Warning: CSS Validation Notice - Identical color and background-color used in two different contexts

I have been receiving numerous warnings similar to the ones mentioned below during a CSS validation check via 

> 513       Similar color usage for both text and background in multiple areas such as #blue_module and #red_module_top, .content ul li and #red_module_top, #footer_container and #red_module_top, ul.tabs li a.active and #red_module_top, #content_960 and #red_module_top, #content_main and #red_module_top, .content and #red_module_top, #league_module select option and #red_module_top, #red_module and #red_module_top

Any suggestions on how to rectify this issue?

Answer №1

The main point being made is that having the same background color and foreground color in certain contexts can cause visibility issues. An example from your CSS is provided below:

#blue_module {
  background: url(http://www.example.com/images/blue_background.jpg) no-repeat;
  color: #000;
}

In this example, the foreground color is set to black with color: #000, but the background color is not defined. If the background image fails to load, the background will default to white (as assumed by the validator), resulting in invisible text.

To resolve this issue, you simply need to specify a color for the background. For instance:

background: #00ff00 url(http://www.example.com/images/blue_background.jpg) no-repeat;

By adding a background color, the validator can differentiate between the foreground and background colors, preventing any visibility problems.

Answer №2

The concern raised is regarding accessibility, where the color combination may hinder readability. If the text blends in with the background due to similar colors, reading becomes nearly impossible.
