Underline still showing even though text decoration is set

Question

Even though I have set text-decoration to none, an underline is still showing on the h1 element. If you want to see the full css, go here. I am new to css, and this is just an adapted version of some code I found on the internet, sorry if the problem is obvious. If the problem isn't with the bellow code (which is where I think it probably is) then I will add in other relevant code.

You can see the page this is working on here

#pagetop h1 , a:visited
{
    display:block;
    float:left;
    line-height:90px;
    color:#FFFFFF;
    text-align:left;
    font-size:27px;
    font-weight:bold;
    font-family:Arial, Helvetica, sans-serif;
    float:left;
    margin-left:23px;
    text-decoration:none;
}

Answer 1

Your CSS selector #pagetop h1 , a:visited states that you would like to apply those styles to an h1 and also an a in its visited state.

The comma in your code represents a list of separate selectors rather than a combined selector. In your case you don't need to separately specify the same styles for both the h1 and the a.

What you want to select is an a that is a descendant of an h1 within #pagetop (so that it isn't applied to all h1s):

#pagetop h1 a { text-decoration: none; }

Answer 2

There is text decoration in your link in the h1 tag. Add this style:

h1 a
{
text-decoration:none;
}
