* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

--description--

可以通過 jQuery 改變元素開始和結束標籤之間的文本。 甚至改變 HTML 標籤。

jQuery 有一個 .html() 函數,能用其在標籤裏添加 HTML 標籤和文本, 函數提供的內容將完全替換之前標籤的內容。

下面是重寫並強調標題文本的代碼:

$("h3").html("<em>jQuery Playground</em>");

jQuery 還有一個類似的函數 .text(),可以在不添加標籤的前提下改變標籤內的文本。 換句話說,這個函數不會評估傳遞給它的任何 HTML 標記,而是將其視爲要替換現有內容的文本。

給 id 爲 target4 的按鈕的文本添加強調效果。

查看這篇關於 <em> 的文章來了解更多 <i><em> 的區別和用法。

注意,<i> 標籤雖然傳統上用來強調文本,但此後常用作圖標的標籤。 <em> 標籤作爲強調標籤現在已被廣泛接受。 可以使用任意一種完成這個挑戰。

--hints--

應該通過添加 HTML 標籤強調 target4 按鈕中的文本。

assert.isTrue(
  /<em>|<i>\s*#target4\s*<\/em>|<\/i>/gi.test($('#target4').html())
);

文本應該保持不變。

assert($('#target4') && $('#target4').text().trim() === '#target4');

不應該改變其它任何文本內容。

assert.isFalse(/<em>|<i>/gi.test($('h3').html()));

應該使用 .html() 方法而不是 .text() 方法。

assert(code.match(/\.html\(/g));

應該使用 jQuery 選取 button id="target4"

assert(code.match(/\$\(\s*?(\"|\')#target4(\"|\')\s*?\)\.html\(/));
