Safari - Change CSS for 1 site?

[dmmcintyre3]

I have seen the thing to use the CSS file for the whole web but I need one that changes the CSS for 1 site. (MacRumors Forums)

Is there an way to use a custom CSS file for 1 site in safari like onmiweb does?

You can always make the CSS selector specific enough that it's very unlikely to have an effect on other pages. Example for the breadcrumbs,

table.tborder span.navbar a {
 /* custom style here */
}
