Toggle Aside Color Change

Notice i need to change the color of the aside color menu icon to black because i change the nav color to white. I tried change the color to black and inputting code in the css overide. But something is causing it to be misaligned or off padding and acting funny like not showing when scroll down.

Code i used:
#aside-menu-toggler, #mobile-menu-toggler, #static-aside-menu-toggler {
color: #fff; (((Changed This
cursor: pointer;
display: block!important;
float: right;
font-size: 32px;
height: 44px;
line-height: 44px;
margin: 14px 0!important;
margin-top: 14px;
margin-right: 0px;
margin-bottom: 14px;
margin-left: 0px;
overflow: hidden;
overflow-x: hidden;
overflow-y: hidden;

padding-top: 0px;
padding-right: 0px;
padding-bottom: 0px;
padding-left: 0px;
position: relative;
text-align: right;

}
