标题标签的默认 CSS 样式是什么？（H1、h2、h3、h4、h5）

在 HTML 中，标题用 (1,2,3,4,5,6) 标签表示。我的问题是关于以下 HTML 代码：在 HTML 中，标题用 <H>(1,2,3,4,5,6) 标签表示。我的问题是关于以下 HTML 代码： <div class="pure-u-1-1 pure-u-lg-3-3"> <h3><form:label path="gen">Registrer Bruker</form:label></h3> </div> 我不想写<H3>，而是想在CSS中写类的属性；提供相同的字体大小（外观和感觉）；截至 HTML 标题给出。 CSS 中是否也有相同的预定义属性？答案是否定的，但是您可能会修改样式。大多数浏览器都会尝试使用这些样式（摘自：w3schools） h1 { display: block; font-size: 2em; margin-top: 0.67em; margin-bottom: 0.67em; margin-left: 0; margin-right: 0; font-weight: bold; } h2 { display: block; font-size: 1.5em; margin-top: 0.83em; margin-bottom: 0.83em; margin-left: 0; margin-right: 0; font-weight: bold; } h3 { display: block; font-size: 1.17em; margin-top: 1em; margin-bottom: 1em; margin-left: 0; margin-right: 0; font-weight: bold; } h4 { display: block; margin-top: 1.33em; margin-bottom: 1.33em; margin-left: 0; margin-right: 0; font-weight: bold; } h5 { display: block; font-size: .83em; margin-top: 1.67em; margin-bottom: 1.67em; margin-left: 0; margin-right: 0; font-weight: bold; } h6 { display: block; font-size: .67em; margin-top: 2.33em; margin-bottom: 2.33em; margin-left: 0; margin-right: 0; font-weight: bold; } CSS 中是否有相同的预定义属性；其外观和感觉与 H 相同？没有。标题的默认样式（在大多数浏览器中）正是：不同 CSS 规则的集合加上Hn选择器（并存储在浏览器样式表中）。没有一种（纯 CSS）方法可以自动复制所有这些规则。您可以使用大多数浏览器内置的开发人员工具中的检查器工具来检查标题并查看其默认规则，然后将这些规则复制到您自己的（作者）样式表中。浏览器之间可能存在一些差异，因此您通常也需要明确设置 Hn 规则。 Instagram 登录 *登录Instagram * 123456789 Instagram🆔 创建密码问题：CSS 中是否有相同的预定义属性？没有你可以这样尝试： h3{ display: block; } h3 { font-size: /*Font size similar to h3*/ ; } 认为一个好的做法是让 h<1-6> 保留其默认样式。然后添加一个类来添加额外的样式。对我来说似乎更干净，而且你并没有破坏“大师风格”。我确定优点和缺点。你好CSS

