1,985 PointsI am confused about classes
This is the css that confuses me
nav a.selected, nav a:hover{
color: #32673f;
}
I do not get it we only used the class slected on one hyperlink so shouldnt it only work on that one and why is is it the only one that will not change color when hovered over?also how does it know what webpage you are on at that moment wouldnt it just assume you were on index.html the whole time becausse thats the only one in the class selected
thanks all answers appreciated

nav a .selected,
nav a:hover {
color: #32673f;
}
This code selects 2 different things, the first one is all anchor elements with the class ".selected" and that are children of navigation elements. The second one are all anchor elements that are children of navigation elements while your mouse is hovering over the anchor element (the links).
I'm not too sure what specific question you're asking. If you're asking why you would do this, it's just how the designer wanted to do this. He wanted to use this color for both of those situations.

Full Stack JavaScript Techdegree Graduate 56,501 PointsHi Guy,
The selected class is applied to the HTML page we are currently working on, in this case the index.html homepage.
Later in the course, when we create another page the selected class will be moved to the relevant link on that page.
For Example, if nav element HTML looks like this on the Homepage: <li><a href="index.html" class="selected">Home</a></li> <li><a href="about.html">About</a></li>
It will look like this on the About page: <li><a href="index.html"Home</a></li> <li><a href="about.html" class="selected"> >About</a></li>
In a browser, the About page will have the dark green selected link while the Home link will be white but will highlight dark green when hovered over.

Full Stack JavaScript Techdegree Graduate 56,501 Points"why is is it the only one that will not change color when hovered over" The CSS makes the links change to the dark green colour. As the selected link is already that colour it does not appear to change. "how does it know what webpage you are on at that moment wouldnt it just assume you were on index.html the whole time becausse thats the only one in the class selected" See my answer below about how the "selected" class is moved to the relevant page in the HTML. This is shown in later videos in the course.
Hope this helps.
