前面的话
前面已经介绍过单列定宽单列自适应的两列布局,而两列自适应布局是指一列由内容撑开,另一列撑满剩余宽度的布局方式。本文将从float、table和flex来介绍两列自适应布局的3种思路。
思路一: float
在单列定宽单列自适应的两列布局中,经常用float和负margin配合实现布局效果。但由于margin取值只能是固定值,所以在两列都是自适应的布局中就不再适用。而float和overflow配合可实现两列自适应效果。使用overflow属性来触发bfc,来阻止浮动造成的文字环绕效果。由于设置overflow:hidden并不会触发IE6-浏览器的haslayout属性,所以需要设置zoom:1来兼容IE6-浏览器
<style>p{margin: 0;}.parent{overflow: hidden;zoom: 1;}.left{float: left;margin-right: 20px;} .right{overflow: hidden;zoom: 1;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
思路二: table
若table元素不设置table-layout:fixed,则宽度由内容撑开。在某个table-cell元素的外层嵌套一层div,并设置足够小的宽度如width:0.1%
<style>p{margin: 0;}.parent{display:table;width:100%;}.leftWrap{display:table-cell;width:0.1%;}.left{margin-right: 20px;} .right{display:table-cell;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="leftWrap" style="background-color: pink;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
思路三: flex
flex弹性盒模型是非常强大的布局方式。基本上,一般的布局方式都可以实现
[注意]IE9-不支持
<style>p{margin: 0;}.parent{display:flex;} .right{margin-left:20px; flex:1;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>

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.

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.
