Understanding the dissimilarities between the input:disabled and input[disabled] CSS selectors

Is there a distinction between using the :disabled CSS pseudo-class selector and the [disabled] CSS attribute selector when applying styles to a disabled HTML input element, or are they essentially identical? Perhaps in terms of browser support or other factors?

Answer №1

:disabled was first added in the CSS3 specification, while [disabled] has been around since CSS2.

Personally, I find :disabled to be more preferable compared to [disabled]. For a detailed discussion on this topic, check out this question on Stack Overflow: Should I use CSS :disabled pseudo-class or [disabled] attribute selector or is it a matter of opinion?

Answer №2

The :disabled selector is compatible with browsers that support CSS3, while the [disabled] selector works with browsers that support CSS2 and later versions.

Both selectors have similar browser support, with the main difference being compatibility with older versions of Internet Explorer (IE7 backward vs IE9 backward).

Additionally, the [disabled] selector is supported by native browsers in previous mobile operating system versions.
