Question about .main-nav a and .main-nav li

what is the difference between listed rules below:

.main-nav a{ padding: 15px; }

.main-nav li{ padding: 15px; }

I understand <a> and <li> tags are inside of main-nav and from my understanding they should give same result but outcome is different. I would appreciate if anybody could help me with this. Thank you!

<header class="main-header"> <div class="container"> <h1 class="name"><a href="#">Best City Guide</a></h1> <ul class="main-nav"> <li><a href="#">ice cream</a></li> <li><a href="#">donuts</a></li> <li><a href="#">tea</a></li> <li><a href="#">coffee</a></li> </ul> </div> </header>

Thank you for any help.

Michele Smolensky — excellent reply, why not post it as an answer instead of a comment? That would allow for voting and for Ashim to possibly mark it as "best answer". If I were a moderator, I would promote it for you.

Reposted as an answer:

So the reason .main-nav a and .main-nav li look different when using padding is their default display properties. Anchor tags are inline by default, which means you can add padding to the left and right, but not to the top and bottom without changing the display property to either inline-block or block. List items on the other hand have a default display of "list-item", which is a block-level item, allowing padding all around the element.

(Sorry this was my first time on the community page and didn't realize there was a difference!)

Yes, but it the example, the display properties of li elements is set to inline into the media queries rule: .name, .main-nav, .main-nav li { display: inline; }.

So why padding apply to li ?
