Introduction to cross-browser compatibility

Cross-browser compatibility is usually understood as the ability of a website to look correct in all browsers. To do this, you need to know various techniques and features of browsers. We will study them now.

Currently, the following browsers are widespread: Google Chrome, Mozilla Firefox, Edge, Opera, Safari. Edge is the former Internet Explorer (abbreviated IE), which has changed its name.

In addition to browsers, there is such a thing as a engine browser. An engine is the basis of a browser that transforms our code into a picture visible on the screen. There are far fewer engines than browsers and, as a result, many browsers have the same engines and therefore the same features and bugs (problems).

Currently, the following engines exist: Webkit (Safari browser), Blink (Google Chrome, Opera14 browsers+, Edge79+, Safari), Gecko (Mozilla Firefox browser). The Blink engine is a fork of Webkit. There were other engines, but their development was discontinued: Trident (Internet Explorer), EdgeHTML (Edge), Presto (Opera).
