Description:
In recent days, the company requires the website to implement responsive layout, so I have a relatively comprehensive understanding of responsive layout and made several examples.
Introduction to responsive layout
Reference: Wikipedia, CSS3 @media query, Bootstrap Chinese official website, despise IE, 5 of the best in 2014 Comparison of popular front-end frameworks, adaptive web design-Ruan Yifeng, responsive web design, responsive layout-Baidu Encyclopedia, responsive website design principles, the small matter of responsive layout, new principles of responsive web design, what is responsive layout design? , The difference between adaptive and responsive, Foundation Chinese website
What does responsive layout mean?
Responsive layout can present different web page layouts according to different browsing devices (PC, tablet, smartphone, etc.) while reducing zooming, panning and scrolling.
Adapt to the general trend of mobile terminals, improve user experience and reduce development costs.
Why use responsive layout?
Mainly to make web pages suitable for mobile devices. Screen resolution is the biggest compatibility issue.
Can provide different websites for different devices, that is, the same website has two pages, ordinary PC and mobile. Whether it is early development or later maintenance and revision, it is very troublesome.
Disadvantages of responsive layout?
A lot of compatible code and a lot of work
Design principles? What kind of projects is it suitable for?
Backwards compatible, mobile first.
For very complex web page layouts, it is not suitable for web page adaptive layout. One of the reasons is that the implementation cost is too high, and the second reason is that complex pages (such as the home page of Rongshang.com, the home page of China Enterprise Cluster, etc.) are not suitable. Suitable for mobile browsing.
Other responsive layout frameworks?
Prue framework is a lightweight framework from Yahoo. It is compatible with IE7 and above and has good performance. However, it has few Chinese documents, which is not conducive to team development and has no components.
Foundation by ZURB, second only to Bootstrap, heavyweight, 362K size
Bootstrap advantages ?
Low learning cost
Is currently the most popular adaptive framework
Very good performance , the most basic file size is only 149.1k
Complete Chinese documentation and a full set of video tutorials
There are many components to choose from, such as Bootstrap switch, Sco.js, Flat UI, etc., for quick and easy access Development
Compatibility
Windows platform, supports IE8. If you don’t use a framework, you need IE9 or above support, and it is compatible with IE6 through the plug-in Bsie (despise IE).

Compatibility issues (resolution breakdown-*~768 mobile phone, 768~992 tablet, 992~1200 ordinary PC, 1200~*large screen PC)

| 实例1-微博 | 无 | 无（无圆角） | 无 | 无 | 无 | 崩溃 |

| 实例3-博客 | 圆角错误 | 无圆角， 进度条无动画（无圆角，进度条无动画） | 无 | 无 | 无 | 崩溃 |
| 其它 |
Description
Chrome18 and Firefox are both old versions, and there are very few users
Does not support background attributes but can be used Position and z-index attributes can be solved
IE6 crashes can be mostly solved by using the plug-in Bsie for Bootstrap, but if support for IE6 is not required, it is not recommended and will affect performance
The pictures below show no rounded corners, normal rounded corners, and incorrect rounded corners. The rounded corners are CSS3 attributes, so there will be compatibility issues, but IE7 and above support them, which is already very good (w3school said IE9 Only the above is supported, indicating the use of css hack)
Summary: Supports mainstream browsers, and compatibility issues with older versions of browsers are not major.
Other improvements needed
Mobile version Test
Compatibility issue (resolution breakdown-
1. *~768 mobile phone, 1 column
2. 768~992 tablet , 2 columns
3. 992~1200 ordinary PC , 2 columns
4. 1200~* Large screen PC , 3 columns
)
| 分辨率dpi | ppi | 型号 | 竖 | 横 |
| 2560x1536 | 546 | MX4 pro | 1 | 1 |
| 720x1280 | 华为荣耀3c | 1 | 1 | |
| 1200x1920 | 华为 x1 7.0 | 1 | 2 | |
Since there is no tablet now, there is no way to test it. It will be completed after testing.
In addition, I don’t know why the resolution of 2560x1536 cannot display three columns but only one column. I don’t know what dpi and ppi mean. I hope anyone who knows can reply. Thanks! ^_^
