What is CSS? CSS stands for Cascading Style Sheets. CSS describes how HTML elements are to be displayed on screen, paper, or in other media. CSS saves a lot of work. It can control the layout of multiple web pages all at once.
The <style> tag is used to define style information (CSS) for a document. Inside the <style> element you specify how HTML elements should render in a browser.
An inline CSS is used to apply a unique style to a single HTML element. An inline CSS uses the style attribute of an HTML element.
To avoid caching of CSS.
If the website updates their CSS they update the ver to a higher number, therefore browser is forced to get a new file and not use cached previous version.
Otherwise a browser may get a new HTML code and old CSS and some elements of the website may look broken.
