Mosh said that pseudo elements doesnt inherit the box-sizing, my question is, in what way not inheriting would affect the shape or size of our box? For example, when I do this my box is still the same the size, so is there any case where a pseudo element can change the shape of our box?

</div>

div::before {  
content: “hii”;  
display: block;  
}

Then you can set a width and height property.
