Brief explanation: A language that marks certain words in ordinary documents. Its purpose is to use tags to achieve the desired display effect of the document.
HTML is a descriptive language under the definition of SGML, or it can be said that HTML is an application of SGML. HTML is not a programming language, such as C++ and Java, it is just a markup language. Basically, you only need to understand the various tags Once you have learned how to use HTML, the format of HTML is very simple. It is just composed of text and markup. In terms of editing, any text editor will do, as long as the file can be saved in ASCII plain text format. Of course, use a professional Web page editing software is preferred.
■ Reading instructions:
This article [HTML Analysis] focuses on the introduction of tags. Considering the ease of understanding and the length of each section, I do not classify HTML according to W3C. This can make it easier for you to choose the tags you are interested in. Among them, only [File Mark] is required to read, and the rest can be selected at will. This article will not mention any web page editing software. As long as you master HTML, any web page editing tool can be turned into a powerful tool.
■ Tag writing method:
Any tag should be surrounded by "", such as
There should be no blank characters between the tag name and the less than sign.
Some tags require parameters, some do not. For example, Hello
parameters can only be added to the start tag.
Add the symbol "/" before the tag name of the start tag to indicate the end tag. For example,
mark letters can be uppercase or lowercase.
■ Containment mark and empty mark:
Marks are divided into containment mark and empty mark according to type
Containment mark
As the name suggests, it surrounds the text with a start mark and an end mark to achieve the expected display effect.
For example, HTML Source: Creation of Webpage is my favorite.
is displayed as: Creation of Webpage is my favorite.
where is called the containment mark.
It marks the text Creation of webpage with a start tag and an end tag, making it appear in bold. If either of them is missing, an error will occur.
Empty tag
means that the tag appears alone, with only a start tag and no end tag.
For example, HTML Source:
I love Creation of Webpage.
It's a wonderful place.
is displayed as:
I love Creation of Webpage.
It's a wonderful place.
The line break tag
is an empty tag.
Its function is to display everything after the tag on the next line. It can be seen that the terminal tag is meaningless for it, but some people will add the terminal tag to the empty tag. This is just for the convenience of memory and has no effect on HTML. Influence.

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。
