Hey guys,

I'm looking to make the Shopping cart icon that's displayed on the navigation bar sticky.

Any suggestions?

Thank you

It looks like you solved with this? (However the code make header overlap main content)

.Header.Header--top {
    position: fixed;
    top: 0px;
    z-index: 1000;
    width: 100%;
    box-shadow: 0px 2px 3px rgb(0 0 0 / 10%);
}
