Is it possible to replace a css rule with a different one?

Seeking help with CSS.

I am currently dealing with older code that has its own set of css rules linked to a 'css manager'. Now, I want to integrate jQuery UI for its appealing dialogues and features.

My inquiry is as follows: There is a css rule like...

#menu-bar{something}

Whereas jQuery UI uses rules such as:

.ui-dialog-titlebar{something2}

Is it possible (without altering jQueryUI stylesheets) to achieve something similar to:

.ui-dialog-titlebar = #menu-bar?

Essentially overwriting .ui-dialog-titlebar with {something} from #menu-bar?

Thank you in advance.

Note: I am unable to simply use

.ui-dialog-titlebar {something}

since {something} varies depending on the 'style manager' being utilized.

Answer №1

It is not possible for a CSS rule to directly inherit from another in CSS 2 or CSS 3. However, you can achieve similar effects by adding multiple CSS classes to elements. In the case mentioned, you can assign an ID to the dialog element like this:

<div id="menu-bar" title="dialog">...</div>

You can also do this programmatically with JavaScript:

$('.dialog').dialog(...).attr('id', 'menu-bar');

Keep in mind that using #menu-bar as a class instead of an ID would be more appropriate if you want multiple elements to share the same style.
