CSS has a set of conventions that are made up of a selector and a declaration block. The selector highlights the HTML element to be styled. On the other hand, the declaration block consists of one or multiple declarations that are separated by semicolons. The property name and the value in each declaration are also separated by a colon. CSS declarations are enclosed in curly braces.
CSS supports both 3 dimensional and 2-dimensional transformations. The transform feature in CSS allows developers to use methods like the rotateX(), rotateY(), and rotateZ(). Transforms in CSS depend on a set of properties. These properties can be used to apply linear transformations to certain elements of HTML. Some of the transformations that CSS can do include scaling, rotation, skewing, translation, etc.
The <style> element in CSS can be used to append CSS instructions into an HTML document. The <style> tag should be included within the head tags i.e. <head> … </head>. The CSS rules added using this syntax will be applied to each and every element in the document.
If you want to add a stylesheet file to your HTML document, you can use the link element. You probably already know that all external style sheets are separate text files with .css as an extension. Before you add an external text file to an HTML document using the <link> element, you must first define the instructions that are to be applied in that text file.
