Question

I cannot change the height of my div with CSS. It does not seem to be taking affect. Code below. I’m coding in C# ASP.NET with Javascipt and CSS. The below code is included in other files using SSI. The height of .navdiv will not alter no matter the value for height:50px.

ASPX

<link rel="Stylesheet" href="CSS/SSI/header.css" />
<div id="header">
    <div id="logo">
        <img id="imglogo" src="Images/logo.gif" />
    </div>
    <div id="nav">
        <a class="navlink" href="default.aspx">
            <div class="navdiv" id="navhome">
                Home
            </div>
        </a>
        <a class="navlink" href="import.aspx">
            <div class="navdiv" id="navimport">
                Import
            </div>
        </a>
    </div>
</div>

Using display: inline-block; will fix the height issue, but if you want the divs to still be side by side, be sure to add float: left; to both elements.
