HTML Guide for background

There’s an invalid value for the background property in your CSS. The W3C HTML Validator has attempted to match the value to a background color, without success.

Here’s how to resolve this issue:

1. Identify the Correct CSS Configuration: The background property in CSS can take various forms, such as a color, an image, or a combination of background components. Ensure you provide a valid value.

2. Correct the Value: If you meant to set a background color, use a valid color format (e.g., hexadecimal, RGB, RGBA, named color, etc.).

Valid CSS Examples:

• Using a named color:

  .example {
    background: blue;
  }

• Using a hexadecimal color:

  .example {
    background: #00ff00;
  }

• Using an RGB color:

  .example {
    background: rgb(255, 0, 0);
  }

• Using an RGBA color (with transparency):

  .example {
    background: rgba(255, 0, 0, 0.5);
  }

• Setting an image as background:

  .example {
    background: url('image.jpg');
  }

• Combining multiple background properties:

  .example {
    background: url('image.jpg') no-repeat center/cover;
  }
