Greetings @rafk, I hope you are doing well.

Your code looks good and the output is also as per homework. Just one thing I noticed is center alignment of title in exercise 1 which I think you missed by mistake. The output video shows how border corners trigger when you move mouse to top right and bottom left. Here it was asked the hover affect will change the corners from the opposite corners. You can fix it by using same code you used before keyframes and then apply keyframes with animation on border corners.

However the exercise 2 is perfectly explained in the output video. Your code is well documented as well. The gallery images are hovering and turning to straight point on mouse hover. I love this animation. Stay Blessed :)
