what controls a CSS transform's horizontal movement? - css

Question

I found a pure CSS mobile burger menu solution on codepen, and I altered the code with
transform: translate(-200%, 0);
/* Mobile Menu */
#menuToggle {
display: block;
position: relative;
top: 10px;
left: 50%;
z-index: 1;
-webkit-user-select: none;
user-select: none;
}
#menuToggle a {
text-decoration: none;
color: #232323;
transition: color 0.3s ease;
}
#menuToggle a:hover {color: tomato;}
#menuToggle input {
display: block;
width: 40px;
height: 32px;
position: absolute;
top: -7px;
left: -5px;
cursor: pointer;
opacity: 0; /* hide this */
z-index: 2; /* and place it over the hamburger */
-webkit-touch-callout: none;
}
#menuToggle span {
display: block;
width: 33px;
height: 4px;
margin-bottom: 5px;
position: relative;
background: #cdcdcd;
border-radius: 3px;
z-index: 1;
transform-origin: 4px 0px;
transition: transform 0.5s cubic-bezier(0.77, 0.2, 0.05, 1.0), background 0.5s cubic-bezier(0.77, 0.2, 0.05, 1.0), opacity 0.55s ease;
}
#menuToggle span:first-child {transform-origin: 0% 0%;}
#menuToggle span:nth-last-child(2) {transform-origin: 0% 100%;}
#menuToggle input:checked ~ span {
opacity: 1;
transform: rotate(45deg) translate(-2px, -1px);
background: #232323;
}
#menuToggle input:checked ~ span:nth-last-child(3) {
opacity: 0;
transform: rotate(0deg) scale(0.2, 0.2);
}
#menuToggle input:checked ~ span:nth-last-child(2) {
transform: rotate(-45deg) translate(0, -1px);
}
#mobile-menu {
position: absolute;
width: 300px;
margin: -100px 0 0 -50px;
padding: 50px;
padding-top: 125px;
background: #ededed;
list-style-type: none;
-webkit-font-smoothing: antialiased;
transform-origin: 0% 0%;
transform: translate(-200%, 0);
transition: transform 0.5s cubic-bezier(0.77, 0.2, 0.05, 1.0);
}
#mobile-menu li {
padding: 10px 0;
font-size: 22px;
}
#menuToggle input:checked ~ ul {transform: none;}
/* End Mobile Menu */

On the live site, I see the following when clicking on the burger icon:
What is going wrong with the transform: translate(-200%, 0); transform?
Help appreciated.

your toggle-menu is hide, first of all you need to display it and thien try this:
#menuToggle {
display: block;
position: absolute;
top: 50px;
left: 50px;
z-index: 1;
-webkit-user-select: none;
user-select: none;
}
#mobile-menu {
position: absolute;
width: 300px;
margin: -100px 0 0 -100px;
padding: 50px;
padding-top: 50px;
padding-top: 125px;
background: #ededed;
list-style-type: none;
-webkit-font-smoothing: antialiased;
transform-origin: 0% 0%;
transform: translate(-200%, 0);
transition: transform 0.5s cubic-bezier(0.77, 0.2, 0.05, 1.0);
}
