ID Selector Video: I can't get the code to work

According to the video I'm working on, I'm supposed to get a div with ID primary-content to have a red border, but the code doesn't work. What am I missing?

  <h3>From Tents to Resorts</h3>
  <p>
    Lake Tahoe is full of wonderful places to stay. You have the ability to sleep in the outdoors in a tent, or relax like a king at a five star resort. Here are our top three resorts:

  <h3>Pack Accordingly</h3>
  <p>
    One of most important things when it comes to traveling through the great outdoors is packing accordingly. Here are a few tips:

Well now it works. There must have been a long delay from when I saved my work to when I was able to view it.

Hi Kim,

Classes in html are targeted using .classname and id's are targeted in CSS using the #idname.

div class="superman".............. In Css --> .superman { } " div id="catwoman".................... In Css --> #catwoman{ } "

The biggest difference is these two is that a element can have multiple classes, while a 'unique' id is only assigned to a single element. eg". div class="superman batman helium balloon" .............. In Css --> .superman { } .batman{ } .helium{ } .balloon{ } " The div will use all rules in each of the CSS rules you have applied to this div.

However, "div id="catwoman"cannot have any other id assigned to it or to any other element on the page with the id name as catwoman. In CSS--> #catwoman{ } .....note the "#' sign

Finally, this works too "div class=" superman batman helium ballon" id="catwoman" "In this case each individual class and the unique id will share their properties with the div that requested them. Not an ideal way to do things, as specificity can make things in this manner a little complicated.

Hope this helps.
