on top instead of shding ASCII Number as lavbel add flip icon and when fliped and when flipper keep same icon on same position

also the description whould be in diffrent color and padding from bottom should be less and make text bigger when flipped and make flipper card color diffrent or add some border to distinguish

Back not working

images should change as per letter

typing effect should adjust the cursor accoprding to letter length

this means there should be unique image as per letter( just like the board page could have) ? like aryabatta should have an arya batta image? if there's none there should be a placeholder or nothing?

since the pages is dynamically generated for all the pages same, how to turn off typing effect for this page?
