1. Grafico de barras simple

Código CSS:
[css]
.grafico {
position: relative; /* IE is dumb */
width: 200px;
border: 1px solid #B1D632;
padding: 2px;
}
.grafico .barra {
display: block;
position: relative;
background: #B1D632;
text-align: center;
color: #333;
height: 2em;
line-height: 2em;
}
.grafico .barra span {
position: absolute; left: 1em;
}[/css]

Y este es el código html.
Creamos un “div” con la clase “grafico” y dentro del “div grafico” la barra. Así de sencillo!
[html]
<div class="grafico"><strong class="barra" style="width: 24%;">24%</strong></div>
[/html]
Ver los resultados de los graficos.
