aligning burger menu to right side of screen - html

Question

I have an animated burger menu that is on the left of the screen. When you click on the burger the menu expands to the right. However I want the menu to be on the right hand side. When I use float right the menu moves to the top right however it is still expanding to the right so it moves off the screen, is there any way I could flip the menu so it is expanding to the left. If anyone doesn't know what I am talking about this is the code I am using https://codepen.io/woodwoerk/pen/BoEGYZ
.menu {
margin: 0 20px 0 0;
padding-left: 1.25em;
cursor: pointer;
position: relative;
width: 30px;
height: 50px;
text-align: right;
float: right;
}
expand {
box-shadow: rgba(0, 0, 0, 0.1) -2.5px 5px 7.5px, rgba(0, 0, 0, 0.1) 2.5px 5px 7.5px;
width: 200px;
height: 50px;
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
}
.menu-top-expand {
top: 50px;
background: #FFF8E1;
-webkit-transition: all 0.5s 0.2s, left 0.1s;
transition: all 0.5s 0.2s, left 0.1s;
}
.menu-middle-expand {
top: 100px;
background: #FFECB3;
-webkit-transition: all 0.5s 0.1s, left 0.1s;
transition: all 0.5s 0.1s, left 0.1s;
}
.menu-bottom2-expand {
top: 200px;
background: #FFECB3;
-webkit-transition: all 0.5s 0.1s, left 0.1s;
transition: all 0.5s 0.1s, left 0.1s;
}
.menu-bottom-expand {
top: 150px;
height: 100px;
background: #FFE082;
-webkit-transition: all 0.5s, left 0.1s;
transition: all 0.5s, left 0.1s;
}
.menu-text-expand{
color: #000000;
opacity: 0.8;
padding: 10px;
font-size: 1.3em;
-webkit-transition: all 0.2s 0.7s, font-size 0.1s;
transition: all 0.2s 0.7s, font-size 0.1s;
}
Thanks in advance

Answer 1

So after you float: right; to .menu, on .menu-global change left to left: auto and add right: 0;

Answer 2

Same changes as #pavger, just adding : on .menu-global:hover, change left: 10px; to right 10px; to get the right effect :

.menu-global:hover {
right: 10px;
-webkit-transition: all 0.2s;
transition: all 0.2s;
}
