how do i make this responsive nav bar work properly? - css

Question

i am trying to make a responsive navigation bar with these 4 elements. however, if i drag the browserwindow to a certrain point it starts placing one of the 4 below the rest. but i dont know what i'm doing wrong.
The HTML:
<div id="nav">
<ul>
<li class="blue">Home</li>
<li class="blue">Trailer</li>
<li class="red">Gallery</li>
<li clas="red">Contact Us</li>
</ul>
</div>
The CSS:
#nav {
width: 100%;
background-color:transparant;
}
#nav ul {
width: 85%;
max-width: 1200px;
padding: 0;
margin: 0 auto;
list-style: none;
text-align: center;
}
#nav ul li {
display: inline-table;
width: 24%;
padding: 4px;
background-color:#242424;
border-radius: 5px;
}
#nav ul li a {
color:white;
text-decoration: none;
width: 100%;
padding-top: 10px;
padding-bottom: 10px;
display: inline-block;
border-radius: 5px;
}

Answer 1

You are maybe having problems with your padding.
For that, add the box-sizing property in your lis and the padding will be included in the width of the element, like:
#nav ul li {
display: inline-table;
width: 24%;
padding: 4px;
background-color:#242424;
border-radius: 5px;
box-sizing: border-box;
}

And there's those undesirable white spaces between your lis. In this link, there are some ways to avoid this problem, like font-size:
#nav ul {
font-size: 0;
}
#nav ul li {
font-size: 16px;
}
Give it a try and let me know if it helps!
