🙋 Introduction

The border-left-width property in CSS is used to define the width of the left border of an element.

This property allows you to control how thick or thin the left border should be, and it can be set using various units of measurement. It plays a crucial role in creating visually balanced layouts by adjusting the borders around elements.

💡 Syntax

Here, value can be a length unit (like pixels, ems, rems), a percentage, or one of the predefined keywords.
