browser CSS extensions In addition to supporting the specified CSS properties set by the W3C, a browser developer will occasionally introduce browser-specific properties. This is often done for one of two reasons: n A spec is still under development by the W3C but the browser developer wants to start using the style now. The browser developer wants to try a new idea but doesn't want to wait for the W3C to accept it and begin work on it, which can take years. Sometimes the exact syntax of the official CSS specification will be slightly different from the "sand-box" version created for a specific browser. To avoid confusion and ensure forward compatibility of CSS code, each rendering engine has adapted its own prefix to use with CSS properties that are extensions unique to that browser.  These CSS extensions sometimes overlap and conflict when different browsers promote their own solutions. The good news is that due to the nature of CSS, you can include versions of each of the properties for individual browsers, so that the browser will use whichever version suits it.

Drupal8 W3CSS Theme - Padding Classes

Most HTML tags have browser inherited styles associated with them. These default styles are actually defined by the Web browser developer. Because the browser developer has added them, you need to remember that they are there and will affect your design.
