It is a powerful tool for web designers to change the design and control over web pages and how they should be displayed. However, even when later “version 5” web browsers began to offer a fairly full implementation of CSS, they were still incorrect in certain areas. They were fraught with inconsistencies, bugs, and other quirks. X for Windows, as https://globalcloudteam.com/ opposed to the very different IE for Macintosh, had a flawed implementation of the CSS box model, as compared with the CSS standards.

How Does CSS Work?
Since prefixes are limited to a small subset of browsers, removing the prefix allows other browsers to see the functionality. An exception is certain obsolete -webkit- prefixed properties, which are so common and persistent on the web that other families of browsers have decided to support them for compatibility. This further decouples the styling from the HTML document and makes it possible to restyle multiple documents by simply editing a shared external CSS file.

Authors may change the style sheet without requiring modifications to the document. After the file is saved, it must be linked in the head of the HTML code using the tag. The following box shows an example of this element in use. Then, we will learn about the various types of CSS, its syntax, and its versions. You could picture it as if you were starting at the first line of the stylesheet and as you go down you grab styles. The browser support status is shown on every MDN CSS property page in a table named “Browser compatibility”.
