Incompatibility between HTML and IE browsers

HTML is a Web page markup language, which is widely used in Web development. However, the performance of HTML pages in different browsers is very different. Especially in IE browser, HTML pages usually have various compatibility issues, causing the web pages to be unable to be displayed and used normally. The following will introduce the problem of incompatibility between HTML and IE browsers and their solutions.

1. Problems with DOCTYPE declaration

In HTML pages, the DOCTYPE declaration is used to specify the version and type of the Web page. In IE browser, if the DOCTYPE statement is illegal or missing, it will cause problems in the browser's rendering mode, thus causing various compatibility issues. Therefore, developers should add the correct DOCTYPE declaration at the beginning of the HTML document so that the browser can correctly identify the version and type of the page.

2. CSS style issues

In HTML pages, CSS styles are used to control page layout and style. However, in IE browser, the parsing and rendering mechanism of CSS style sheets is different from that of other browsers, which will cause CSS styles to not be rendered correctly in IE, causing the web page to not display properly. To avoid this situation, developers need to use techniques such as CSS Hack and conditional comments to solve IE browser compatibility issues.

3. Layout issues

In HTML pages, page layout is the basis of the entire page. However, in IE browser, layout confusion often occurs, such as incomplete display, misalignment, overlap, etc. This is mainly caused by the different parsing and rendering mechanisms of IE browsers for HTML page layout. In order to solve these problems, developers need to use standard layout frameworks and new features of HTML5 to ensure page compatibility and stability.

4. Problems with JavaScript

In HTML pages, JavaScript is the core technology used to achieve dynamic effects and interactions on the page. However, in the IE browser, because its parsing and support for JavaScript is not as good as other browsers, the JavaScript code will not be executed properly in IE, thus affecting the functionality and user experience of the entire page. In response to this situation, developers need to use technologies such as JavaScript Hack and compatibility libraries to solve the compatibility issues of IE browsers.

5. Problems with ActiveX controls

In IE browser, ActiveX control is a plug-in based on COM technology, used to implement various functions, such as media playback, Data collection, graphics processing, etc. However, in the current Web environment, there are more and more security risks and compatibility issues. In order to ensure the security and compatibility of Web pages, developers should try to avoid using ActiveX controls and instead use technologies such as JavaScript and HTML5 to implement corresponding functions.

Conclusion

To sum up, the problem of incompatibility between HTML and IE browser is a very common and serious problem. In order to solve this problem, developers need to carefully investigate and adjust all aspects of the HTML page, such as DOCTYPE declarations, CSS styles, layout, JavaScript and ActiveX controls, etc. Only by maintaining compatibility with IE browsers can we ensure the correct display and use of Web pages in different environments and platforms.
