If you saw this article first, it is recommended that you go to the link above and read the corresponding content first, so that the context is coherent and it is easier to understand the content of this article.
The first three chapters all talk about how to implement an ordinary list. The difficulty ranges from easy to difficult, but in general, you can master it at a glance. In this chapter, we will make a graphic list.
Ordinary two-column picture (picture is a square) text list
Two-column picture and text list is very common. It is even more common in e-commerce mobile H5 terminals such as JD\TB. Here, we Let’s do the simplest one first. As shown in the figure below.
Here is a very simple two-column layout of pictures and texts. Each block contains pictures, names and Price. It is too simple to implement such a layout on the PC side. But since we are on the mobile side, the widths of different mobile phones are inconsistent. Therefore, the requirements are adaptive.
Here All pictures are of uniform specifications and are square. In actual projects, there are generally requirements for product pictures. If your product is not square, we will have relevant tutorials below.
html code
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" /> <title>list 2</title> <link rel="stylesheet" href="../style/style.css"></head><body><p class="list_2"> <ul> <li> <a href=""> <img class="goods_photo lazy" src="/static/imghwm/default1.png" data-src="../image/goods.jpg" alt="商品图片" > <h4 id="这里是商品标题">这里是商品标题1</h4> <em class="goods_price">¥4999.00</em> </a> </li> <li> <a href=""> <img class="goods_photo lazy" src="/static/imghwm/default1.png" data-src="../image/goods.jpg" alt="商品图片" > <h4 id="这里是商品标题">这里是商品标题2</h4> <em class="goods_price">¥4999.00</em> </a> </li> <li> <a href=""> <img class="goods_photo lazy" src="/static/imghwm/default1.png" data-src="../image/goods.jpg" alt="商品图片" > <h4 id="这里是商品标题">这里是商品标题3</h4> <em class="goods_price">¥4999.00</em> </a> </li> <li> <a href=""> <img class="goods_photo lazy" src="/static/imghwm/default1.png" data-src="../image/goods.jpg" alt="商品图片" > <h4 id="这里是商品标题">这里是商品标题4</h4> <em class="goods_price">¥4999.00</em> </a> </li> </ul></p></body></html>
The code is relatively long, but it can still be seen clearly at a glance. We have added different classes to different elements. The purpose of this is to make it site-wide, The basic styles using these elements can be unified and CSS code reuse can be achieved.
SASS code
.list_2 { ul { @extend .cf; // 引用清理浮动代码片,看不懂请看本人scss相关教程 li { width: 50%;float: left;padding: 1rem 0; outline: 1px solid #ddd; // 使用 outline 模拟边框 (outline不占据盒子模型) background: #fff; // 使用白色背景颜色,防止 outline 重叠造成 2px 线条 a { display: block; text-decoration: none; // 去除默认下划线 } .goods_title,.goods_price { padding: 0 1rem; // 加上左右内填充,防止文字和边框粘结 text-align: center; } .goods_photo { width: 60%;margin: .5rem auto;display: block; } } } }// 全站范围内用到的图文基本样式.goods_title,.goods_price { display: block;position: relative; @include ts(); // 引用文字描白边代码片 @include online(1.8rem); // 引用文字超出一行省略号代码片} .goods_title {color:#000;font-size: 1.2rem;} .goods_price {color:#f60;font-size: 1.5rem;font-weight: bold;}
Let me emphasize again that the CSS part of this series of tutorials uses SASS syntax. If you don’t know SASS syntax, it is recommended to spend half an hour to an hour learning SASS.
Here, we will extract some common styles throughout the site. This will facilitate code reuse.

There is no difference between HTML5 and H5, which is the abbreviation of HTML5. 1.HTML5 is the fifth version of HTML, which enhances the multimedia and interactive functions of web pages. 2.H5 is often used to refer to HTML5-based mobile web pages or applications, and is suitable for various mobile devices.

HTML5 is the latest version of the Hypertext Markup Language, standardized by W3C. HTML5 introduces new semantic tags, multimedia support and form enhancements, improving web structure, user experience and SEO effects. HTML5 introduces new semantic tags, such as, ,, etc., to make the web page structure clearer and the SEO effect better. HTML5 supports multimedia elements and no third-party plug-ins are required, improving user experience and loading speed. HTML5 enhances form functions and introduces new input types such as, etc., which improves user experience and form verification efficiency.

How to write clean and efficient HTML5 code? The answer is to avoid common mistakes by semanticizing tags, structured code, performance optimization and avoiding common mistakes. 1. Use semantic tags such as, etc. to improve code readability and SEO effect. 2. Keep the code structured and readable, using appropriate indentation and comments. 3. Optimize performance by reducing unnecessary tags, using CDN and compressing code. 4. Avoid common mistakes, such as the tag not closed, and ensure the validity of the code.

H5 improves web user experience with multimedia support, offline storage and performance optimization. 1) Multimedia support: H5 and elements simplify development and improve user experience. 2) Offline storage: WebStorage and IndexedDB allow offline use to improve the experience. 3) Performance optimization: WebWorkers and elements optimize performance to reduce bandwidth consumption.

HTML5 code consists of tags, elements and attributes: 1. The tag defines the content type and is surrounded by angle brackets, such as. 2. Elements are composed of start tags, contents and end tags, such as contents. 3. Attributes define key-value pairs in the start tag, enhance functions, such as. These are the basic units for building web structure.

HTML5 is a key technology for building modern web pages, providing many new elements and features. 1. HTML5 introduces semantic elements such as, , etc., which enhances web page structure and SEO. 2. Support multimedia elements and embed media without plug-ins. 3. Forms enhance new input types and verification properties, simplifying the verification process. 4. Offer offline and local storage functions to improve web page performance and user experience.

Best practices for H5 code include: 1. Use correct DOCTYPE declarations and character encoding; 2. Use semantic tags; 3. Reduce HTTP requests; 4. Use asynchronous loading; 5. Optimize images. These practices can improve the efficiency, maintainability and user experience of web pages.

Web standards and technologies have evolved from HTML4, CSS2 and simple JavaScript to date and have undergone significant developments. 1) HTML5 introduces APIs such as Canvas and WebStorage, which enhances the complexity and interactivity of web applications. 2) CSS3 adds animation and transition functions to make the page more effective. 3) JavaScript improves development efficiency and code readability through modern syntax of Node.js and ES6, such as arrow functions and classes. These changes have promoted the development of performance optimization and best practices of web applications.
