Despite following the instructions and keeping the width and height values as provided, the validator still throws an error saying: “You must not change the .bb1 width or height properties.”

height: 80%;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
}

Hi @davidwilliamguerra

You changed the height property value.
Try changing it back to 70%
