About code challenge

The key to this question is to understand that the <ul> element has a class of nav, in other words it's <ul class = "nav">.

So the HTML would look something like this:

<ul class="nav">
  <li></li>
</ul>

Now ask yourself ... what is the CSS selector I would use to select all <li>s from the above markup?

If you are unclear on how to do that, consider checking out the Learn HTML & CSS learning adventure.

ul li .nav It would be all li selected with in ul with class nav. But It is a code on Jquery. $("ul li").addClass("nav");

What's the link to the code challenge you are having issues with?

Second challenge

For reference the instructions are:

On the next line, use jQuery to select all list items (li) in an unordered list (ul) with the class of 'nav'?

Note the directions, make no reference to adding a class with JQuery, but instead referencing a class with CSS.

So giving this HTML:

<ul class="nav">
  <li></li>
</ul>

Hint: Use the most specific CSS selector.

Thank you finally I got it
