What does the property ‘font-weight: 800;’ in a CSS rule signify?

The property ‘font-weight: 800;’ in a CSS rule signifies a bold font. In CSS, the font-weight property is used to define the thickness or boldness of text. The values can range from 100 to 900, where 400 typically represents a normal or regular weight, and 700 is usually bold. When you use a value of 800, it indicates a font weight that is even bolder than the standard bold (700), resulting in a significantly thick appearance of the text. This strong styling can be particularly useful for headings or important text that needs to stand out in a design.
