网页抽象成三部分(HTML、CSS和JavaScript)后的优点有哪些?

HTML负责页面内容和结构 CSS负责样式表现 JS负责页面动态交互 抽象成三部分优点:1.增加代码可读性 2.按需加载资源 3.便于后期维护
Sorry, something went wrong.
结构、表现、行为
有利于模块化,CSS 和 JS 可以作为单独的文件,引入到 HTML 文件中。
HTML为结构、CSS为表现、Javascript为行为。网页抽象成三部分(HTML、CSS和JavaScript)后的优点如下: 1.代码结构清晰,可读性强; 2.抽象为3部分,提高代码维护性和复用性; 3.Javascript放置在页面底部或使用defer/async属性加载,可以提高页面加载性能。其次,将CSS样式放在头部可以提高页面渲染速度。
