How to change the size of the hamburger icon? (height and width)

Go to solution Solved by tuanphan,

I'm trying to change the overall size of the hamburger icon for mobile only. I need it smaller (width and length).

I've tried code from these forums which adjusts the width only, but this is only half of the job.

It also looks to me like it is not fully left-aligned. It is further away from the left side than the cart icon from the right side, and you can see this more when the overlay menu is opened and it is inset further to the centre than the menu items itself. Any ideas how to adjust that so it is fully on the left?

Ideal example and current website screenshots attached:

Hi @johnpaulstuthridge, give this code a try:

.burger-inner.header-menu-icon-tripleLineHamburger .top-bun {
  transform: translatey(-6px);

.burger-inner.header-menu-icon-tripleLineHamburger .bottom-bun {
  transform: translatey(6px);

.burger-inner > div {
  width: 60% !important;

You can adjust the -6px and 6px up and down, which is the space in between the lines. You'll want these to be the same number for both the negative and positive so they're evenly spaced. The 60% can be changed also, this is the width of the lines within the burger menu container.

Screenshot of how this code looks on my end:

That works amazingly well, thank you!

- It has removed the cross into a X shape, which is fine, but was that supposed to happen?

You can change above code to this

body:not(.header--menu-open) .burger-inner.header-menu-icon-tripleLineHamburger .top-bun {
    transform: translatey(-6px);

body:not(.header--menu-open) .burger-inner.header-menu-icon-tripleLineHamburger .bottom-bun {
    transform: translatey(6px);

body:not(.header--menu-open) .burger-inner>div {
    width: 50% !important;
