Sorry Emma,
The easiest way to explain how to change it is this:
If you open your home.css stylesheet (which is at: CSSMenuWriter/cssmw_home/menu.css) in DreamWeaver and look at or about line 75, you will see the following block of rules for the outerWrapper div:
#outerWrapper {
background-color: #ffffff;
border-top: solid 5px #ffffff; /* Sets the top border properties for an element using shorthand notation */
margin-left: 4px;
margin-right: 0px;
margin-top: 4px;
text-align: left; /* Redefines the text alignment defined by the body element. */
width: 760px;
}
Change it to this:
#outerWrapper {
background-color: #ffffff;
border-top: solid 5px #ffffff; /* Sets the top border properties for an element using shorthand notation */
margin: 0 auto;
text-align: left; /* Redefines the text alignment defined by the body element. */
width: 760px;
}
Then save your changes.
