How do I stop a CSS layout from distorting when zooming in/out?

Question

I've set up a very basic site with a #container div that includes the #navbar and #content. However, when I zoom in or out, the #navbar distorts, if I zoom in the links get pushed down below each other instead of being inline. If I zoom out, too much padding is added between the links. How can I stop this?

HTML:

<div id="navbar">
<ul>
    <li><a href="index.html">Home</a></li>
    <li><a href="top.html">Top</a></li>
    <li><strong><a href="free.html">FREE</a></strong></li>
    <li><a href="photo.html">Photo</a></li>
    <li><a href="about.html">About</a></li>
    <li><a href="contact.html">Contact Us</a></li>
</ul>
</div>

<div id="content">

<p>Some sample text.<p>

</div>


</div>

CSS:

#container {

    position: static;
    background-color: #00bbee;
    margin-left: 20%;
    margin-right: 20%;
    margin-top: 7%;
    margin-bottom: 15%;
    border: 2px solid red;


}

#navbar  ul{

    list-style: none;



}

#navbar  li{

    display: inline;

}

#navbar li a{

    text-decoration: none;
    color: #11ff11;
    margin: 3%;
    border: 1px dotted orange;
    padding-left: 4px;

}

#navbar li a:hover {

    background-color: white;
    color: green;

}

#navbar {

    background-color: #eeeeee;
    padding-top: 2px;
    padding-bottom: 5px;
    border: 1px solid yellow;

}

How can I stop it from distorting?

Also, I'm still pretty new to CSS, I was taught to use % instead of px. Is that right? Also anything else you've got to point out, please let me know.

Thanks in advance!

Answer 1

As this question still gets constant views, I'll post the solution I use currently.

CSS Media Queries:

@media screen and (max-width: 320px) { 

/*Write your css here*/

}

@media screen and (max-width: 800px) { 

}

Answer 2

I had a similar problem that I fixed by adding an extra div around my navigation menu. I then added the following

#menu-container {
    position: absolute;
    white-space: nowrap;
    overflow: hidden;

}

This prevented it from wrapping. Hope it works.
