I recently made a Web website. I always thought bootstrap was very good. This time I used bootstrap3. There is no problem in chrome, firefox, safari, opera, 360 browser (speed mode), Sogou browser and other browsers. However, I found that the styles could not be displayed under IE8 and IE11, and then searched various Baidu, and finally solved the problem with the help of a netizen’s post. The solution is summarized as follows:

First you need to make sure there is a DOCTYPE declaration at the beginning of your HTML page. DOCTYPE tells the browser what HTML or XHTML specification to use to parse HTML documents, specifically affecting:

Constraint rules for marking attributes and properties
It has an impact on the browser’s rendering mode. Different rendering modes will affect the browser’s parsing of CSS code and even JavaScript scripts
DOCTYPE is very critical. The current best practice is to type in the first line of the HTML document:

<!DOCTYPE html>

The master’s post summarized several reasons for searching for bootstrap. First of all, Bootstrap3 was developed with the principle of mobile devices first, so the reasons may be as follows:

1. The remote address is not called correctly

That is, as long as it is IE9 or below, two special js are called

<!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries -->
<!--[if lt IE 9]>
 <script src="http://apps.bdimg.com/libs/html5shiv/3.7/html5shiv.min.js"></script>
 <script src="http://apps.bdimg.com/libs/respond.js/1.4.2/respond.min.js"></script>
<![endif]-->

But I tested and found that just using the above js file is not feasible,

2. The calling method is incorrect

Do not use file:// or @import forms to reference respond.min.js or respond.js or css files

3. Mark the content of the browser (use meta tags to adjust the rendering method of the browser)

bootstrap does not support IE compatibility mode. In order to allow IE browser to run the latest rendering mode, the following tags will be added to the page

IE=edge means that the latest kernel of IE is forced to be used. chrome=1 means that if the browser plug-in Google Chrome Frame for IE6/7/8 and other versions is installed (it can make the user's browser still have the menu and interface of IE, but the user When browsing the web, the Chrome browser kernel is actually used), then the Chrome kernel is used for rendering. For a detailed explanation of this meta tag, please refer to the excellent answers on StackOverflow. For an expert explanation of the tag in English, please refer to
http://stackoverflow.com/questions/6771258/whats-the-difference-if-meta-http-equiv-x-ua-compatible-content-ie-edge-e
I added a sentence

Then that’s it
The kernel controls the Meta tag. Because the current domestic mainstream browsers are dual-core, the meta tag is added to tell the browser which kernel to use to render the page

4.IE8 does not support several properties of container

IE8 does not fully support the use of box-sizing: border-box with min-width, max-width, min-height or max-height. Therefore, the container class in bootstrap v3.0.1 is no longer Use max-width.

5. Problems caused by the order in which JS and CSS are introduced

Must quote css first and then quote js

<link rel="stylesheet" type="text/css" href="bootstrap.min.css" media="screen"/>
<script type="text/javascript" src="js/respond.min.js"></script>

6. There are blank lines before and after DOCTYPE

It doesn’t work if there are spaces here, you have to remove them

7. You can also manually modify bootstrap.css
If you are using bootstrap2.1.1, modifying navbar-inner{ filter:none} can solve the problem. If you are using version 3.0, this code is no longer available. For details, please see the link
http://stackoverflow.com/questions/12460190/bootstrap-navbar-does-not-show-in-ie8

8. Use quirks mode (compatibility mode)

When defining a web page, the mode that is backward compatible with old browsers is quirks mode, and the corresponding "standard mode" is standard mode. Specifically, write as before
ttp://www.w3.org/TR/html4/strict.dtd">http://www.w3.org/TR/html4/strict.dtd">
I’ve tested this and it doesn’t work

Finally, I passed the test under IE11, but when I tested under IE8, I found a problem that placeholder is not supported

The following is how to solve the problem of IE supporting placeholder
The jquery cited in this article is 1.11.1 and passed the test. First quote jquery

<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>

You can also use other jquery versions
Then introduce
The download address of the jquery.placeholder.js filehttps://github.com/mathiasbynens/jquery-placeholder
Then add the code to the file

<script type="text/javascript">
  $(function () {
    // Invoke the plugin
    $('input, textarea').placeholder();
  });
</script>

The above IE6, 7, 8, 9, 10, 11, chrome, firefox, safari, opera, 360 browser (speed mode), Sogou browser test passed, only IE5.5 does not seem feasible, in short the problem is solved At this point, the evil IE6 - just call it soy sauce

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
