Hi, if you want to target id element, you need to put # in front of id name... so it should be #logo and also #wrapper...

It is easy to miss certain mistakes if you write it like this. I gave your code a bit more space, so it is easier to read.

All classes need a . before the selector. All ID's need a # before the selector.

Also I noticed you made some mistakes in commenting out the following comments:

• logo text
• links
• green header

And the a.selected selector does not exist. Maybe you meant a:active?

See below for some changes. I assumed you used ID's, so I gave all selectors a #. If you used a class, you can change the # into a .

/***************************************** GENERAL *****************************************/

#wrapper{
    max-width: 940px; 
    margin: 0 auto; 
    padding: 0 5%; 
}

a { 
    text-decoration: none; 
} 

/***************************************** HEADING *****************************************/

#logo {
    text-align: center; 
    margin: 0; 
}

/***************************************** COLOR ****************************************/

/* site body*/ 
body{ 
    background-color: #fff; 
    color: #999; 
}

/* green header */ 

header{ 
    background-color:#6ab47b; 
    border-color:#599a68 
}

/* nav background on mobile*/ 
#nav{ 
    background-color: #599a68; 
}

/*logo text*/
 h1, h2{ 
    color:#fff; 
}

/* links */ 
a{ 
    color:#6ab47b; 
}

/* nav links*/ 
#nav a, 
#nav a:visited{ 
    color:#fff; 
}

/* selected nav links*/ 
#nav a:active, 
#nav a:hover{ 
    color:#32673f; 
}

I know i copied this from my workspace but Thats not how it looks in workspace. I didnt forget to put the # before ids. Also the links i commented with /* */.Anyways I downloaded the the zip file and compared it to my file. I couldnt spot the difference.

yes, at some point my header div started to go back to the left, even though I put the value center on text-align.
