How to always show responsive menu in Genesis Sample

In Genesis Facebook group a user asks:

Hi Everyone,

Using Genesis Sample child theme and I want to always display the mobile navigational menu – even on desktop. I’m having a hard time finding a tutorial for that. Thanks!

And the answer is to simply remove the relevant CSS in the 960px min-width media query.

In style.css scroll down to 960px min-width media query.

Delete the following (lines 1449 to 1530):

/* Genesis Menu
--------------------------------------------- */

.genesis-nav-menu .menu-item {
    display: inline-block;
}

.genesis-nav-menu .menu-item:focus,
.genesis-nav-menu .menu-item:hover {
    position: relative;
}

.genesis-nav-menu > .menu-bold > a {
    font-weight: 700;
}

.genesis-nav-menu > .menu-highlight > a {
    background-color: #333;
    border-radius: 3px;
    color: #fff;
    font-weight: 600;
    margin-left: 15px;
    padding-left: 20px;
    padding-right: 20px;
}

.genesis-nav-menu > .menu-highlight > a:hover,
.genesis-nav-menu > .menu-highlight > a:focus {
    background-color: #0073e5;
}

.genesis-responsive-menu .genesis-nav-menu .sub-menu,
.genesis-responsive-menu .genesis-nav-menu .sub-menu a {
    width: 180px;
}

.genesis-nav-menu .sub-menu {
    border-top: 1px solid #eee;
    opacity: 0;
    padding-left: 0;
    position: absolute;
    transition: opacity .4s ease-in-out;
}

.genesis-nav-menu .sub-menu a {
    border: 1px solid #eee;
    border-top: 0;
    padding-bottom: 15px;
    padding-top: 15px;
}

.genesis-nav-menu .sub-menu .sub-menu {
    margin: -46px 0 0 179px;
}

/* Responsive Menu
--------------------------------------------- */

.genesis-responsive-menu {
    display: block;
    padding-top: 15px;
}

.menu-toggle,
.sub-menu-toggle {
    display: none;
    visibility: hidden;
}

/* Header Menu
--------------------------------------------- */

.nav-primary {
    clear: none;
    float: right;
    width: auto;
}

.nav-primary .genesis-nav-menu a {
    padding-left: 15px;
    padding-right: 15px;
}
