What am I doing wrong

Question

I'm just started creating a website and am having trouble with the nav bar. I added a background color to it but then when I try to float the unordered list right, the background color disappears. Am I doing something wrong.

this is the css

.nav {font-family: sans-serif;
background-color: #522714 ;
color: white;}

.nav ul {width: 50%;
float: right;}

Answer 1

can't say (coz complete code is not shown) try putting background-color in the ul or li of the nav like this:
nav ul li { padding:10px; float:left;background-color: gray;}
it should work just fine!😊👍

Answer 2

Thank you. Will try that.
