Three lines menu on mobile

Hi dear, is possible move three lines menu mobile in left down of top photo in my site: www.residencealparadiso.it
Is possible add a background to this three lines, because this is not visible.

Thanks

You can add this code to your css/custom.css

.uk-navbar-toggle {
color: #222222;
background: #f00;
}

Hi dear, I add your code to css file, but it is a bad work (01.jpg).
I want a result as 02.jpg.

Thank you

Hello, then use this code

.uk-navbar-toggle::after {
background: #f00;
padding: 10px;
}
