Now you know what the mainstream browser and its core it

The most important part of the browser is the browser kernel, browser kernel is the core browser, also known as "rendering engine", used to explain the syntax and rendered to the web page; browser kernel determines how the browser displays web pages the format and content of the page, the browser kernel also different for different grammar explanations pages so web developers need to test the effect of rendering pages in different kernel browser.

• Syntax different interpretations of the page
• Rendering is not the same
• Is not the same performance, support for script execution speed is not the same, and support for local (hidden elements, etc.) the situation is more complex repaint and reflow is not the same

Now domestic common browsers: IE, Firefox, QQ browser, Safari, Opera, Google Chrome, the browser Baidu, Sogou browser, cheetah browser, 360 browser, UC browser, surf browser, Window of the World browsers.

But at present the most mainstream browsers there are five models, namely, IE, Firefox, Google Chrome, Safari , Opera.

As a front-end development, familiar with the four cores is very necessary. Four different analytical core of the more diversified web page rendering, below summarize the core of each common browser you are using.

1. IE browser kernel: Trident kernel, also commonly known as the IE core;
2. Chrome browser kernel: the kernel referred to as Chromium or Chrome kernel, a former Webkit core, is now Blink kernel;
3. Firefox browser kernel: Gecko core, commonly known as Firefox kernel;
4. Safari browser kernel: Webkit kernel;
5. Opera browser kernel: originally own Presto kernel, and later Webkit, it is now Blink kernel;
6. Browser 360, cheetahs browser kernel: IE + Chrome dual-core;
7. Sogou, travel, QQ browser kernel: Trident (compatibility mode) + Webkit (high-speed mode);
8. Baidu browser, Window Kernel: IE kernel;
9. 2345 browser kernel: the kernel used to be IE, IE + Chrome is now dual-core;
