🙋 Introduction

The font-weight property in CSS is used to set the weight (or boldness) of the font.

This property allows web developers to adjust the thickness of the text, enhancing readability and emphasizing important content.

The font-weight property is versatile and can be applied to headings, paragraphs, and other text elements to achieve various design effects.

💡 Syntax

The syntax for the font-weight property is straightforward. It can be applied to any text-containing element.

Here, value can be one of several predefined keywords or numeric values that correspond to different font weights.
