how to change template size

[sanil]

in style.css change the width

#custom-doc {
margin:auto;text-align:left;
width:60em; /* !IE */
*width:780px;/* IE */
min-width:780px;
background-color: #ffffff;
}

for example you can change size into 905px you can change like this

 #custom-doc { 
width:69.62em;
*width:67.94em;
min-width:905px;
 margin:auto; 
text-align:left; }
