div id="cor_patio"></div> #NOME_PATIO#
</div>
</div>
css:
body
{
background-color: #000000;
margin: 0;
padding: 0;
font-family:Arial;
}
#conteudo
{
height: 100%;
width: 100%;
}
#data_hora
{
float: right;
font-size: 50px;
color: #E0E428;
margin-top: -90px;
margin-right: 40px;
}
#nome_patio
{
text-align: center;
font-size: 80px;
color: #E0E428;
width: 100%;
font-weight: bold;
}
#cor_patio
{
border: solid 1px #FFFFFF;
height: 10px !important;
width: 80px;
background-color: #E0E428;
margin-right: 20px;
}
So, i'm trying to change the div cor_patio height, but nothing happens... why?
OBS: when i remove font-size from nome_patio, it works fine.

Answer 1

try to set position:absolute; to home_patio, if it doesn't work, also set to cor_patio.

Answer 2

Set position:relative; to #nome_patio and position:absolute; to #cor_patio;
Hope it help.

Answer 3

You need to set your height on #nome_patio to 100%.

Answer 4

I solve the solution with this:
<div id="patio">
<span id="cor_patio"></span><span id="nome_patio">#NOME_PATIO#</span>
</div>
css:
#patio
{
text-align: center;
width: 100%;
}
#cor_patio
{
height: 63px;
width: 63px;
background-color: #E0E428;
margin-right: 30px;
}
#nome_patio
{
font-size: 80px;
color: #E0E428;
font-weight: bold;
}
