Cascading Style Sheets (CSS) play a significant role in web design, allowing developers to control various visual aspects of web pages. One essential feature of CSS is the ability to define borders around elements. This article aims to guide beginners through the concept of CSS Borders and their implementation.

I. Introduction to CSS Borders

A. Definition of CSS Borders: CSS borders are the lines that are drawn around elements, providing structure and definition. They can enhance the appearance of web content and make it easy to read.

CSS borders are specified through three main properties:

For example:
