Declaring color: white on ul li Element

What is the point of selecting the Element ul li {color: white}??? This would bring no visible change to the list item in the unordered list since an anchor element would still need to be selected in order to change the color...

It sounds to me like just an example of specificity... what you can do to change the colour of an elements text on a specific instance, in this case a list item or an unordered list. But you can as you suggest override this further by making this a link which has it's own pseudo selectors for targeting links in certain states.

Keep in mind that by default links are unvisited and you can change the colour of an unvisited link with :unvisited pseudo selector. :-)

Jonathan Grieve — can you share an example of how the psuedo class you mentioned would be written out in in a css declaration for changing those links to white? i.e., how/where in the declaration would :unvisited be placed?

Thanks in advance!

Hi Gina.

Unvisited is a way of changing colour based on the "state" of a link. Unvisited would be the default state since when you visit a pafe for the first time you've yet to click on that link.

In practice it would look something like this

a:unvisited {
   color: white;
}

Which is a style that targets any unvisited link on a page.

You can be more specific by targeting links with a specific class or id

a.button-class:unvisited{
  color: white;
}

Anytime you use an element it goes directly at the end preceded by a colon : :visited

Hope this helps. :)

Jonathan Grieve Thanks! I understood the function, just didn't know how to place it in context to the rest of the declaration, so that helps a ton! Thank you. :)
