Tips for Fixing CSS Issues

My HTML / CSS project on JS Fiddle is encountering a few issues jsfiddle ZyBZT.

  • The footer with the class "footer" is not displaying at the bottom of the page.
  • The background image specified by
    url('http://i.imgur.com/z5vCh.png')
    is not showing up.
  • The Sprite Images are failing to appear in the list inside the <UL> element.

Initially, the Sprites were functioning correctly, and no changes were made to the Sprite CSS code, which is shown below:

#nav {
  list-style-type:none;
  margin:20 auto;
  text-shadow:4px 4px 8px #696969;
  white-space:nowrap;
  width:600px;
}
#nav li {
  display: inline-block;
  text-align: center;
  width: 192px;    
}
#nav a {
  background: url('http://i.imgur.com/Sp7jc.gif') 0 -100px no-repeat;
  display: block;
  height: 50px;
  color: Blue;
}
#nav a:hover {
  background-position: 0 -50px;
  color:Red;
}
#nav .active, a:hover {
  background-position: 0 0;        
  color: Black;
}
#nav .active:hover {
  background-position: 0 0;        
  color: Black;
}
#nav span {
  position:relative;
  text-align: center;
  vertical-align: middle;
}
​

Sometimes, the background image loads properly, while other times it doesn't.

Lately, I have been focusing on fixing the FOOTER div, but now more elements seem to be affected by these changes.

How can I troubleshoot when one piece of CSS disrupts another? Is there a way to identify errors in executing CSS?

Answer №1

To improve your coding skills, consider taking the following steps:

  1. Utilize tools like Firebug or your preferred browser developer tools to analyze the applied classes/styles and their effects.
  2. Educate yourself on HTML standards to ensure proper coding practices, as they can be non-intuitive. Websites like MDN offer valuable resources on topics such as HTML layout, vertical alignment, and more related to HTML/CSS/Javascript.

Answer №2

Solved the footer issue with a simple fix:

div.footer {
  bottom:0px;
  position:fixed;
  text-align:center;
}

But, we still need to address the primary inquiry: Strategies for Troubleshooting!

Answer №3

One amazing tool that I swear by is Firebug - it definitely outshines Chrome's tools. By inspecting an element, you can easily visualize the style hierarchy and identify any overridden styles (which are shown with a strikethrough).

Without a doubt, this is the go-to solution for understanding what's going on.

It seems like there might be z-index conflicts and text-shadow causing trouble. Try eliminating the z-index:-1 property and the text-shadow, and watch how the background starts behaving properly.
