CSS How to Make a Website CSS: Cascading Style Sheets Style the Basic Elements

Select the ID wrapper, set it to a max width of 940 pixels, and then center it on the page using the margin property.

a{
  text-decoration: none;
}
wrapper{
  max-width: 940px;
  margin: center;
}

Note: I thought I had the right idea??? Lesson challenge said, ID "wrapper" not sure about this either. I feel dumb to ask for help again but, I'm afraid I haven't enough experience with code to do otherwise.

you select ids using # followed by the name of the id. for instance if I had an id called "someId" I could select it like so:

#someId {

}

also, margin:center wont work. you are going to have to use the auto value for margin like so

margin: 0 auto;

the first value, 0, specifies the top and bottom margin, while the auto value tells the browser to make it so that the left and right margin are equal on both sides, centering it horizontally.

If it's an ID called wrapper you need a # before the name of you ID in your css:

#wrapper {margin: 0 auto;}

then the margin needs to be auto on the right and left side.
