不算。html是一种用来告知浏览器如何组织页面的标记语言,而CSS是一种用来表现HTML或XML等文件样式的样式设计语言;html和css不具备很强的逻辑性和流程控制功能,缺乏灵活性,且html和css不能按照人类的设计对一件工作进行重复的循环,直至得到让人类满意的答案。

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!

HTML5中画布标签是“<canvas>”。canvas标签用于图形的绘制,它只是一个矩形的图形容器,绘制图形必须通过脚本(通常是JavaScript)来完成;开发者可利用多种js方法来在canvas中绘制路径、盒、圆、字符以及添加图像等。

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。

3种取消方法:1、给td元素添加“border:none”无边框样式即可,语法“td{border:none}”。2、给td元素添加“border:0”样式,语法“td{border:0;}”,将td边框的宽度设置为0即可。3、给td元素添加“border:transparent”样式,语法“td{border:transparent;}”,将td边框的颜色设置为透明即可。
