Bulma - Show Uncollapsed Navbar on Tablet

问题

In the following runnable code snippet I have setup a basic Bulma layout with a navbar. The navbar is breaking to hamburger very early for the amount/size of links I have.

How can I make this break on smaller screens only? e.g. Hamburger only on phones.

(function() {
  let burger = document.querySelector('.burger');
  let nav = document.querySelector('#' + burger.dataset.target);

  burger.addEventListener('click', function() {
    burger.classList.toggle('is-active');
    nav.classList.toggle('is-active');
  });
})();

You can set $navbar-breakpoint variable to tablet. By default navbar breakpoint is set to desktop.

In your main.scss, update Bulma's $navbar-breakpoint variable.

// Import only what you need from Bulma
@import "../node_modules/bulma/sass/utilities/_all.sass";
@import "../node_modules/bulma/sass/base/_all.sass";
@import "../node_modules/bulma/sass/elements/button.sass";
@import "../node_modules/bulma/sass/elements/container.sass";
@import "../node_modules/bulma/sass/elements/form.sass";
@import "../node_modules/bulma/sass/elements/title.sass";

$navbar-breakpoint: $tablet;

@import "../node_modules/bulma/sass/components/navbar.sass";
@import "../node_modules/bulma/sass/layout/hero.sass";
@import "../node_modules/bulma/sass/layout/section.sass";
@import "../node_modules/bulma/sass/grid/columns.sass";

I'm setting $navbar-breakpoint variable to the value of $tablet after importing _all.sass utilities. You need to do that because $tablet variable has to get set first.

After that you need to set$navbar-breakpoint variable before importing navbar component, otherwise default desktop value will be used.