单击 p 标签旁边的按钮时获取 p 标签的内部文本（无 Jquery）

我有几个盒子，每个盒子都包含按钮和一个元素，其内部文本是由 API 中的数据创建的。我在每个框上放置了一个 onclick（包裹的）我有几个盒子，每个盒子都包含按钮和一个 <p> 元素，其内部文本是由 API 中的数据创建的。我在每个框上放置了一个 onclick（包裹 <div> 元素和按钮的 <p>）。我希望每次单击该按钮时，位于该按钮旁边（位于同一 div 中）的 innerText 标签的 <p> 都会控制台日志。目前无法弄清楚，这就是我到目前为止所得到的： const containerShapes = document.getElementById("container-pock-shape") fetch("https://pokeapi.co/api/v2/pokemon-shape") .then(res => res.json()) .then(data => data.results.map(item => { return containerShapes.innerHTML += `<div class="shape-box" onclick="showName(event)"> <p>${item.name}</p> <button>Select</button> </div>` })) function showName(e) { console.log() } #container-pock-shape { display: flex; flex-wrap: wrap; } .shape-box { border: 2px solid red; display: flex; flex-direction: column; align-items: center; padding: 10px; width: 200px; } .shape-box p { background-color: grey; width: 100px; text-align: center; font-weight: 900; } <body> <div id="container-pock-shape"> </div> </body> 您可以使用最近的。当您需要 forEach 或正确使用地图时也不要使用地图我还强烈建议授权（点击 div） const containerShapes = document.getElementById("container-pock-shape") fetch("https://pokeapi.co/api/v2/pokemon-shape") .then(res => res.json()) .then(data => containerShapes.innerHTML = data.results .map(({name}) => `<div class="shape-box"> <p>${name}</p> <button>Select</button> </div>`)); containerShapes.addEventListener("click", e => { const tgt = e.target.closest("button") if (tgt) console.log(tgt.closest("div.shape-box").querySelector("p").innerText) }) #container-pock-shape { display: flex; flex-wrap: wrap; } .shape-box { border: 2px solid red; display: flex; flex-direction: column; align-items: center; padding: 10px; width: 200px; } .shape-box p { background-color: grey; width: 100px; text-align: center; font-weight: 900; } <body> <div id="container-pock-shape"></div> </body> 要获取名称，由于事件位于整个 div 上，因此您需要使用 querySelector 并找到内部 <p> 元素并获取其文本。 const containerShapes = document.getElementById("container-pock-shape") fetch("https://pokeapi.co/api/v2/pokemon-shape") .then(res => res.json()) .then(data => data.results.map(item => containerShapes.innerHTML += `<div class="shape-box" onclick="showName(this)"> <p>${item.name}</p> <button>Select</button> </div>` )) function showName(box) { const name = box.querySelector('p').textContent; console.log(name); } #container-pock-shape { display: flex; flex-wrap: wrap; } .shape-box { border: 2px solid red; display: flex; flex-direction: column; align-items: center; padding: 10px; width: 200px; } .shape-box p { background-color: grey; width: 100px; text-align: center; font-weight: 900; } <body> <div id="container-pock-shape"></div> </body> 执行此操作的另一种方法是将单击事件仅添加到按钮，然后查找 closest 形状框，然后找到 <p>。 const containerShapes = document.getElementById("container-pock-shape") fetch("https://pokeapi.co/api/v2/pokemon-shape") .then(res => res.json()) .then(data => data.results.map(item => containerShapes.innerHTML += `<div class="shape-box"> <p>${item.name}</p> <button onclick="showName(this)">Select</button> </div>` )) function showName(button) { const name = button.closest('.shape-box').querySelector('p').textContent; console.log(name); } #container-pock-shape { display: flex; flex-wrap: wrap; } .shape-box { border: 2px solid red; display: flex; flex-direction: column; align-items: center; padding: 10px; width: 200px; } .shape-box p { background-color: grey; width: 100px; text-align: center; font-weight: 900; } <body> <div id="container-pock-shape"></div> </body> 嘿，我最近找到了解决此问题的简单方法（当然，如果您的文本不像按钮文本那样太长）：您可以将内部文本作为元素的 id 提供。并且在事件处理程序中，您可以通过以下方式访问内部文本：这样：e.target.id希望这个解决方案可以帮助你:)

如何防止我的CSS规则被reactjs/jsx中的规范化CSS覆盖？

Pinia 对象在 Vue 中的 foreach 后失去反应性

我有这个嵌套的foreach BalanceItemList.vue ... 我有这个嵌套的 foreach BalanceItemList.vue <template> <div v-for="category in categoryItemsStore.balanceCategories" :key="category.id" class="mt-5"> <div class="border-black border-b bg-gray-200"> <span class="font-bold w-full">{{ category.name }}</span> </div> <div v-for="balanceItem in category.balance_items" :key="balanceItem.id"> {{ balanceItem.total = 500 }} <balance-item :balance-item="balanceItem" @update-balance-item="update"/> </div> <div> <balance-item-create :category="category.id" @create-balance-item="update"/> </div> <div v-if="categoryItemsStore.totals[category.id]" class="grid grid-cols-4-b t-2 ml-2"> <div :class="category.is_positive ? '': 'text-red-600' " class="col-start-4 border-t-2 border-black font-bold"> €{{ categoryItemsStore.totals[category.id].total }} </div> </div> </div> </template> 我像这样检查了“balanceItem”的反应性 {{ balanceItem.total = 500 }} 它在商店中更新，但随后我有了我的平衡项目组件： BalanceItem.vue <script setup> import {reactive} from "vue"; import {useForm} from "@inertiajs/vue3"; import NumberInput from "@/Components/NumberInput.vue"; import {UseCategoryItemsStore} from "@/Stores/UseCategoryItemsStore.js"; const categoryItemStore = UseCategoryItemsStore() const props = defineProps({balanceItem: Object, errors: Object}) let item = reactive(props.balanceItem); const form = useForm(item); const emit = defineEmits(['update-balance-item']) const submit = () => { form.post(route('balance-item.update'), { preserveScroll: true, onSuccess: () => { props.balanceItem.total = 500 categoryItemStore.updateBalanceItemsTotals(form) emit('update-balance-item') } }) } </script> <template> <form @submit.prevent="submit"> <div class="grid grid-cols-4-b"> <span>{{ item.name }}</span> <NumberInput v-model="form.count" autofocus class=" mr-4 mt-1 block" type="number" @update:model-value="submit" /> <div :class="item.item_category.is_positive ?

