index.html代表网页的首页文件,是网站的默认页面。当用户访问一个网站时,通常会首先加载index.html页面。HTML(HypertextMarkupLanguage)是一种用于创建网页的标记语言,index.html也是一种HTML文件。它包含网页的结构和内容,以及用于格式化和布局的标签和元素。下面是一个示例的index.html代码:<

总结了一些web前端面试(笔试)题分享给大家,本篇文章就先给大家分享HTML部分的笔试题(附答案),大家可以自己做做,看看能答对几个!

在html中,document是文档对象的意思,代表浏览器窗口的文档;document对象是window对象的子对象,所以可通过“window.document”属性对其进行访问,每个载入浏览器的HTML文档都会成为Document对象。

html5废弃了dir列表标签。dir标签被用来定义目录列表,一般和li标签配合使用,在dir标签对中通过li标签来设置列表项,语法“<dir><li>列表项值</li>...</dir>”。HTML5已经不支持dir,可使用ul标签取代。

MySQL中的index是索引的意思,是一种数据结构,用于加快数据库表的查询速度,索引可以类比于书籍的目录,存储了表中特定列的值和对应的行位置,使得数据库能够更快地定位和访问数据。索引的作用是提高查询效率,在没有索引的情况下,数据库需要逐行扫描整个表来找到匹配的数据,这种方式在大型表中会非常耗时,而有了索引后,数据库可以根据索引的顺序快速定位到所需的数据行,大大提高了查询速度。
