• Then, we create file style.css as CSS3 file, this file is used to save model and property of layout design that we make in file index.html. step to create and save it is same like in creating file index.html

• Then, connect index.html and style.css by using code below on index.html

<link rel="stylesheet" href="style.css" type="text/css">

So, that code above is displayed on index.html like picture below

• Decide layout in index.html by typing code below

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <link rel="stylesheet" href="style.css" type="text/css">
</head>
<body>
<div id="wrapper">
<div id="container">
<nav>MENU</nav> (html comment removed: HTML5 )
</div>
</div>

</body>
</html>

• Give style in index.html
After finishing layout above, add style in style.css for layout in menu.html.

#wrapper{
width:960px;
margin:auto;
border:#F00 1px solid;
}

nav{
height:40px;
width:960px;
float:left;
background:#ff0066;
}

• Open file menu.html on browser, so the picture is displayed like below
ol (ordered list). Change the content of to be like below

<nav> (html comment removed:  HTML 5 )
