Media query failing to activate

As I delve into utilizing media queries to adjust background images and hide content within a division tag when the screen size exceeds 640px, I'm encountering issues with the functionality. Being new to this concept, I can't shake off the feeling that I must be overlooking something crucial.

    <html>
   <HEAD>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<style type="text/css">
<!--
body {background-color:black; overflow:none;}
-->
</style>
</HEAD>
<body>
@media screen and (min-width:641px) {
body {background:white;background-image:url('http://lib.store.yahoo.net/lib/oberers-flowers/Home-Background-2013a.gif');}
div.desktop {visibility:hidden;}
}
<div class="desktop" style="position:absolute;top:0px;left:0px; z-index:1">
<img border="0" src="http://lib.store.yahoo.net/lib/oberers-flowers/mobile1.jpg" width="100%" height=auto>
<img border="0" src="http://lib.store.yahoo.net/lib/oberers-flowers/mobile2.jpg"  width=100% height=auto>
<img border="0" src="http://lib.store.yahoo.net/lib/oberers-flowers/mobile3.jpg"  width=100% height=auto>
</div> 
</body>
</html>

Answer №1

The reason why the CSS is not working is that it is not enclosed within style tags.

<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<style type="text/css">
<!--
body {background-color:black; overflow:none;}

-->

@media (min-width:641px) {
    body {
        background:white;background-image:url('http://lib.store.yahoo.net/lib/oberers-flowers/Home-Background-2013a.gif');}
        div.desktop {visibility:hidden;
    }
}
</style>

Answer №2

Firstly, remember to enclose your media query within a <style> tag. Additionally, it is advisable to avoid using inline styles (such as the style="" attribute in your HTML code). Instead, consolidate all CSS rules into a separate external stylesheet that can be linked in the head section of your document.

Furthermore, ensure that your media queries are placed after other CSS declarations for consistent styling. The last declaration always takes precedence over previous ones!
