CSS</p><p>1、选择器</p><p>元素选择器： 通过HTML元素的标签名来选择元素</p><p>类选择器： 以<code>.</code>开头，用于选择具有特定类的元素</p><p>ID选择器： 以<code>#</code>开头，用于选择具有特定ID的元素</p><p>2、盒模型</p><p>内容(content): 实际内容所在区域</p><p>填充(padding): 内容和边框之间的空间</p><p>边框(border): 环绕在填充和外边距之间的线</p><p>外边距(margin): 元素周围的空间</p><p>3、布局方式</p><p>静态定位(static): 默认布局方式，元素按照正常的文档流进行排列</p><p>相对定位(relative): 元素相对于其正常位置进行偏移</p><p>绝对定位(absolute): 元素相对于最近的已定位祖先元素进行定位</p><p>固定定位(fixed): 元素相对于浏览器窗口进行定位</p><p>浮动定位(float): 元素脱离正常文档流并向左或向右移动</p><p>弹性盒子布局(flexbox): 提供更加有效的布局、对齐和空间分配方式</p><p>网格布局(grid): 二维布局系统，用于创建复杂的设计布局</p><p>C. JavaScript</p><p>1、变量与数据类型</p><p>基本数据类型： string, number, boolean, null, undefined</p><p>对象： 由键值对组成，可存储更复杂的数据结构</p><p>2、函数</p><p>定义函数： 使用<code>function</code>关键字声明</p><p>调用函数： 使用函数名后跟括号的方式执行</p><p>匿名函数： 没有具体名称的函数，通常用于事件处理或回调</p><p>3、事件处理</p><p>事件监听： 使用<code>addEventListener</code>方法监听特定事件</p><p>事件传播： 事件从触发元素向上冒泡至根节点的过程</p><p>事件捕获： 事件从根节点向下传递至目标元素的过程</p><p>II. Web安全</p><p>A. 跨站脚本攻击 (XSS)</p><p>描述： XSS是一种常见的攻击方式，攻击者通过在网页中注入恶意脚本，当其他用户浏览该网页时，这些脚本会在用户的浏览器上执行。</p><p>防护措施： 对用户输入进行验证和清理，使用内容安全策略（CSP）限制资源的加载，以及使用HTTP头部的<code>XContentTypeOptions</code>和<code>XXSSProtection</code>来防止攻击。</p><p>B. SQL注入</p><p>描述： SQL注入是攻击者通过在应用程序的查询字符串中插入恶意SQL代码，以此来操控数据库，获取、篡改或删除数据。</p><p>防护措施： 使用预编译语句和参数化查询，限制数据库的使用权限，以及实施严格的输入验证。</p><p>C. HTTPS与SSL/TLS</p><p>描述： HTTPS是在HTTP协议上增加SSL/TLS加密的安全协议，它为数据传输提供了加密保护，确保数据在传输过程中的安全性。</p><p>应用： 网站应当使用HTTPS来保护用户数据的隐私和完整性，特别是在处理敏感信息如登录凭据、支付信息等时。</p><p>D. 认证与授权机制</p><p>描述： 认证是确认用户身份的过程，而授权是授予用户访问资源的能力，这两者是网络安全的关键组成部分。</p><p>实践案例： 使用OAuth、OpenID Connect等开放标准进行认证，以及使用JSON Web Tokens (JWT)来管理用户的会话和授权信息，Google和Facebook的API就广泛使用了OAuth 2.0来进行用户认证。</p><p>III. Web性能优化</p><p>A. 网络请求优化</p><p>减少HTTP请求： 合并CSS和JavaScript文件，使用图片精灵和图标字体来减少请求次数。</p><p>使用CDN: 利用地理分布式的内容分发网络（CDN）来加速静态资源的加载速度。</p><p>压缩资源： 启用服务器端的GZIP或Brotli压缩来减小传输文件的大小。</p><p>B. 资源加载策略</p><p>异步加载： 使用<code>async</code>和<code>defer</code>属性来控制脚本的加载和执行时机。</p><p>按需加载： 实现代码拆分，只在需要时加载特定的模块或组件。</p><p>预加载： 使用<code><link rel="preload"></code>来提前加载关键资源，加快页面渲染速度。</p><p>C. 缓存策略</p><p>HTTP缓存： 设置合适的<code>CacheControl</code>和<code>Expires</code>头部来指示浏览器缓存静态资源。</p><p>Service Workers: 使用Service Workers来控制页面和静态资源的缓存，即使在离线状态下也能提供服务。</p><p>应用案例： Amazon的电子商务平台通过优化图片大小和格式，以及实施智能的缓存策略，显著提高了页面加载速度和用户体验。</p> <br> 本文名称：web <br> 文章网址：<a href="http://www.jxjierui.cn/article/ccoccgp.html">http://www.jxjierui.cn/article/ccoccgp.html</a> </div> <div
