What are common pitfalls when using images instead of color codes in PHP for background display?

Using images instead of color codes for background display in PHP can lead to slower loading times and increased bandwidth usage. To solve this issue, consider using CSS background-color properties instead of images whenever possible to improve performance.

<!DOCTYPE html>
<html>
<head>
<style>
  body {
    background-color: #f0f0f0; /* Use color code instead of image */
  }
</style>
</head>
<body>

<h1>Hello World!</h1>
<p>This is a simple example of using color codes for background display.</p>

</body>
