An article analyzing the problem of IE being incompatible with CSS

In the process of web development, we all know that CSS is a style sheet language used to describe how HTML documents are presented. However, the extent to which different browsers support CSS varies widely. Among them, the incompatibility problem of IE (Internet Explorer) is particularly prominent, which brings a lot of trouble during development.

History of IE

First of all, we need to understand the history of IE. In the late 1990s and early 2000s, IE was once the most popular browser, occupying an absolute advantage in market share. Despite this, IE did not fully comply with W3C standard requirements at the time, causing compatibility issues during development. Later, with the rise of emerging browsers such as Firefox and Chrome, IE's market share gradually declined. However, because many enterprises and government agencies do not update their browsers in time during use, the usage rate of IE is still very high.

Incompatibility issues of IE

In IE6 and below, the support for CSS is relatively poor, especially in dealing with transparency, floating and positioning. There are many problems. Moreover, under the same CSS code, the display effects of different versions of IE will be very different, making it difficult to control accurately.

Solution to compatibility issues

We can use the following technical means to solve the incompatibility problem of IE:

1. Conventional method: formulate targeted CSS code , including IE-specific style code for compatibility processing.

2. Conditional comments: Use IE's unique conditional comments to perform special processing for IE. For example:

3.Polyfill: This is a simulation solution for JavaScript to implement API. Emulate unsupported CSS properties through JavaScript for compatibility purposes.

4. Use CSS compatibility prefix: Since different browsers have their own attribute prefixes, we can add the prefixes of different browsers in front of different attribute values, such as -moz-, -webkit- wait.

5. Use the CSS Reset library: Use CSS Reset to clear the browser's default style, making all browsers more consistent in performance.

Summary

The incompatibility of IE has always been an inevitable problem in web development, but we can use various technical means to solve this problem. In practice, we also need to continue to learn and summarize to improve our development level and ability to solve compatibility issues. Only in this way can we create better web page works while meeting the user experience and needs.
