Question

在以下可运行的代码片段中，我使用导航栏设置了基本的布尔玛布局。导航栏很早就打破了汉堡包，因为我拥有的链接数量/大小。

我该如何仅在较小的屏幕上进行此中断？例如只能在手机上使用汉堡包。

(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');
  });
})();

您可以将$navbar-breakpoint变量设置为平板电脑。默认情况下，导航栏断点设置为桌面。

在您的main.scss中，更新布尔玛的$navbar-breakpoint变量。

// 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";

在导入_all.sass实用程序后，我将$navbar-breakpoint变量设置为$tablet的值。您需要这样做，因为必须首先设置$tablet变量。

此后，您需要设置$navbar-breakpoint变量，然后再导入导航栏组件，否则将使用默认桌面值。
