Menu
I've got a stylesheet where the intention is to have a fixed navbar which stays at the top of the screen no matter how far you scroll down. For this I've just used position:fixed; - but when I actually scroll down, the #content div overrides it and goes straight over the top (so the navbar stays at the top of the page but is underneath the content div.)
I haven't done any serious CSS coding in years, so I'm a bit rusty - it's probably a very simple solution, so apologies for being so trivial!
style.css
body {
margin:0;
background:#eeeeee;
}
#navbar {
background-color:#990000;
position:fixed;
width:100%;
height:50px;
text-align:center;
vertical-align:middle;
line-height:50px;
top:0px;
}
#navbar a {
color:#fff;
}
#content {
background:#eeeeee;
margin-top:50px;
width:100%;
}
#feed {
background: #fff;
position:absolute;
left:22%;
width:776px;
}
Pages are structured like this:
<body>
<div id="navbar"><?php include core/navbar.php; ?></div>
<div id="content">
<div id="feed">
CONTENT
</div>
</div>
</body>

To create a fixed top menu, use position:fixed and top:0 . Note that the fixed menu will overlay your other content. To fix this, add a margin-top (to the content) that is equal or larger than the height of your menu.
Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element. Use a container element (like <div>) to create the dropdown menu and add the dropdown links inside it. Wrap a <div> element around the button and the <div> to position the dropdown menu correctly with CSS.
Locate the section of the CSS file controlling the navigation bar. Add the following line of code to this section: clear:both; This moves the element below any floated object above it, ensuring that the navigation bar will appear below, and not to the side, of your header.
In order to fix this you need the property z-indexdefined by W3 that specify the level of the element. Try this:
#navbar {
background-color:#990000;
position:fixed;
z-index:1; /*Add this*/
width:100%;
height:50px;
text-align:center;
vertical-align:middle;
line-height:50px;
top:0px;
}
If you're using Bootstrap 4, the .navbar background is clear and can be covered by some elements. Setting the z-index won't work. Use a background color, e.g., .bg-white.
<nav class="navbar fixed-top navbar-expand-sm navbar-light bg-white">
