Is there a way to change the relative position value of an element by browser?

Question

I have a quick question, I'm wondering if it is possible to change the position value of a certain element in ONLY FireFox by adjusting the main CSS file?

Answer 1

You can use @-moz-document to only target Firefox. Add it to your main.css to overwrite the existing rules.

@-moz-document url-prefix() {
    element {
        position: relative;
    }
}

See this question.
