1.众所周知,每个IE的版本都有两种模式,怪异模式(混杂模式)和标准模式。下图附上针对IE的hack。
2.另外有一种引进css的方法,也可以作为调整网站hack的方法:
除IE之外的浏览器
小雨IE6版本的IE浏览器
这里只给出了一个样式,还有很多的版本判断的,就没有全部写出来。
3.IE6中的png图片透明问题
使用DDPngMin.js插件解决;
4.双边距问题
在浮动的方向上不要有margin的这个方向的值,比如如果有float:left属性,那么就不要为该元素设置margin-left值;
5.IE6不识别max和min值,就是为元素设置的max-width、max-height和min-width、min-height在IE6中无效
解决方案:尽量少使用max和min值,甚至是不使用。
因为现在要考虑兼容iE6的网站一般都是很大众的网站,比如淘宝、京东这些尽量满足所有人的上网需求的网站,很少需要设置最小、最大值的场景。
6.清除浮动
起因:一般是盒子里面的元素使用了float属性,导致父级元素对象盒子不能被撑开,这样css的浮动就产生了。
简单来说,就是因为盒子里面的元素使用了float:left或float:right或两者都使用了而产生浮动。
负作用(都是针对父元素的)
背景不能被显示
边框不能被撑开
margin、padding值不能被正确显示
清除浮动
a.对父元素设置高度:不推荐,很多时候高度是自适应的;
b.添加空标记,对应标记样式设置为:clear:both
这里是借用的一张网络图片。
这种方式也不推荐,因为增加了空标记,界面不整洁;
c.为父元素样式设置overflow:hidden;属性,好处简短的代码就解决了问题。个人比较倾向于这种方式。
7.字体
在样式中,为元素设置字体属性的时候,尽量不要使用中文汉字。具体在什么场景下出过问题,忘记了。
8.IE6下3px的bug
这种结构的代码,在IE6种会多出一个字来。主要原因如下:
a.和注释有关
b.注释造成文字溢出和浮动有关
c.与文字块的宽度有关,无论是绝对值还是相对值都会差3px
d.溢出文字个数=注释条数X2-1;
解决方案:
a.不放注释
b.不在浮动的区块之间放注释
c.去掉文字块的固定宽度
d.将文字块包含在一个新的div中。
其实也不能算是bug,暂且就认为是当前浏览器向标准的实现程度吧。不同的浏览器的不同版本对标准的不同实现方法及实现程度。

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
