Menu Colors

Hi everyone,

I know this is kind of an easy questions, but for some reasons, I just can’t figure it out. Not sure though if the problem is with the theme. I’m currently using a Bridge Child Theme, updated it in custom.css but nothing happened. Menu colors is still white though I changed it to blue. I used this code below. Would really appreciate your help.

nav.main_menu > ul > li > a {
color: #100033;
font-family: ‘Raleway’, sans-serif;
font-size: 13px;
font-style: normal;
font-weight: 700;
letter-spacing: 0px;
text-transform: uppercase;
}
