1,491 PointsHow is the "class" linked to the action of viewing a specific <a><li> element?
Usually, an element is called upon because it was addressed through code. I don't see that happening with the "class" attribute. How does the code understand that when someone is viewing a specific page it needs to highlight the corresponding <nav> element.

If I missed something, please provide the time index for the part you are looking at that involves class.

1,491 PointsThe section is called "Using Classes in CSS" and it's around 1:39 where he starts implementing the attribute. He then proceeds to call on the 'class' name he assigned the <li> element to signify which page the viewer is currently on. It does this by making the corresponding <nav> link change to the color he assigned.

231,198 PointsI see now, it's not the
nav
being changed there but the anchor (a) element. The CSS is created in the video right after the class is added to the HTML, and the selector is:nav a.selected {
This means "apply this rule to
a
elements that are inside anav
element, and only if they have have the class ofselected
. Since that class is applied to the element that refers to the current page, only that one will be highlighted.