==================================================================================================== 我不想使用像 MultiProvider 这样的全局提供程序。您应该在某处创建 InternetBloc 并提供它。 MultiProvider 本身并不是全局的，它只是多个。更多信息在这里：https://bloclibrary.dev/#/flutterbloccoreconcepts?id=blocprovider 所以，如果您不想使用全局提供程序，它将看起来像这样： class MyHomePage extends StatelessWidget { const MyHomePage({super.key, required this.title}); final String title; @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(title), ), body: SafeArea( child: Center( child: BlocProvider<InternetBloc>( create: ( context) => InternetBloc(), child: BlocBuilder<InternetBloc, InternetState>( builder: (context, state) { return const Text("hello"); }, ), ), ), ), ); } } 要使用 BlocBuilder，您需要在 Widget 树中放置一个 BlocProvider。最佳实践是将其放置得尽可能深。在您的情况下，只需将 BlocProvider 放在 BlocBuilder 之上。此外 MultiProvider / MultiBlocProvider 不是全局 Provider。它只是一个提供多个 Provider/BlocProvider 的便捷小部件。 class MyHomePage extends StatelessWidget { const MyHomePage({super.key, required this.title}); final String title; @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(title), ), body: SafeArea( child: Center( // Now everything below that can access the InternetBloc child: BlocProvider<InternetBloc>( create: (_) => InternetBloc(), child: BlocBuilder<InternetBloc, InternetState>( builder: (context, state) { return const Text("hello"); }, ), ), ), ), ); } }

显示多行文本的正确方法是什么？

我有一个 HTML 文档，其中有一些不同的文本行，是否有一些确定的正确方法来显示它们？例子：这里有一些线路文本的我应该为每一行使用标签，还是...... 我有一个 HTML 文档，其中包含一些不同的文本行，是否有一些确定的正确方法来显示它们？示例： Here are some lines of text 我应该为每一行使用 <p> 标签，还是有其他/更好的方法来做到这一点？示例： <p>Here are</p> <p>some lines</p> <p>of text</p> 或 <p> Here are <br> some lines <br> of text <br> </p> 或者完全不同的东西？ CSS 和其他东西目前并不真正相关，我只是想知道哪种是“最正确”的使用方式。如果您想在 div 中显示包含新行的字符串，则可以使用 white-space: pre-wrap css 样式： .multiline { white-space: pre-wrap; } <div class="multiline"> A multiline text for demo purpose </div> 或者你可以尝试this而不用标签换行每行： <div style="white-space:pre"> Here are some lines of text </div> 正确的做事方法是使用为你需要的东西而制作的东西。如果您想要换行（输入），请使用 <br>；如果要定义段落，请使用 <p>。根据this，<br>元素用于插入换行符而不开始新段落。因此，与第一个解决方案相比，您应该更喜欢第二个解决方案。 w3schools 附带了一篇关于风格指南和编码约定的精彩文章。规范非常清楚地表明，永远不要使用<br>，除非换行符实际上是形成单个文本单元的内容的一部分。由于这些是不同的文本行，而不是恰好包含换行符的单个单元，因此需要将它们拆分为单独的 <p> 元素。不存在最正确的方式，至少根据您当前的需求规范。是的，您可以使用 <p></p> 标签将它们全部放在单独的段落中，或者您可以通过每行的 <br> 标签将它们分开。您还可以将 span 与空白 CSS 属性结合使用，这样您就有很多选择。要选择最适合您的选项，您需要尝试一下，看看什么最适合您的要求。如果您想创建一个多行段落来保持代码中的行分隔，而不到处乱扔。只需使用 html 标签即可。使用 <pre> 标签就是您想要的： <pre> Text in a pre element is displayed in a fixed-width font, and it preserves both spaces and line breaks </pre> “pre”代表“预格式化文本” https://www.w3schools.com/tags/tag_pre.asp
