所以，我一直在嘗試制作一個 jQuery 函式，一旦點擊它就會改變段落的字體樣式。
這是我嘗試過的代碼：
$(document).ready(function() {
$("#story-p").click(function() {
$(this).css({
"font-family": "Arial, Helvetica, sans-serif",
"font-size": "200%",
});
});
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<body>
<img class="background" src="restaurant.jpg" style="display: none" />
<h1 class="heading">Fuego</h1>
<div class="container">
<h1 class="story">Our Story</h1>
<p class="story-p">
Test
</p>
</body>我不明白為什么它不起作用？
我錯過了什么嗎？
非常感謝

它不起作用，因為您選擇附加單擊事件使用$('#story-p')，這意味著它的目標是一個元素，id=story-p但您的段落沒有 id 而是它的類為story-p.
因此，如下所示更改您的選擇器，它將開始作業。
$(document).ready(function() {
$(".story-p").click(function() {
$(this).css({
"font-family": "Arial, Helvetica, sans-serif",
"font-size": "200%",
});
});
});<body>
<img class="background" src="restaurant.jpg" style="display: none" />
<h1 class="heading">Fuego</h1>
<div class="container">
<h1 class="story">Our Story</h1>
<p class="story-p">

// 首先，對于現代 javascript，您實際上并不需要使用 jquery。而且您為段落 elemnet 使用了錯誤的選擇器。
<script>
$(document).ready(function(){
$(".story-p").click(function(){
$(this).css("font-family", "Arial, Helvetica, sans-serif");});
});
