wordpress theming - How to add custom css that my code is not working?

Question

I am trying to code in the WordPress custom CSS plugin but I can't do it. This is the image.enter image description here

If you look into the image you will see a nav where some plus icon is there but I am trying to set on the left side of the navbar. I used this code to change the side.

#nm-mobile-menu .menu li .nm-menu-toggle {
    position: absolute;
    top: 6px;
    left: 0;
    display: none;
    height: 28px;
    font-family: 'nm-font';
    font-size: 11px;
    line-height: 28px;
    font-weight: normal;
    color: #282828;
    padding-left: 10px;
}
