As you can see on the image, this is a simple navbar:
.upper-center {
display: flex;
flex-direction: row;
justify-content: space-around;
}
<ul class="upper-center">
<li><a>News</a></li>
<li><a>Solutions</a></li>
<li><a>Forum</a></li>
<li><a>Contact</a></li>
</ul>
Why is this green square taking some of the space from the whole UL element?
