Mobile menu background colour

Hi there,
I have managed to change the colours in the theme except in one area - the background of the mobile phone menu. Can you advise me on where to change this? Please see my site on a cell phone. I want to change the red to blue.

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

/*change color on mobile media query*/
@media screen and (max-width: 768px){
.main-navigation .blaskan-main-menu > ul, .main-navigation .blaskan-main-menu > div {
    background: #fff;
  #primary-menu > li > a,.main-navigation ul ul li a {
    color: #000;
  .main-navigation ul ul li{

Best Regards,

Thanks! That worked great!
