I have added 

```
<link rel="stylesheet" type="text/css" href="http://blogsoc.org/mail1/style.css/" /> 

```

in the index.html above tag. But my stylesheet is not working. my style.css code is:

```
body
{
background-color: #23314F;
}

main
{
margin: 0 auto;
width: 880px;
background: #FAFAFA;
}

```

What changes should be made?
