I can not change the font color in mobile mode, it turns white, and if I change the CSS
to white it changes the site, it follows the menu code.
#advanced_menu_toggle, #advanced_menu_hide {
position: absolute;
border-radius: 2px;
height: 46px;
width: 46px;
line-height: 46px;
text-decoration: none;
text-align: center;
right: 0;
top: 15%;
color: #000000 !important;
margin-top: -5px;
z-index: 10000;
border-style: solid;
border-width: 1px;
font-size: 30px;
