Web Standards

A stylesheet, internal or external, specifies the style once for a range of HTML elements selected by class, type or relationship to others. This is much more efficient than repeating style information inline for each occurrence of the element.

Some of them have already reached Level what is css 4 or are already approaching Level 5.

A Deeper Understanding of CSS

The selector points to the HTML elements you want to style. The declaration block contains one or more declarations separated by semicolons.

Each level of CSS builds upon the last, typically adding new features and typically denoted[citation needed] as CSS 1, CSS 2, CSS 3, and CSS 4. Profiles are typically a subset of one or more levels of CSS built for a particular device or user interface.

Similarly, JavaScript or JS is used to add functionality to websites. When combined with HTML and CSS, JavaScript makes your website magical. Some examples of using JS in a website can be to navigate between the pages in your website or validate any inputs, etc.
