Why Does Changing Text Color in Disabled Textboxes Work Differently in IE6/7 and Firefox?

IE Disabled Textbox Font Color Modification

In Firefox, modifying the text color of a disabled textbox is simple through the use of a CSS class. However, this technique falls short in Internet Explorer versions 6 and 7.

The concern is that applying a class with the intention of changing the disabled textbox's text color to red, results in gray text in IE, while Firefox displays the desired red. Other browsers show similar variations in behavior.

This discrepancy arises from the differing levels of control that operating systems exert over form field rendering. Some aspects follow CSS rules more closely than others. Scripting methods are not applicable in this instance.

The recommended workaround is to employ the 'readonly' attribute instead of 'disabled' and utilize CSS (for example, based on 'class="disabled"') to recreate the disabled appearance. 'readonly' input elements are not rendered as OS-level disabled widgets, allowing for greater customization options.
