How can I define fieldset border color?

Question

I want to set border color of field set. I am using class but this is not working properly because i want to remove fieldset default border color. so how can I use fieldset

Answer 1

I added it for all fieldsets with

fieldset {
        border: 1px solid lightgray;
    }

I didnt work if I set it separately using for example

border-color : red

. Then a black line was drawn next to the red line.
