The first one: or
These two logos are the same thing. They are mainly used for some English abbreviations. When you move the mouse up, you will find that a small prompt will appear. Prompt the full name of the abbreviation. Here is an example:
HTML
IEEE
RTFSC
Second: This logo is mainly to add double quotation marks to the quoted text. This logo seems to be very meaningless. Officially, it is for convenience, but I always feel that this logo is not as convenient as directly entering double quotes. It seems like nothing. Could it be that this logo can only be seen under Firefox, and IE does not support it. The following is an example: This is a quotation
This is a quotation
This is a quotation
The third one, is very interesting. It can put all the words in order from left to right. Reversed. For example: May I help you sir ? If this logo is added, it will look like this: May I help you sir ? What can I do for you? May I help you sir ? What can I do for you? May I help you sir ?What can I do for you?
Fourth, strikethrough your string. For example: This is a deleted text. This is a deleted textThis is a deleted text
The fifth and sixth ones, these two are subscripts and superscripts. Here are examples: This is a subscript, this is a superscript. This is a subscript, this is a superscript

本篇文章带大家了解一下HTML(超文本标记语言),介绍一下HTML的本质,HTML文档的结构、HTML文档的基本标签和图像标签、列表、表格标签、媒体元素、表单,希望对大家有所帮助!

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。
