Remove page itself breadcrumb in mobile views?

Problem I see here is to know if it is a mobile view..
which is not handled by PHP but you could do that in the CSS of your theme

@media (max-width: 599px) {
// remove the last child
ol.breadcrumb > li:last-child {
    display: none;
}
// remove the > on the child before
ol.breadcrumb > li:nth-last-child(2):after {
    display: none;
}
}

your question was almost 5 years ago.. so I think it won't help you but maybe sombody thats googleling for a solution

we could maybe provide different CSS libraries for common use cases so leaving the Feature request open.

First question would be what use cases to cover

@spuky is totally right: This can't be fixed in PHP.

I would leave representational subtleties to the themers. Maintaining opinionated CSS should be out of scope for Easy Breadcrumb.

@leymannx thanks for preventing feature creep ;-)
