# wrapper dosen't work for me

So i have checked the video several times but i can't still get it right i have even tested it with a class instead of a id but it still dosen't change the images. The CSS is linked correctly.

a { text-decoration: none; }

wrapper {

max-width: 920px; margin: 0 auto; }

Without seeing all of your code, here is a couple of suggestions to try and debug your issue:

  1. Have you labelled the element in the html correctly e.g id="wrapper" or class="wrapper" ?
  2. Make sure to label your element correctly in the css.

if it's an id it should be:

#wrapper {
    max-width: 920px;
    margin: 0 auto;
}

if it's a class it should be:

.wrapper {
    max-width: 920px;
    margin: 0 auto;
}

Hope that helps!!

You need to put a # to select wrapper so it reads #wrapper

a { 
text-decoration: none; 
}

#wrapper {
max-width: 920px; 
margin: 0 auto; 
}
